Is the BOM manipulating temperature records?
 
This has been reported by Chriss Smith of 2GB but I have noticed it as well. I frequently monitor the temp on the BOM website, especially on cold nights so I have seen it myself.

The Golbourn AWOS reports the real time temp of say -10.5 deg C. I see it sitting at my desk. several days later i look at the temperature records and see that the lowest temp on that day has been adjusted to something like -9.0.

Can the BOM be trusted for aeronautical data?

That ties well with the lack of credibility of the temperatures that are used re runway length. Aircraft may very well being loaded at lesser weights to suit the corrupt BOM temps. A huge cost to Australian aviation.

Certainly a good case for the government to launch an investigation.

This thread is sure to bring the climate-change skeptic/conspiracy nutters out from under the wood pile.

What possible motivation would BOM for manipulating weather observations?

I've met a few BOM staff over the years and they all appear to have been very serious professionals working to do the best job possible.

If unsure - then test it !!!

Go down to Bunnings, spend ~$100 to buy a portable weather station, locate it near the BOM weather station in question and publish the results. Questions answered.

Peterc005...I trust the BOM to maintain a database as much as I trust a CASA FOI to understand a p-chart.

Blah, blah, blah. I'm a crazy nut bag who believes the BOM, NASA and every reputable scientist in the world is in on a climate change conspiracy.

Perhaps peterc005 can tell us all about this then...

"...RATHER than admit that temperature dropped to a record low -10.4 degree Celsius on the morning of Sunday 2nd July at Goulburn, the Bureau of Meteorology has come-up with yet another even more absurd story.

Responding to a letter from Josh Frydenberg, the Minister for Environment and Energy, Andrew Johnson, CEO and Director of Meteorology, has claimed the weather station malfunctioned. Previously the Bureau claimed that they had placed new limits on how cold it could get at Goulburn..."

peterc005 1st Aug 2017 04:16

As I said above, if you have concerns about BOM data buy a weather station to take your own measurements to compare with the BOM.

So far the only argument is an unsubstantiated anecdote about weather data. Show us the facts.

Flying Binghi 1st Aug 2017 06:01

The BOM initially provided the "facts"...

“The correct minimum temperature for Goulburn on 2 July, 2017 is -10.4 recorded at 6.30am at Goulburn Airport AWS… The Bureau’s quality control system, designed to filter out spurious low or high values was set at -10 minimum for Goulburn which is why the record automatically adjusted.”

Then different 'facts' were provided to the minister...

...“the AWS at Goulburn stopped recording when the temperature fell below -10°C.”...

So which of these 'facts' provided by the BOM is correct ?



"...In short, after initially recording -10.0 in the CDO dataset, this was changed to -10.4 three days later following a blog post ( Bureau Erases Goulburn Record Minimum), an outcry on Facebook, and enquires from prominent journalists..."

Ultralights 1st Aug 2017 06:34

was the weather station at YLGB the official station that the data is taken from? i know at Moorebank, the temperature is taken from Holsworthy airport, well away from the heat island effect, and can vary by quite a few degrees.

compressor stall 1st Aug 2017 08:36

I can't talk about the Goulburn incident, but there are a vast number of private weather stations that feed into WUnderground. If you look at them, you will see definite trends across fairly small areas. Local microclimates can play a very big part in climate records.

There have been occasions where massive uproar amongst climate deniers has been caused after temperature corrections have been applied to a data set where the recording station has been moved. Moving a recording station then correcting the temperature bias is sound science, not a conspiracy.

Of course the climate is changing.

In the 70's there was the threat of an ice age.

That's changed...

advo-cate 1st Aug 2017 11:42

Well lets get back to facts here. There has been a series of unexplained changes to weather data by the BOM. The most recent was the Rutherglen data set which were compared with and "homogenized" with data from around 1000 km away.

Well??? hows that??

And back to aviation and the TTF at Adelaide that was wrong 4 years ago and two 737's end up at Mildura with next to no fuel.

BOM fail, but no SR's issued in the "slow to develop" ATSB report.

Well??

bolthead 1st Aug 2017 11:51

You'd think with these 'homogenizations', some would be homogenised up, and some down. Does anyone know a rough percentage of which way they went?

Derfred 1st Aug 2017 12:43

Correct, advo.

My Airline is constantly issuing additional weather holding/alternate fuel recommendations because they don't trust the BOM forecasts.

Which is weird, because the conspiracy theorists say that the BOM issues overly optimistic forecasts because they are pressured by the airlines to do so!

Fortunately pilots still get to order fuel without influence.

peterc005 1st Aug 2017 12:46

BOM are "Manipulating Temperature Records"?

They are explained, if you ask them.

Anyone who has had to deal with raw data knows that it can have all kinds of problems. This holy grail of pristine raw data that needs no management is a pie in the sky dream.

