From Mike Bastasch at The Daily caller and the “told you so, again, and again” department.
U.K. meteorologists won’t be declaring a June 28 temperature reading as the hottest recorded in Scotland since the early 20th century after discovering a car parked near the weather station may have contaminated the data.
The city of Motherwell, southeast of Glasgow, recorded a record-high temperature of 91.8 degrees on June 28, according to Met Office figures, breaking the previous record of 91.2 degrees set in Greycrook in August 2003.
The record temperature reading even found its way into the Washington Post. The Post’s Capital Weather Gang included Motherwell’s heat in a round-up of record-high temperatures around the world.
“No single record, in isolation, can be attributed to global warming,” the Post reported, trying to link summer weather to global warming. “But collectively, these heat records are consistent with the kind of extremes we expect to see an increase in a warming world.”
However, the Met Office posted a blog post on Thursday noting “subsequent information has cast some doubt on the Motherwell measurement for that day, meaning that we will not be able to accept it as an official new record for Scotland.”
So what happened? It turns out exhaust from a nearby vehicle may have heated up the weather station that reported the record-breaking heat.
“At first review the Motherwell record appeared plausible given the wider conditions on the day and was therefore reported as such. However for all new records we undertake further careful investigation to ensure that the measurement is robust. This investigation includes statistical analysis of the station data, evaluation against neighbouring sites, and in some cases an additional site visit to check for unexpected issues with the instrument enclosure or equipment to ensure the measurement meets our required standards.”
“Unfortunately in this particular instance we have evidence that a stationary vehicle with its engine running was parked too close to the observing enclosure and the Stevenson screen housing the thermometers during the afternoon of 28th June,” the Met Office explained.
“Although the measurement appears plausible given the weather conditions that day we cannot rule out the potential for contamination of the measurement by this non-weather-related factor,” officials wrote.
This is a common problem for weather stations. Many are located in urban areas, especially airports, where they’re susceptible to urban heat islands (UHI) — anomalous warmth present in cities.
In fact, a major study released in 2015 found the majority of weather stations National Oceanic and Atmospheric Administration (NOAA) relied on for temperature readings were poorly sited, meaning they were contaminated by artificial heat sources.
“The majority of weather stations used by NOAA to detect climate change temperature signal have been compromised by encroachment of artificial surfaces like concrete, asphalt, and heat sources like air conditioner exhausts,” said Anthony Watts, a seasoned meteorologist and lead author of the study.

I’ve spent a lot of time trying to locate the Stevenson Screen, to no avail. It’s somewhere in this complex if the lat/lon is accurate.
Anyone want to have a go?
Paul Homewood suuplied the Lat/Lon which he dug out of the Met Office page.
It’s 55.786, -4.022, which also corresponds with their site:
https://www.metoffice.gov.uk/public/weather/climate-network/#?tab=climateNetwork
UPDATE:
Nick stokes tries to minimize the importance of this station in comments.
Motherwell is not in any set of stations likely to be homogenised or used for homogenisation. Or used for any major temperature index.
But, the Met Office lists it as a “Manual” climate station:

The utter absurdity of using ground located thermometers that are not confined to a secure, grade AAA location as part of a proper ‘global’ system is beyond me especially with the massive increase in the amount of surface bitumen and concrete in likely proximity. GForget about increased CO2 in the atmosphere, just try heat island materials on the surface. It will be orders of magnitude greater.
“as part of a proper ‘global’ system is beyond me “
This site was not part of any ‘global’ system. There are many sites around the world, run by Met Offices or not, whose purpose is to tell the locals about their weather. They aren’t all AAA.
So what? You know full well that the MSM, and various and sundry NGOs would pounce on that “record” to help push their Climatist agendas. It’s straight out of the “Climate Communication” handbook.
Bruce, what is that wonderful quote about arguing with fools? Ought we to know better by now?
although in this case the term LIAR is much more appropriate. And Oh By The Way, a person can be a self-deceiver and still be a liar, in fact, that is the worst type.
Nick, basically ALL the land based surface thermometers were set up for that purpose and all they are doing when used for the ‘globsl temperature’ confection is indicating the UHI trend over time. Sweet FA to do with CO2 in a direct sense. That some are now only used locally is as it should be for most of them, except the AAA ones. Unfortunately AAA sites don’t produce HOTTEST EVAH !!! headlines.’
