Poorly sited weather station leads to a fake record high in Germany

From Pierre Gosselin:

Lingen Cheated: Germany’s New All-Time Record High Resulted From DWD Weather Service Lousy Station Siting

During last week’s record-setting European heat wave, Germany’s previous record of 40.3C was impressively shattered by the measurement station located at the northwest city of Lingen, near the Dutch border, some 50 kilometers from where I live. The German DWD weather service and media loved it!

Controversial siting

Yet, controversy now swirls about the new record setting measurement since it has come to light that the measurement is fraught with some considerable siting issues.

Lingen Weather Station seen from Google Earth at 52.518066°N 7.307508°E – Located by A. Watts

As the photo published by T-online here shows, the station is located right near a DWD office building, is shielded from the wind by grown trees and is located not far from a public swimming pool.

Meteorologist Michael Theusner told t-online.de:

“The monthly average of the daily highs in Lingen has been deviating more and more upwards from the average of the highs in Lower Saxony since 2010.” The station has become increasingly shielded and thus tends to heat up more.

Swiss veteran meteorologist Jörg Kachelmann wrote the extra heat possibly could be heating the station by up to another 3 degrees!

DWD accepts overheated reading

Germany’s DWD national weather service has even confirmed that the station’s siting is no longer adequate and that a move to a new site had been already long planned. But despite the acknowledged poor siting, the DWD went ahead and confirmed the reading as valid. The 42.6°C reading now stands as Germany’s new all-time recorded high temperature, no matter how questionable the reading may be.

Valid? How does Lingen compare to other temperature stations located nearby? I did a check.

Fifty kilometers to the east of Lingen where I live (Quakenbrück), my home thermometer showed a high of 38.2°C. That’s unofficial, of course, but it made the Lingen reading look suspicious. So I decided to compare Lingen to the other official stations nearby to see if their readings were as hot as Lingen’s.

The surrounding readings do indeed confirm meteorologist Kachelmann’s gut suspicion. Lingen readings are suspiciously 2 – 3C hotter than those of its neighboring stations.

What follows is a chart depicting the readings recorded by the Lingen station over the past past week. The DWD itself stated that the mercury in fact reached 42.6°C on Thursday (Do. 25.07)!

Chart: wetter24.de

Now looking at the Nordhorn station, located some 20 kilometers away, here the mercury climbed to 40.9°C, which is 1.7°C below the Lingen reading:

Chart: wetter24.de

At the Meppen station, also located some 20 km away to the north of Lingen, the mercury reached 39.2°C, a far cry (3.4°C) from Lingen’s maximum reading:

Chart: wetter24.de

At the military base in Diepholz, some 65 km to the east, the high on Thursday reached 38.7 degrees, i.e. almost 4°C below the Lingen reading!

More than 2°C hotter than surrounding stations!

A summary of all the temperature readings recorded at Lingen compared to those of six nearby stations for the past five days, July 23 – July 27:

On every single day, Lingen handily beat its neighbors by at times large margins.

Lingen 2.6°C hotter than adjacent stations

On the record-setting date of Thursday, July 25, 2019, the mean of the six neighboring stations listed in the table was an eyebrow-raising 2.6°C below the Lingen reading.

All the stations cited around the Lingen station all share very similar topographical characteristics, and all are located on the north German flatlands, and thus comparable.

No doubt the reading at Lingen is accurate. But it looks like the siting of the Lingen station is causing overheated conditions.

O/T, but what’s up with the current melt shown at DMI’s website occurring in Greenland? Typically this kind of abrupt change reflects equipment malfunctions, but I’ve heard no word of that. On earth.nullschool.net it appears that there may be a dome of high pressure over southeastern Greenland (based on wind patterns). Thoughts?

My understanding is that it’s the air system that caused Europe to get so hot which has moved up over Greenland.

Those differences are in line with BBC Weather forecast which gives 2 or 3 degrees as the difference between town and country temperatures in these conditions.

Exactly the same thing as last month’s famous high in Gallargues-Monstrueux . A class 3 station similarly situated near water ( which would tend to reduce temps in case of a south wind ) and near a massive road haulage depot with acres of nice black bitumen and 1000 m^2 of steel sheet roofed warehouses …. up wind of the prevailing wind on the day in question.

Similarly, the national weather service dispacted someone to check the station and concluded that since the wind was not from the south , the water ( the only feature offically recorded as a potential problem ) was not a factor on this day and similarly “validated” the reading.

