The Heathrow Temperature Data That The Met Office Tried To Withhold

Readers will recall that when I asked for the temperature data at Heathrow for 1st July, I was told it would cost me £75 (+ VAT!!). The next day, however, they published this graph, showing a considerable spike.

 

Thanks to Willis Eschenbach’s excellent analysis at WUWT, I noticed that the data I had requested had actually been provided FOC to Carbon Brief, a political blog set up to promote the decarbonisation agenda. Carbon Brief, with the help of advice from the Met Office’s Mark McCarthy, then used the data to attempt to prove the assertion that it “woz the sun wot done it, onest guv”.

 

So, let’s take a look at the data, which the Met Office were so reluctant to hand over to me.

We find that the temperature at Heathrow jumped from 35.8C to 36.7C in the space of two minutes. According to Clive Best’s analysis, a Boeing 747 landed on the runway just to the south of the temperature sensor at 14.13, just as the temperature peaked. [UPDATE – We believe that the airline times are BST, and not GMT, as the Met Office have used. Clive is rechecking this]

Also note that there was a subtle wind shift from from the SE to S, from 14.06 to 14.12, just as temperatures picked up.

 

Meanwhile, the Met Office have two serious questions to answer: 

 

1) Why were they so reluctant to provide this data to me in the first place? 

2) Why are they so keen to help the Carbon Brief with their propaganda?

 

 

 

Is it really possible for a bit of sunshine to increase temperatures by 0.9C in two minutes? Or 1.6C in five?

    So that’s get this clear, the Met Office, a publicly funded organisation gives out info. for free to some people and charges others. This must go against Civil Service rules, or at least it would have done when I was a a civil servant.

    UK Met shown not just wrong, but also duplicitous and in cahoots with pure propagandists. Well done. Very well done.

    Maybe Carbon Brief used some of their Exxon funding to buy the data.

    My impression is that in the good old USA, they don’t need any reason to fudge the data, they just fudge the data. How else do you account for an average of 8 degrees difference between the Reagan National Airport high temperature readings and that of the max/min thermometer sitting out in my 10th story balcony, in shaded open air, less than 15 miles away?

    When I bought the max/min thermometer, I did so with no preconceived notion or any attempt to cool bias the readings. I also checked the thermometer with two reliable indoor thermometers and it appears dead accurate.

    I am surrounded by woodlands, near no large body of water.

      10 stories up should make a big difference in temps. However, it is also common to commute from the suburbs into DC and see several degrees of temp increase along the way. There is no question that DC (and Washington National) suffer from a significant urban heat island effect.

        But I think you would agree that siting is extremely important, which gives those with an agenda a means to manipulate temperatures. Plus UHI should not make a huge difference with max temperatures, much more so in the early morning during the normal commuting time.

    Have you contacted them with the above questions ?

    Paul says: “Is it really possible for a bit of sunshine to increase temperatures by 0.9C in two minutes?”

    Q = Cp * m * dT.

    That should answer your question.

    Paul this collusion which has been suspected for a considerable time needs maximum national & international media publicity and must be drawn to the attention of key government figures that the credibility and functionality of the Met Office is becoming a disreputable organisation under the control of extreme climate change activists.
    Their web site statement below endorses this fact…

    Climate change

    ‘Climate change has become an increasingly important issue and our research continues to create an ever clearer picture of how it will affect the planet and our lives. This plays a vital role in providing evidence to support climate predictions which show the planet is now locked into at least 2 °C of warming and rapid reductions in greenhouse gas emissions are required to ensure this does not rise further for future generations’.

    ‘With this in mind, we have been providing tailored advice and services for a range of clients to help them begin adapting to the consequences of climate change. This has included projects focusing on defence, transport, energy, water supply, defence, flooding, health, and a host of other issues. We will continue to use our expertise to further understanding of climate change, as well as offering advice on how to mitigate the risks and adapt to its consequences’.

      ‘tailored advice.’

    The analysis is, of course, interesting (and potentially disturbing), but like you and other commentators here, the really disturbing issue for me is why a publicly funded body is reluctant to provide info to some people except at a charge, while providing it to others for free.

    I shall keep an eye on this thread to see if they provide an answer to your question tomorrow, but I suspect the response will be either silence or something disingenuous.

    Thanks, Paul.
    Corruption is what a bit of sunshine might uncover.

    Why should the Met Office wish to give you the data, as to do that would open the can of worms of sunshine causing warming.

    Great work, Paul. They will not like this one little bit.

    Paul,

    I have re-checked the Heathrow landing data for the North runway during the ‘record’ heat spike at ~14:15 GMT on 1st July. Two BA 747-400s landed within 2 minues of each other. The first BA 272 from San Diego landed at 14:13 GMT and the second BA 274 from Las Vegas landed at 14:15 GMT. It is likely that such heavy aircraft would have exited the runway directly in-line with the Met Office station. That equates to 8 Rolls Royce Jet engines pointing at the station within a 2 minute period enhanced by a SE wind blowing directly along the exit lane.

    Yes Sterling stuff, but isn’t it a pathetic state of affairs where individuals have to hold major Govt institutions to account
    Who has embedded these rotten apples policies in places which should be operating with the highest scientific integrity ?

      Completely agree. The deliberate lying that has become all-but commonplace in almost all ‘climate’ issues is a damning indictment of the fundamental weakness of their position. They cannot get away with their lies forever though: truth will out.

      • July 21, 2015 4:19 pm

        after our viisit to room 101 we will surely all realise that the ministry of truth does not lie. will probably meet you all there soon, before Paris i suspect.

    Paul, can I suggest you ask the MO for the data for 11Aug2003 for the hours between 1200-1500 UTC.

    I have been collecting hourly data for 27 UK locations since Oct1998. The hourly data for the above date shows 36/37/37/36 respectively.

    I wonder if they will be forthcoming?

    • July 20, 2015 9:51 am

      They are only claiming a record for July at Heathrow.

      I’ll ask for the info anyway

      Thanks

    Happened in Sydney where the temp rose 0.9C in 4 mins and then dropped 1.1C in the next six minutes. This resulted in a new max record for Sydney beating the old 1939 record. More sensitive therms than the old M & A therms would result in this happening.

      The AWS at Observatory Hill recorded a maximum of 45.3ºC, the same temperature as 1939.

      There has NEVER been a satisfactory explanation where the extra 0.5ºC came from.

      It is a FABRICATION.

      Anyway.. same temp as 74 years earlier, with all the Sydney UHI effect, and the hot westerly blowing across what used to be outer suburb farms, and is now wall to wall houses, picking up heat instead of dropping it.

      Nope, that is not GLOBAL warming, that is UHI effects and data manipulation.