Washington Post sees it fit to make this go “global” for propogands purposes.
Tip – most locals don’t live at the parking lot in their cars.
Although that number may be increasing, as people are run out of their homes by the exorbitant expense of trying to pay for “renewable” energy.
Confuscious say: he who runs in front of car gets tired, he who runs behind car gets exhausted.
So, if a vehicle exhaust is close enough to cause a change in temperature measurement, this means that there is a parking lot associated with the measurement site which has caused additional warming over ambient conditions for some time. And knowing how temperatures are “smoothed” over different stations, any rural station within, what, 1000 KM, has been homogenized with this station next to a parking lot.
And the Warmist’s discount the satellite record as not be representative of terrestrial temperatures. Go figure.
Motherwell is not in any set of stations likely to be homogenised or used for homogenisation. Or used for any major temperature index.
The met office lists it here:
https://www.metoffice.gov.uk/public/weather/climate-network/#?tab=climateNetwork
It’s listed as a “Manual” climate station. Nice try Nick.
That doesn’t contradict anything I said. The station is not part of GHCN monthly or daily, and is not included in the major temperature indices. Nor is it likely to be involved in any homogenisation, as implied by the comment I was responding to.
I agree that the “record” should have been removed, it was clearly erroneous (once they investigated). Just like the Honolulu record temperatures were removed once NOAA found the instrument was faulty and replaced it. Oh… wait… https://wattsupwiththat.com/2009/06/17/noaa-fubar-high-tempclimate-records-from-faulty-sensor-to-remain-in-place-at-honolulu/
Nick,
I must agree with you that the site is likely not used for official reporting or statistics WRT climate reporting, it is merely a poorly sited station used by the WAPO for “Proof” of Global Warming and the associated Media Disinformation
campaign
But it was in the set of reporting highest temperatures ever recorded. Pardon my doubting your assertion that it was good enough for that but not anything else.
Actually, the report says it was influenced by a car. So it may be just opposite what looks like the jetty as there is a road there and a car may have been standing there while offloading.
Also it is interesting, Nick, that it was important enough to claim a record but not important if it wasn’t a record?
55.786345, -4.023465
That looks as good as any other guess. Yes, it looks like there’s a turnout where a car could wait for passengers or for a technician to take a measurement.
Looks more like a historical plaque. The planted trees in the arc around it suggest the same. If it *is* a measurement station, being that close to pavement and having a windbreak are a big no no.
Hah! There is indeed a plaque there to “The Piper Alpha Disaster” — a photo panorama someone did.
“that it was important enough to claim a record “
Anyone can measure temperatures for any reason, and claim a record, if they think right. It’s then up to the Met Office to investigate the claim before accepting it, as here.
And of course we all know how honest the Met O is…..just like you are Nick.
“Also it is interesting, Nick, that it was important enough to claim a record but not important if it wasn’t a record?”
and there is the rub, right there, for all to see! When I first visited this site, I was still on the fence because I hadn’t researched much of the nitty gritty. So, I read through the comments section, as I do now because it is both fun and enlightening. After a few years what I have come to notice is that Mr. Stokes is a Prime 1 Grade A obfuscator. I just call them liars, but, maybe that is too harsh for the mods.
Nick, you are the most cherry-pickeninist, instransigent, obfuscator I’ve seen and it is unfortunate because it appears you have enough intellect to know better
“And of course we all know how honest the Met O is”
Well, the only basis for this whole kerfuffle is that the MO, on their own initiative, investigated the reported reading, and discovered and reported the issue about the car exhaust. That doesn’t come from anyone else. Do you think they are lying about that?
Brilliant.
Too little to late Nick. The story is out there in the WaPo. Do you think they bothered to print a retraction?
this is my frustration with Nick, because he refuses to admit his errors or the real world working mechanisms of corruption and collusion (only because it fits his agenda). It is frustrating because I know he’s smart, and I see many smart people stuck in the cave, trying to kill the one free slave that got out and came back to try to free them.
the allegory is real
“Do you think they bothered to print a retraction?”