A professional met officer sent specifically to check the site could not have been unaware of the lorry park but conveniently chose to ignore it on the pretext that it was not recorded as a potential cause of bias.

who would want to miss the opertunity to get in the Guiness book of record temperatures ?!

So like Germany , France has a new FAKE “hottest ever” temperature on record. Duly “validated” for media to freely use and misrepresent the “climate crisis”.

Thanks to Pierre Gosselin for checking out the German record site.

Can’t really call this a “Fake Record”, since it was entered following established rules. At best it’s a inaccurate record which does not reflect natural weather, but only a single site in an unnatural setting.

But you have actually made it somewhat useful, in that you have established that there is at least a 3C UHI effect in that area. If one were to create individual corrections for urban sites by using nearby rural sites, one could then correct the raw data to be more accurate. It would be interesting to see what the result is, but it’s simpler to just use well situated rural stations to determine natural temperatures. I seem to remember that has been done for limited areas and resulted in a warming trend of about…1/2 (?) of the current reported trend.

So assuming my memory is accurate, up to 50% of the current warming is explained by UHI.

August 1, 2019 12:34 pm

There is a general problem with these supposedly record temperatures throughout the UK, and all for the same reason UHI!

Ironically, the BBC regularly confirms this in its daily weather forecasts. The weather man or woman quotes the UK temperatures for the UK as indicated on the chart behind them, and then very often says,” but in more rural areas the temperature will be a degree or two lower!

Yet these temperatures are as recorded on the same weather stations which which are the recorded temperatures used to “substantiate” ongoing CAGW/Climate change and their continuous demands for CO2 emission reductions.

Rural areas cover far more area of the UK than urbanised areas. Urban areas are also increasing due to urban sprawl and new housing developments in rural areas That means that weather stations set up years ago in what were more rural areas are now often in urbanised areas and suffer the same UHI effects. There is therefore a varying but significant effect on supposedly recorded average temperatures.

The temperature differences quoted by the BBC in rural areas confirm that average temperatures are actually significantly lower than those reported, massively more than the target 1.5 degrees C temperature rise in 80 years that we have and are still paying for on man-made CO2 emission reduction programmes.

I seem to recall, but can’t find the source, that the temperature at Victoria’s Diamond Jubilee Naval Regatta at Spithead in 1897 as 100 degrees , i.e. over 38 degrees centigrade – the same temperature just recorded by the Met Office and reported as the highest ever!

Climatology as a science is so bad it is comparable to the old time alchemists trying to turn gold into lead. (1) Poor quality unreliable data. As near as I can tell most of the temperature data is so unreliable it needs to be tossed out. It’s like if Issac Newton had realized that gravity pulled the apple down and then decided that for every force there must be an equal and opposite counter-force so if apples fall down then pears and bananas must fall up. And then made up the data to prove it. (2) A simplistic one variable hypothesis trying to explain what we already know to be a poorly understood multi-variable chaotic system. (3) The influence of the single biggest variable – the sun – is poorly understood.

Just imagine if all the sciences were of the same high quality of this climatology stuff – “Hey Joe, I’m going to go make a a new batch of them thar nuclear bombs this morning.” “OK Boobsie, I’ll go put my ear plugs in.”

…and then to boot, there are confirmation bias, plain old fraud, and the endless, insistent, desperate need for novelty no matter how utterly pointless and useless – the unavoidable result of turning out thousands upon thousands of mediocre science grads every year. My stepfather of blessed memory (psychologist and psycholinguist who helped design the ergonomics for the lunar excursion module) used to joke about it all the time, citing his favorite,
“The Left-turning Tendency of the Dancing Ground Squirrel.”

Now of course it would have to be “Dancing Ground Squirrel under threat of extinction due to climate change” and immediately distributed to all social media and news networks.

…the old record in Germany was 40,3°C and was beaten 25th July by 0,2 °C. The reading of the station on the NATO-Airport Geilenkirchen was also confirmed as ‘new heat record’ by the DWD, ignoring the fact, that this station sits a few meters next to the runway and is not even a part of the official weather network in Germany.

UHI effects in rapidly growing cities and towns and poorly sited meteorological stations which overheat are the bread and butter of everyday Global Warming/Climate Change Alarmism. There is no urgency shown to investigate these areas as the results could be very antithetical to the Cause of Gaia.