Look up the BEST project. A group of skeptics with some actual brains went ahead and independently rebuilt the temperature record using the same raw data. They came up with the same results the regular climate scientists came up with. Result, BEST called it a day and agreed that the climate is warming. There was no need to continue what is a lot of hard work to come up with the same results as mainstream scientists.

Marohasy is just a fringe nutter. You can safely ignore her and her small army of amateurs.

underfire 2nd Aug 2017 02:13

FWIW, BOM has been trying to get out of the AWOS business for a long time. Unfortunately, due to the contractural obligations, its is likely not going to happen.
What aviation is saddled with is aging, out of date equipment held together with bandaids hoping they can unload the obligation.

A few airports have gone out on there own and secured 3rd party AWOS systems, especially the mining operations.

Seems many without the facts think just a hand-wave to some link is all that is needed. Perhaps a hand-wave to any religious book then makes it true...:hmm:

RickNRoll made the claims. RickNRoll can provide the excerpts or information to back up the claims.

Interesting. I note that well over half, likely three quarters, of the funding for the Australian greeny industry comes from the mining industry. I don't see much support from the greenys for mining..:hmm:


Continuing... I mighta found this skeptic RickNRoll mentioned. Or maybe not...

"...No skeptic I’ve met said that “… carbon dioxide from burning of fossil fuels will prove to be the greatest pollutant of human history. It is likely to have severe and detrimental effects on global climate.” (Richard Muller, 2003). So perhaps he became a skeptic later? Not so much. Richard Muller, 2008: “There is a consensus that global warming is real. …it’s going to get much, much worse.”

The defining mark of a skeptic is that they never believe simply because there is a “consensus”..."


Muller-the-pretend-skeptic makes three claims. He?s half right on one. « JoNova

No, I didn't think so..:hmm:

It is interesting when you take a look at the people involved in the BEST project and then have a look at the names involved in the Muller & Associates company: Our Team | Muller & Associates. How many are Listed on both sites... five, six.......

So this little diversion to the BEST project has shown us the climate 'industry' write large..:hmm:

Also, the BEST project did not do any audit or due diligence of the BOM temp records so it is a bit silly to attempt to use it as a device to somehow validate the BOM temperature records.


So back to the thread subject...

"Bush meteorologist Lance Pidgeon had hard evidence it was cold near Goulburn in the early hours of July 2 this year because his cold water pipes froze, bursting in the wall and breaking the toilet.

To be certain, Pidgeon checked the Bureau of Meteorology (BoM) website and saw the temperature had plunged to minus 10.4C.

“But then I saw something truly bizarre,” Pidgeon says. The temperature recording on BoM’s website adjusted itself to minus 10C and then disappeared from view..."

You feeling okay binghi? Your posts are even less coherent than usual.

The BEST study represents everything a true skeptic should appreciate. You have really had to scrape the bottom of the barrel in an attempt to convince yourself the conclusions of their study are meaningless.

There are none so blind as those who cannot see!

Chuboy, I think you will find some posts i made in pprune way back when the BEST project first got started. The concept were good though it soon turned to mud when the first 'research' were put out to the media without any peer review. All well covered at WUWT: https://wattsupwiththat.com

I'm still waiting to see from RickNRoll how the BEST project actually relates to the corruption displayed by the Australian BOM. Were the BOM/CSIRO met records actually audited by the BEST project. If not, it is irelavent to this thread - perhaps a diversion of desperation..:hmm:

The Australian BOM corruption has even got the attention of President Trumps main news source:

"...The BOM has now been shamed by media investigations into ordering a review of its procedures. But it has yet to provide an explanation as to why it made these “adjustments” in the first place.

These “adjustments” seem to go only one way. The BOM is perfectly happy to record and announce it whenever Australia’s temperatures hit record-breaking highs. But when the temperatures reach new lows it’s a different matter altogether.

For some strange reason that the BOM has been unable to explain, when temperatures go below a certain point it either deletes them as if they had never been – or it enters them into its records at higher temperature than the one actually recorded by its thermometers..."

Oooh! that looks like a really high-brow blog there peter. I can see where you get all your information, from with an Astrology guide amongst the top articles!

To quote Robert Heinlein
"A touchstone to determine the actual worth of an "intellectual" - find out how he feels about astrology."

But then again, to someone who thinks that precision scientific instruments can be found in Bunnings for circa $100 bucks, I suppose anything is believable.

De_flieger 3rd Aug 2017 07:37

I can see why you wouldn't want to take sites that include any references to astrology seriously, so anything published by news.com.au, https://www.news.com.au/lifestyle/horoscopes like the Daily Telegraph No Cookies | Daily Telegraph and Courier Mail No Cookies | The Courier Mail can be ruled out on the same grounds. Good to know.
