Many of you have followed my “how not to measure temperature” series showing many examples of the folly of thermometer placement in the USHCN network. But what about the rest of the world?
One of the most important things we look for is finding weather stations that are as far away as possible from human influence, so that they can resolve the “climate signal” unhindered and without need for retroactive data adjustments.
Weather stations on a remote mountaintop would seem to be a good candidate. Fred Harwood writes to me with one such example of a remote mountain station: Pointe Helbronner, Mont Blanc in the Alps, near the France/Italy border at 3462 meters high, about 11,358 feet.
Fred trekked to the top, to get this photo for us:
The temperature sensor is properly mounted inside the round louvered white radiation screen on the left side of the mast. The remote weather station also has a live webcam, as you can see in the photo (inverted glass dome) You can see a live webcam of this view here:
The latest image is a few days ago, so there may be a transmission problem.
The remoteness of such a station surely is impressive. Getting an accurate temperature measurement devoid of human influence would almost certainly be guaranteed, and we would not have to worry about nearby objects, people or buildings at such a remote location.
Well, maybe not….
And you can see more of the station and how it is situated (on the roof of a building) here in this YouTube video:
I suppose I’m not surprised. I’ll point out that this likely is not an official climate station. I don’t see it listed in GISS or NCDC. But the point remains, why go to all the trouble of a research quality temperature shield if you put the temperature sensor on a rooftop within reach of tourists? I’m sure that wood has an albedo of consequence and dozens of tourists also create a warm air pocket.

That is great. I really wasn’t expecting that.
Exactly, what is the point? No kind of consequential research can be done from there.
Looks like one person was so overcome with grief at the placement, they just collapsed! They’ve been irrigated!

Anthony, off thread, but I don’t have an E-mail address for you.
Have you seen these two papers?
http://users.bigpond.com/anne.foss/ecuador.pdf
and this one from Professor Alexander
http://nzclimatescience.net/images/PDFs/alexander2707.pdf
If you are aware of them, sorry for bothering you.
The second one seems to be especially interesting on several fronts.
Hope your house and family are OK and look forward to assisting you in your project.
How about just 12 thermometers? 1 for each continent and ocean. At what point do we say, ok we have enough measuring stations?
If I had a “fever” all you would need is one thermometer to take my temperature. Is the planet not 1 body? Are the oceans not connected?
I hate seeing soooo much money wasted on this HYPE.
There is a war coming in the middle east, Israel and Iran. Compile that with the developing nations demand for fuel and you will see prices sky rocket. You think they’re high now?
I suspect that some alarmists are happy with the price of fuel? If so, that is just sick! We need to start drilling from our own resources AND continue expanding alternative energy (not corn based ethanol).

Bet it has an UHI adjustment in GISS…
REPLY: It does not appear in the GISS database that I could find. – Anthony
You really need to watch the video and see that it is a large structure with chimneys protruding from the roof. So much for accurate air temperature readings on calm nights. You might also notice the glaciers on the nearby mountains. On the other hand, I need to get there somehow, I wanna pull out the snowboard and hang ten on that run! =:O~
Latest news; fewer then 100 fires burning n the State.
AP Lindlaw said onshore flow and rainstorms weren’t helping firefighters last Sunday. It was widely parroted by the reality challenged media.
Anthony, should have let me cuss that guy. Yahoo/AP/MSM axis of evil did an airbrush of their previous horsecarp article.
Truth is always a defence in libel cases.
The french will be really upset that you manage to put Mt. Blanc in Italy. Its in France and is the second highest point in europe (about 4.5 km).
Incredible amounts of snow at easter – I was there.
maybe the mountain moved.
If you had a choice to be French, or to be Italian, which would you choose?
French or Italian? They both have great food. Been there, done that.
How would you measure things at a remote mountain site? In winter, snow would cover everything. In summer, someone would swipe everything.
Satellite? How do they do initial calibration? Is/was it automatic, or do they base it on land measurements. Like GISS…
Another example of “We don’t know whats really happening.”
(without Anthony, we might have to believe what Al Gore is telling us.)
Lets see if I get this.
You’re saying that on the top of Europe’s highest mountain (15, 000 ft odd) there are going to be enough days when the wind so light that air can be heated up by tourists (yes, tourists) and the roof and rise up to materially effect the temperature record there?
Are you being serious?
REPLY: There are published World Meteorological Organization (WMO) standards for thermometer placement. This violates them, simple as that. Those standards exist for a reason, and the reason is so that the data is free of any potential bias and therefore free of arguments like this one over whether or not the data is or is not biased and to what degree. Adherence to standards negates the issue. Unfortunately we keep seeing this poor placement again and again. – Anthony
Here are two SST anomaly data sets I pulled from ERSST.v2 on NOAA’s NOMADS system. I guess no one told Smith and Reynolds they needed to make adjustments for urbanization, etc.