Yes. The WaPo story : now reads
“Previously, it was reported that Scotland set its hottest temperature on record of 91.8 degrees (33.2 Celsius) on June 28 in Motherwell, about 12 miles southeast of Glasgow. However, upon further evaluation, the U.K. Met Office determined the record was invalid due to an artificial heating source near the temperature sensor.”
Thanks for point that out Nick. Always worth taking these rhetorical questions literally and checking them out.
Heck, the “official” weather station for Boston is located right next to a runway at Logan airport! Talking 30 or 40 feet from the edge of the runway.
When I say “official”, I mean what the “city” TV stations report. It’s quite laughable.
Probably bad form to reply to my own post, but…
Checked a few things to make sure my post above was accurate as it’s been a few years since I checked this out. At first I could not find it on google map aerial view. It used to stick out like a sore thumb between 2 runways (4L and 4R as I recall)
There’s been a lot of taxi way work and other temporary structures in the area so it might be easy to miss in all this clutter.
So I went to WUNDERGOUND to get the Lat/Lon of “Logan International”. Sure enough when I checked my charts (used to race sailboats in this area) it was right where I remembered it.
But and this is interesting (at least to me) WUNDERGROUND typically shows the weather station you are monitoring on a map of sorts. Not true in this case. Now way could I see it. I got the data and history from that site no problem. But no map visual location. Rather odd?
Will also add, that as expected Logan International appeared to be 3 to 4 degrees (F) warmer that all the surrounding stations.
There aren’t any obviously valid locations for a temperature monitoring site there – the only good spot seems to be out in the middle of that big, empty field.
If a car could be parked next to it, the thermometer’s probably either by a road or next to that big, hot parking lot.
I keep looking out on the piers. That’s where I noticed them when visiting lock and dam sites on the Ohio River.
I think that “big empty field” is overflow parking.
Official Lat/Long are often given for the HOST of the site — the one for Santo Domingo was set in the middle of the mouth of the Ozama River — it took me almost a week to find the official site with the actual equipment actually in use. One site, in front of the National Weather Service was obvious — but not in use for fifty years. Out behind the building, in the middle of of a corn field, was the current site — with a mix of failure equipment and newer AWS. The AWS was out of service but the old Stevenson screens was there, thermoters and all, plus a concrete block for the shorter weather records to stand on to read the thermometer at eye level……
Kip, don’t post and drive…
Only teasing you, Kip. You obviously mean ‘recorders’
Great comment.
So what happens to the readings when the corn is harvested and the sun shines on the bare ground? All fall, through the winter and whenever the ground is left fallow.
And is the land irrigated?
I looked around the carpark in map and street view. I can’t find any plausible location for it.
We know that the coordinates aren’t always accurate. So with that in mind I looked further afield. I can’t find anything that looks like it might be a weather station.
Streetview car drove through part of the parking lot. Google Maps shows some trees have been cut down since this article’s photo. https://goo.gl/maps/YWpM65aaB5r
Are we sure it is a Stevenson Screen and not an Automatic Weather Station?
Yes, met office lists it as a manual station, and they allude to a Stevenson Screen in their report.
When you are in the business of homogenization, it doesn’t matter what the measuring device is, nor where it is located.
There is no evidence that this station is involved in homogenization. It is not likely to come to the attention of the NOAA. They do not list it in GHCN, either monthly or daily.
Nick apparently believes that repetition of the same irrelevant argument will do the trick. The issue is not whether this bad sample will come to the attention of the networks, but that it was reported and has influenced those who read the reports. These people don’t even know who the official temp network orgs are.
Nick’s argument is not irrelevant in the slightest. Yours is – projecting influence on unnamed individuals who will read “the reports” – whatever that means – and then take action based on reading “the reports”.
BBC Radio Scotland discussed it live this morning and whoever the expert was, confirmed the use of a Stevenson Screen. The interviewer had never heard of a Stevenson Screen.
All this froth and gnashing over a possible rubbish bin. It would be truly hilarious if not for the fact there are so many high records being set and so few lows. But we don’t mention that here, it doen’t fit the narrative.

Not in Western Australia. We had a “record” cool summer for the second year, with cool humid air from the southern oceans instead of hot dry air from the desert interior. The BOM actually reported this, rather grudgingly.
Zazove
The earth IS warming. Most people accept that. The earth has been warming since the late 1800’s. It would therefore be strange not se see the odd record high. It’s just that they don’t happen very often. No news here.
