Albany robbed of its coldest ever April day, BOM adjusts temp up 15 degrees C?!

Jo Nova has the latest example of temperature shenanigans in Australia:



Friday April 19th set more records than anyone realized. Not only was it the earliest recorded snowfall at Bluff Knoll, but it was also the coldest ever April day in Albany and many other towns in south-west Western Australia. It may also be the largest single day temperature mystery I’ve ever seen in the official “raw” data.

Days like the 19th are extremely unusual in Western Australia — it’s a state that often doesn’t get any snow all year and when it does, the length of the entire snow season is measured in hours. So you might think the million-dollar-a-day Bureau of Meteorology would be paying extra attention. Instead it appears they have lost that day’s data in Albany, despite having two thermometers there to record it. One station is in the city itself and there’s an official “expert” ACORN station at the airport about 10km away.

Luckily Chris Gillham, unpaid volunteer, was watching the live half hour observations roll in at and saw that thermometers at the airport recorded a maximum of only 10.4°C at 11am that day, which he remarks is the lowest April maximum the BOM has ever recorded there. Strangely, the 10.4°C seems to have disappeared. Somehow, the BOM has estimated that April 19th in the city of Albany was 25.1°C on Friday April 19th, which is what is now entered as “raw data” in their Climate Data Online. This is despite temperatures in almost all the surrounding towns being similarly low, and often lowest ever records (for April) as well.

This single day’s omission is so large, it raises the monthly average of Albany Airport by 0.7°C— that’s equivalent to 70 years of “global warming”. Chris reports below that the airport thermometer was also missing four days following Good Friday, which were reasonably cool (according to the City thermometer). He estimates that if the airport thermometer had worked, the official monthly average would have been nearly a whole degree, or 0.9°C cooler than what was officially recorded. (Jo, meanwhile, wonders if any planes took off at Albany Airport over Easter and whether they missed having weather data?).

Full story here.

    You pose me a problem, Mr Homewood. Into which bookmark folder should I put the link?

    I don’t normally put Goebbels Warming stuff into the folder on Scientific Lies and Errors because it would utterly dominate the folder. Maybe I should open a folder on Hard-to-explain climate idiocies?

    Fraud in plain view. Yet another example of the awful slippery slope that ensues when ideology replaces science. The response from the MSM – complicit silence.

    ‘Climate Data Online’

    Language mashed into meaninglessness. There is no such thing as “climate data.” Calling weather data “climate data” is goofy, and of obvious political origin.

    It needs an official inquiry and a few heads rolling (pour encourager les autres).

    Cheating is getting more blatant as the forecasts are getting more wrong.

    Talking of stealth editing shenanigans yesterday we spotted that a Smart meter tweet was illegal
    cos of the way it embedded a BBC link-graphic which included a political placard.
    and ASA rules prevent political messages in adverts
    (That’s why the agency wouldn’t carry the IcelandSupermarkets/Greepeace palm-oil advert).

    Anyway today after 3 days the Tweet graphic has been changed, not cos of us,
    but cos in one of their many stealth-edits the BBC had already changed the graphic and eventually Twitter’s cache had caught up.

    One side question that came up is why did BBC drop “by 2050” in the link title ?
    : UK ‘can cut emissions to nearly zero’ by 2050
    to : UK ‘can cut emissions to nearly zero’ …..
    (yet the page text does keep that claim)

    A date limited twitter search does show
    people and news stories talking about the cold that day

      There is a thing with squalls that if the squall drops and the sun comes out
      ..the temperature can shoot up for a few minutes

      Were BOM thinking about Earth Day PR ..April 22nd ?

    If they destroy their own temperature record credibility, they can’t then claim it has any meaning.

    The only solution is to do what business friends of mine do – when it comes to temperature, gas, electric, water usage – take your own daily readings and don’t trust any agency or utility company.

    Time to bring the Carry On franchise out of retirement.

      Carry On Regardless (or has that one been taken?)