Funny how current temperatures aren’t close to the peaks of earlier rises.
It appears both France and Italy claim Mt. Blanc (French) or Monte Bianco (Italian)

Mr Mark W asked: “If you had a choice to be French, or to be Italian, which would you choose?”
I’ve been saying for years, and will say until my liver takes its final gin, you can’t trust any country that makes runny cheese.
Donning the dunces cap for a moment, I have a question.
I can understand the general proposition that an accurate measurement of temperature trends requires three things:
(i) the measuring device itself must be reasonably accurate (hence one would prefer to use a properly calibrated thermometer rather than a home made device with graduations marked by fingernail scratches),
(ii) the device must be placed where it provides only relevant information not irrelevant information (hence, don’t put it next to the oven at the local bakery or in the ice cream freezer at the supermarket) and
(iii) the readings taken must themselves be directly comparable (measuring the temperature at 8am in January, 9am in February etc up to 7pm in December would be neither use nor ornament).
These basic points would mean that we could compare like with like. The more refined the calibration of the measuring device and the more readings that are used, the more accurate will be the calculation of averages.
I can also understand that it might be practically impossible to avoid all irrelevant variables because measuring devices have to be put somewhere (unless they are remote devices, as I believe satellite measuring devices to be).
It seems to me that all pre-satellite era temperature records are likely to have been affected to a greater or lesser degree by problems of (i) calibration, (ii) irrelevant influences and (iii) an insufficiency of data points. The first and third problems are perhaps more likely to affect older records and the second more likely to arise in records from industrialised times and industrialised places.
When analysing data to provide a trend, I presume that the statistical concept of “noise” can help to even-out the worst excesses of (i) and (ii).
My dunce’s question is whether it can also even-out (iii).
My initial reaction is that it probably can, provided there are sufficient readings from places unaffected by significant irrelevant influences to show two distinct trends – one in the affected places and another in the unaffected – from which the effect of the irrelevancies can itself be displayed.
Am I spouting sense or is it time for a little hemlock to be added to my evening gin?
ROFL The AGWers want so badly to have their claim that humans control the climate to be true that they’ll do anything to make it happen!
To measure temperature theree, would you measure above the snow? Or above the rock? What if the snow melts or increases over time?
Or would it make better sense to measure above a more stable platform such as wood? Unless the wood platform rots/loses it paint over time. Fake grass matting perhaps?
How would you site a station in such an area?
Cheese Shop Owner: “It’s a bit runny, sir.”
Cheese Shop Customer: “I don’t care how excrementally runny it is, hand it over with all speed.”
Geez, you don’t think kids would be having fun using this equipment as target practice for snowball throwing. I’m still waiting for summer to arrive, it went down to 6 C a couple of nights ago and struggles to get to 20 C here. Calgary has the sunniest weather in Canada and can’t remember a more cloudy year in my 38 years here.

Peter Hearnden,
I would tend to agree with you about the tourists. That ignores the issue with the smoke stacks and general building waste heat that will not be consistent from day to day or season to season!!!
Of course, a group smoking cigars or pipes might actually cause a blip. ;>)
How about Al Gore as the tour guide. That would kick a few extra C on the reading!!
The swiss wetter data
i believe they have good wetterstations, all well maintaint
is in the centre off europe almost all mountains..

Re, FatBigot’s (Wonderful name, Sir) query about the errors in measurements. Basically there are two types of error, random and systematic.
Random errors are centred on the “true” value (which you can never know) and roughly follow the “bell curve” distribution. They are otherwise known as “noise”, and can be dealt with by making your instruments as carefully as possible and taking a large number of independent measurements and calculating the mean value.
The big problem with nearly all practical measurements is the systematic errors. These all tend to go the same way, and thus cannot be averaged out. As an example, if you wanted an accurate measurement of the temperature of a pot of boiling water using a hand-held thermometer (DON’T try this at home, it hurts!) you would have to remove the thermometer from the water to read it, and as soon as it leaves the pot it starts to cool down. Therefore, all your readings will be lower than true by varying amounts. Taking the mean here is obviously pointless.
Unfortunately, all the examples FatBigot gives are systematic. Type 1 could, due to a calibration error, have its scale shifted up by half a degree, Type 2 (which is the main point at issue here) be near something that was persistently warmer or cooler than the “true” temperature, and Type 3 will, as he implies, show a totally fictitious periodicity.
We have to be very, very careful about systematic errors, in particular because the buggers are adept at hiding among the random ones and not being allowed for, like UHI.