Zazove :
I think it’s MORE like the last 20,000 years or so……..but I can’t
personally vouch for MOST of that time !
Zazzy’s nonsensical distractions, repeated ad nauseum.
Australia’s BOM, such a trustworthy group…
Haven’t ye learned that facts are of no consequence to the “woke”, such as zazove and mosh?
Don’t you know corruption only occurs with Koch funded denialist Republicans? Hillary is a saint and up is down, 2+2=5, oh and there are currently 17+ genders micro aggressing each other in competition to see who is most victimized and therefore going to go to atheist heaven?
It’s a bummer that the warmunists can’t claim this one as the record stays at August 2003. That’s 15 years ago which is half of a climatic research time frame of 30 years.
I recently did an energy audit of a large high rise building. I was examining the building HVAC (heating, air-conditioning, ventilation) system and noticed it was cycling heavily, with the airside economizer energizing/de-energizing. This would then cause the chillers to cycle.
Tracked down the reference outside air sensor, which was on the roof. It was 10’ away from the cooling tower exhaust, at the same elevation. DOWNWIND!
The sensor is being relocated.
One example of many.
Hey! That’s my job! Keep up the good work!
A climate alarmist always want to shove a thermometer up his/her butt and tell us how hot the house is
That must put pressure on their brains!
Oh good. There weren’t x warm records, there were x-1.
I feel much better.
And your evidence that 100% of the other stations do not have similar problems is????
Oh good. There weren’t x warm records, there were x-1.
And “told you so…”
From the Really? department.
[ Yes, really like this one that was closed for making bad data. But people like yourself don’t care about such things. – Anthony]
“People like you” claim some high moral ground yet ignore the substantive elephant in the room: the disproportionate number of high records.
Supposes facts not in evidence. Last time I checked, if I focus on rural stations only (to try to attempt to minimize UHI, though even rural stations’ population’s increase) the average age of record high temperatures is older than the average age of record cold temperatures. If record temps is all you’re going to use, kinda takes the wind out of your sails doesn’t it.
Can you show us your evidence Red.
Why? You didn’t show us yours.
You got any direct evidence for your libellous specious falsehood there zazzy?
Nope, just more zazzy hand and butt waving, that zazzy uses to try to distract from real science.
Then a demand that others prove him wrong.
would you argue with a 19 year old? I’m fairly certain that is the age of zazove. It makes us look silly and we’re better than that
Who says they are disproportionate?
Anecdotally we can see the world has been warming as it comes out of the Little Ice Age. But the instrumental surface temperature record has been so badly recorded or post hoc altered, we just don’t know for sure.
Yeah, “we just don’t know for sure.” However, last year after I died and went to heaven, I asked God about the REAL average global temperature, and whether or not it had actually been increasing over the past few decades. He just smiled at me and said, “Just wait. You ain’t seen nothin’ yet!”
Sounds like he had other plans for you.
Good one, Nick!
Too bad temperature does not actually correlate to energy(heat), but God and every highschooler who has had to stick a thermometer in a glass of ice over a bunsen burner knows that. now if we could just get NOAA and NASA to realize it.
I’m sorta suprised that the Met Office actually withdrew the purported record high, as it fit the narrative.
Had they not, they knew that James Delingpole would be on their case, making hay while the sun shone.
It hasn’t deterred them in the past.
But the times, they are a changin…
I smell a rat, I feel it in the air, we must nip it in the bud…
Good collection of mixed metaphors! (And it makes a clear point as well)
Disgraceful that they use this station. Science is dead.
Never attribute a conspiracy to what might be just incompetence but I find it suspicious that a car parked with its exhaust facing a weather station with its engine running a little suspicious. Surely it was a no standing zone.
I thought it might be at: 55.786343, -4.023458
After 20 minutes of looking for maps, photos, and dancing unicorns, I could find nothing of interest.
I went on to a different project.