I did some checks for weather stations on the Dutch side of the border.

I checked 5 stations West of Lingen. The results for the 25th of July 2019:
Emmen, 40 km to the NW: 38.7 at 17.02
Sleen, 44 km to the NW: 40.1 at 18.02
Wierden, 53 km to the WSW: 38.9 at 12.17
Hengelo, 48 km to the SW: 40.9 at 17.02
Losser 38 km to the SSW: 41.5 at 15.02

Average of the 5 stations: 40.0 degrees, again 2.6 degrees below the Lingen reading.

You see in the Sat-Image the hot spot of Lingen (in case you know where to look).

https://www.esa.int/spaceinimages/Images/2019/07/Extreme_heatwave

So UHI has an influnece here – and still the french records Frncoise mentioned are not in Urban influnce.

And some of the German station surpassing the old record on the same day are as well closer to rural than to urban character.

And furthermore: just look at the distribution for high temps over time in Germany: these increse in frequency and in number of stations (on the ame day) .

All in all: the lingen value can be disputed, the heat records hardly can.

WR: The link you give is for the day after (!) the record breaking event: for the 26th of July. The scale is not appropriate to find back Lingen. Besides the fact that the time mentioned (10.44 AM) is not very well suited to find a record temperature, there are locations visible in Germany that are warmer than near the German/Dutch border.

Hi F.Ketterer, OK, thanks. But in the hires version I still don’t see Lingen as being hotter than the whole German-Dutch region where I also found my Dutch stations in. So I still think the measurement in Lingen is a very local measurement not reflecting the temperature of the region. Perhaps the soccer field played a big role, mentioned by Gerard: https://wattsupwiththat.com/2019/08/01/poorly-sited-weather-station-leads-to-a-fake-record-high-in-germany/#comment-2759207 .

“Average of the 5 stations: 40.0 degrees, again 2.6 degrees below the Lingen reading.”

I much appreciate the accuracy of your comments, but sorry: this here is absolute nonsense.

Either
– you compare the Lingen result with the highest one you found in your Nederlandse corner
or
– you compare your average with that of Lingen together with 4 nearby stations.

Bindidon, I understand your way of reasoning. I wanted to check whether Lingen was an outlier and that still seems to be the case. And the more Lingen diverges from the average, the more suspect the Lingen result is.

August 1, 2019 3:50 pm

somebody with access to all of the raw data should do a study of the average temperature departures of the properly-sited long term rural stations against the average temperature departures of the no longer properly sited long term urban stations. I’m willing to bet that the urban heat island effect becomes glaringly obvious.

There’s a good paper here: http://oprj.net/articles/climate-science/34

To summarise: there are only nine stations globally that are both rural and have over 100 years of data and all of these have problems (stations moves and one was inside a building).

In conclusion: it is pointless using ground station data which is so overwhelmingly contaminated by urban heating that it is utterly meaningless for long term temperature trends.

Our famous KNMI had an overenthusiastic and wrong Twitter message: The former record of 38.6 degrees Celsius would have been broken by a 41.7 degrees in Deelen. https://twitter.com/KNMI/status/1154362572138852354 . The KNMI had to be corrected by weather amateurs. They saw what the KNMI did not check: a rise in temperature from 38.3 to 41.6 in less than 10 minutes – impossible.

The KNMI had to correct the former message: https://twitter.com/KNMI/status/1154372338806398976 (in Dutch). The measurement in Deelen was not valid.

Both KNMI and DWD are member of the World Meteorological Organisation (WMO). The DWD president even stands for WMO presidency: https://www.dwd.de/EN/Home/_functions/aktuelles/2019/20190517_candidate.html

It has been the WMO together with the United Nations Environmental Program (UNEP) who created the IPCC in 1988:

“The IPCC provides regular assessments of the scientific basis of climate change, its impacts and future risks, and options for adaptation and mitigation

Created in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), the objective of the IPCC is to provide governments at all levels with scientific information that they can use to develop climate policies. IPCC reports are also a key input into international climate change negotiations.”
Source: https://www.ipcc.ch/about/

It has been the IPCC (again: founded by the UNEP and the WMO) that created the predictions about climate. WMO’s members KNMI and DWD are very eager to accept and present new high temperature records, while their previous role was the presentation of perfect measurements that could be fully relied on. Their role seems changed.