That is the memorial stone for the Piper Alpha disaster… https://www.google.co.uk/maps/@55.7863691,-4.0233997,3a,90y,3.9h,76.47t/data=!3m8!1e1!3m6!1sAF1QipNse_5icH-sJBcWCAGTOI7RLlUPmPjGIVDZe0nF!2e10!3e11!6shttps:%2F%2Flh5.googleusercontent.com%2Fp%2FAF1QipNse_5icH-sJBcWCAGTOI7RLlUPmPjGIVDZe0nF%3Dw203-h100-k-no-pi-4.2478952-ya105.45654-ro6.7754273-fo100!7i7200!8i3600
I found it. The marina is on the South shore of the lake so the posted pictures are turned around. In the back parking area, west end, you will see a path running west. Follow that path until it intersects a North – South path and stop. The screen is right at the intersection on the North West side. You can clearly see the shadow from the wind vane.
I tried your instructions, and didn’t see anything recognizable…if your are using Google Earth, you can put a marker in place and it will give you an accurate lat/lon. Can you do that and post it here?
I think I see it. To the right of the building there is a field. There’s a road/path that runs from the parking lot to the main road. Going left to right, there is another road/path that intersects the first path at nearly right angles. In the lower right quadrant formed by the intersecting roads, you can see a dark spot.
I’m talking about the second picture, the ones with the docks pointed downwards.
PS: From the layout of the paths, it looks like the field is used for overflow parking.
I think this is it: https://www.google.com/maps/@55.7856124,-4.0236262,3a,15y,298.77h,89.37t/data=!3m6!1e1!3m4!1sEVeJ1katiUYe0jPgvsejqw!2e0!7i13312!8i6656

What is this? 55.788812, -4.030008 Why that peninsula out into the water? What’s on it? I can’t find a street-view of it.
If the Stevenson Screen is close enough to the asphalt for a car to be parked close the the screen, then the parking lot alone is enough to disqualify this sensor.
Disqualify from what?
Establishing a record temperature for Scotland?
Oh, please, Nick. Haven’y you learned anything from the closures NOAA made to stations like this one?
The question remains, disqualify from what?
There is no likelihood that this station will be used by NOAA, or ever has been. You mentioned above that it is listed as a manual station; that is not high praise. The Met blog post listed says:
“At the Met Office we manage a network of weather observing sites across the UK. This network is comprised of approximately 259 automatic weather stations managed by Met Office and a further 160 manual climate stations maintained in collaboration with partner organisations and volunteer observers. “
Here is the WOW page for Motherwell Strathclyde Park. It has a one (out of five) start rating. Under Site details, it says
Reason for running the site: Education.
It seems like this station was a candidate to produce a record temp for Scotland had they not found the car parked there.
Thus disqualify it from being a station that can define record temps in Scotland.
It seems they did just that.
No they didn’t disqualify it Nick. They announced a record and then changed the announcement. Nobody has declared there will never be claims of records from this station again.
“They announced a record”
Are you sure? Seems to me that other people announced it, and the Met Office checked it, as is their process. The MO can’t stop people claiming records.
BBC Radio 4 forecast on July 3 at 17.57: staff forecaster, Nick Miller, announced it. Miller will have got his info from the MO.
I heard it live and it’s on iPlayer Radio in the U.K. or elsewhere possibly via VPN.
thus the sophists trick: make an adjacent claim knowing full well the implications.
blame it on other people even though they had to get the information from said source, but pretend relaying the information isn’t “announcing” it. Those are sophist tactics.
THAT WAS THE SOURCE, THEY ANNOUNCED IT TO NICK MILLER
Or they provided the information in a form that was accessible, which, yes, would mean the MO didn’t announce it over the radio, but they provided the fake data to someone whom they knew would.
It is for all intents and purposes the same thing.
I’m sure you believe 2 planes brought down three buildings, and the one that wasn’t hit; global collapse by fire. But wait, NIST never released their computer model data to explain how they made that magical building 7 fall, because “national security”. That’s the type of cognitive dissonance you live in bud. If it’s models you trust that more than reality smacking you across the face.
No, Miller will have been watching the max temps from Scotland whilst on duty that day, because the air-mass resident “could” have given rise to a new Scottish record max (as was signalled by the MetO the day before). He saw it reported as being higher than the existing record and said so on his b/c. I would have done the same back in the day. Then came the verification process. There is a difference between being reported as being the highest max record seen just after it’s recording and the verification of it, which obviously takes investigation after the fact. Which the MetO duly did.
Ah, I see.
Back in the days when we had meteorologists, it was “verify, THEN report.”
Apparently not the case today, when we have “weather journalists.” They fit right in with all of the other kinds of “journalists” – report what sounds good for their agenda. Occasionally, they do verify – but make sure that the correction is on page 34 along with the obituaries and lost dog ads.
“Apparently not the case today, when we have “weather journalists.”
Nick Miller is a trained meteorologist, as am I.
Oh come on Nick: “Scotland has recorded its hottest ever temperature, according to provisional figures from the Met Office.”
Then they didn’t immediately disqualify it because of the quality of the station, but instead of a single incident of car parked nearby.
https://www.bbc.com/news/uk-scotland-44683637
The Met office runs, according to that blog, a “network comprised of approximately 259 automatic weather stations managed by Met Office and a further 160 manual climate stations maintained in collaboration with partner organisations and volunteer observers”. They post temperatures for them every day. They would have posted the temperature for Motherwell in the usual way. Anyone could have noticed that this exceeded the previous record, attributing the actual number to the MO. It could even have been a MO employee. But the MO has a policy about declared records, and they followed it.
Met office seems very happy to keep this station as part of their “high-quality climate-observing network for the nation” [1], indicating that it could be used one day to set a record.

Nick Stokes says;
” Under Site details, it says

They should have added “to show where not to site a weather station”
One trick Nick.
you mean one dick wit, that’s our Nick.
the modern left have devolved into Neanderthal like world vision. There is nothing else to it. History repeats and the real fascists have exposed themselves. Sadly, many good, intelligent leftists aren’t standing up to these types of extremists.
Nice ad hom. Well done. (sarc)
From producing usable data.
I once checked the outside air temperature (OAT) gages on four helicopters in a hangar hoping to find the one with a slightly low engine power problem, reading lower than the other three. All four read four different numbers some different by 4 degrees C. No hangar heaters were running and the aircraft were about 50 ft apart. An error in the OAT will cause an error in the engine power available calculation and could result in an unnecessary engine change.
These temp sensors are designed for aircraft and nothing designed for aircraft is done on the cheap. I just can’t get excited over a few tenths of degrees.
Modern temperature sensors are digital and we associate them with electronics, computers and greater accuracy. Their location, quality of manufacture, calibration, power input, length of wiring and other issues make them no more inherently accurate than glass thermometers. Working in the HVAC industry I have seen many, many problems- some major, from trusting digital temperature readings that weren’t accurate.
John. I was going to add a thought I had at the time which was if I had asked two maintenance guys to record the Temps then I would have had eight different numbers because the temp gage was an analog dial type with five degrees between graduation marks. Most tech people today don’t know about parallax error.
They are all analogue actually. They may output digital data but all sensing elements pt100, thermocouple, thermometer and semiconductor are all analogue.
You are describing what has occasionally been a discussion here on WUWT, and a frequent reference during discussion.
i.e.
A) the failure of NASA/NOAA to track and quantify error bounds,
B) NASA/NOAA’s frequent abuse of alleged precision,
* 1) Contaminated temperature stations, without identifying temperature bias. Increasing temperature bias over time is ignored
* 2) Annual equipment replacement, without before/after or side by side instrument checks.. Responsible agencies assume factory accuracy specifications without verifying or certifying. N.B. Area, regional, state, national temperatures are sums of many individual instruments that get this basic treatment.
* 3) Anthony’s excellent research has identified temperature station installation bias and contamination.

Anthony includes a link to the Daily Caller article above.
Technically, the list of temperature process/equipment error ranges is quite long. Government’s wilful blindness and litany of failures to track and properly aggregate process/equipment error ranges is simply astonishing.
* 4) Government’s near constant manipulation of recorded temperatures, most are adjusted for vague reasons/rationales.
* 5) Government infilling temperature records; some are missing, some are places without temperature measurement stations, others are temperature records that the agencies dislike. Government freely uses temperatures from stations up to 1,200 Km away for infilled estimates.
Government ignores that adjustments are error ranges admissions. Error ranges that are not decreased through using estimated temperatures.
To reduce the problems handling/escaping from wasp nest inside the “beehives”, can you not try reversing the order?
Open the door, inspect the inside for other insects or damage. If a nest is inside, immediately put the plastic bag over the entire enclosure and tie-wrap it tight below the enclosure at the post. Then remove the wrapped enclosure (this might require a slight mod to the mounting bolts on the bottom of the beehive to the post to make unbolting the beehive from the post faster with a bag over the box.) and put it in the truck.
Or, just squirt bug killer into the bag and wait a few minutes for the interior trapped insects to die.
Does the UK not still use glass thermometers in at least some stations?
My mother, a Glasgow girl, was shipped off to live with her grandmother in Motherwell at the outbreak of WW2.

We have photos of my uncle aboard HMS Curacoa not long before he was killed.

Much respect to your Uncle and his sacrifice.
55Degrees 47’9.01 N
4 Degrees 1’27.46 W
Doesn’t work on Google Earth
Try 55°47’9.01″N 4°01’27.46″W
That’s a rubbish bin.
I was just clarifying for markl the location that Bob M gave.
Have a look at 55.788539, -4.029825 (55°47’18.7″N 4°01’47.4″W) instead. Possible wind vane shadow, white box?
That’s a Mann 1000 heater for weather stations!
How about 55.785860, -4.021550 ?
Probably not, looking at pictures of the marina there doesn’t seem to be a screen there.
looks like a lamp-stand https://www.google.co.uk/maps/place/55%C2%B047'18.7%22N+4%C2%B001'47.4%22W/@55.7880106,-4.030213,62a,35y,39.59t/data=!3m1!1e3!4m5!3m4!1s0x0:0x0!8m2!3d55.788539!4d-4.029825
Why did you abandon 55.788539, -4.029825?
I didn’t. I was just clarifying for markl the location that Bob M gave.
That’s not it………….
Anthro, auto-pogenic warming
Is this it?
55°47’48.21″N, 4° 2’4.45″W
I would go with that – though the siting is strange…
BBQ? https://www.google.com/maps/@55.7973859,-4.0346686,3a,15y,177.61h,83.95t/data=!3m6!1e1!3m4!1s3CfmA2J-sizQexszThIzwQ!2e0!7i13312!8i6656
Either way, the station is poorly sited if it’s at the slightest risk of being influenced by a parked car. Seems like it much be located adjacent to a significant area of concrete and/or tarmac.
On Google Maps there is a white rectangle near to the end of the white-roofed building with one half-rounded end. If that’s it, it’s a very unsuitable spot.
https://www.google.co.uk/maps/place/55%C2%B047'09.6%22N+4%C2%B001'19.2%22W/@55.7854902,-4.0225639,135m/data=!3m1!1e3!4m5!3m4!1s0x0:0x0!8m2!3d55.786!4d-4.022
That’s either a rubbish container or a container for winter sand/salt. You get a good ground view of it here https://www.google.co.uk/maps/@55.7852841,-4.0230339,3a,75y,37.01h,66t/data=!3m6!1e1!3m4!1sHL3fIpqvzHCYIp4z_pPtbA!2e0!7i13312!8i6656
Another possible site – though surely a poor one – might be the white smudge to the NE of the bandstand here: https://www.google.co.uk/maps/search/Strathclyde+Park+Aquasports+Center/@55.796236,-4.0346404,52a,35y,45.06t/data=!3m1!1e3
You can’t get a good ground level view – but the ones that you can get show a screen-sized object on 4 legs. Doesn’t look very white, though, and I can’t see why a car should be close to it. Best view I can get is: https://www.google.co.uk/maps/@55.7973859,-4.0346686,3a,15y,179.43h,85.58t/data=!3m6!1e1!3m4!1s3CfmA2J-sizQexszThIzwQ!2e0!7i13312!8i6656
Maybe a BBQ?
Wouldn’t a stevenson screen be protected with a fence?
is the fence to keep the hot air in or to keep the cold ait out?
55.784958, -4.022874
Nope – that looks like a bus parking spot – https://www.google.co.uk/maps/@55.7850242,-4.0227743,3a,60y,199.5h,83.29t/data=!3m6!1e1!3m4!1svt4K-hZG1Q5OQvif3OiyjQ!2e0!7i13312!8i6656
Note the shadow of a pole over your bus parking spot and 2 small white items.
This is a necessary set-up for the car being next to the temperature sensor.
Sorry, it is a light pole with a security camera.

there is what seems to be a white box in the corner of the field. But also a strange little structure in the middle of the asphalt at the entrance of that boat pen.
