GOULBURN is a town, to the southwest of Sydney, known for its maximum-security prison. It is also a place, that by Australian standards gets quite cold. Temperatures have been measured at the airport since 1988, and the lowest temperature ever record in July is officially -9.1 degrees Celsius.
In fact, Sunday morning this record was smashed!
It got down to -10.4 degrees Celsius, at 6.17am on Sunday 2nd July. This was the official Bureau recording for Goulburn.
Except, the Bureau has since erased this measurement.
According to the Bureau’s own rules, the coldest temperature record during a 24-hour period to 9am is recorded as the minimum for that day. So, for Sunday 2 July the carry-over minimum should be -10.4 degrees Celsius. But instead the summary documentation shows -10.0. There is now no public record of -10.4 degrees Celsius.
I would have the managers at the Bureau put in the Goulburn jail.
Update 9pm Tuesday evening
So, the Bureau has now acknowledged that it really was -10.4 degree Celsius at Goulburn on Sunday morning, and corrected the ‘Daily Weather Observations’ page for Goulburn.
However, the Bureau has so far not updated the key CDO Online database, the official record of temperatures for Goulburn airport. This is the dataset used to calculate regional, national and global temperatures. Rather than replace the bogus -10.0 degree Celsius with the correct -10.4, they are leaving a blank. Not good enough.
Update 6am Tuesday 10 July
The following screenshot is provided as further evidence that the Bureau’s ‘quality control’ changed the actual reading of -10.4, to -10.0 which was then entered into the CDO database. After protests the -10.0 value was removed and no reading recorded. After more protests, the correct value of -10.4 was inserted. This is unprecedented.
It was not until two days later that the correct value was inserted, as shown in the following screen shot – taken this morning.
Neville White says
Are you saying they make stuff up?
David Jaques-Watson says
Have you asked the BoM themselves about it?
So, I posted this here, and alerted a favourite journalist. I’ve been told that a request has been made by this journalist for clarification from the Bureau… for justification for what has been done.
Bob Fernley-Jones says
If the BoM can verify that the original value was wrong, I wonder how they could determine what it should be.
I would have thought that that the correct thing to do, but only if they could prove it was wrong originally, would be to replace with no data, otherwise it should not be altered.
James Doogue says
This is just another piece of evidence which proves the BOM are adjusting the official temperature record to show a fake warming. It serves their climate alarmist narrative which they are dedicated to and which carries over to the CSIRO who have lost all scientific inquisitiveness on climate change.
Warren McLaughlin says
This ultra LOW is significant since so much has been made of “Warmest day ever” posts that were intended to sway people in accepting the BoMs findings about continued warming trends.
Jen, the Rutherglen story clearly showed the BoM were prepared to fudge the facts; and now they’re doing it again!
Well, it cant be rounding down from -10.4 to -10.0, as the Saturday minimum, Sunday maximum and Tuesday minimum all show the first decimal.
A check of the record today (Tuesday) shows -9.7 at 6.00am, and -10.0 at 6.30am. The 6.17am recording of -10.4 is missing.
But quelle horreur!, from 5:00am to 7:30am they show individual recordings at intervals as little as 3 min (5.08am, 5.11am) to a maximum of 14 min (7.00am, 7.14am).
Strangely, the only recording missing is the 29 year record July low at 6.17am. It creates an anomalous gap betweeen 6.00am and 6.30am.
A reasonable person could only conclude that once measured, the 6.17am recording was manually removed as to create a false impression of the minimum for the day.
Also note that the Canberra temperature at 6:29 AM on that top screen shot is recorded as being “- 8.0” and “- 8.2” within the same minute. Lance Pidgeon.
Outright official corruption.
Robert B says
This not half as bad as what has happened before. I’ve pointed out a few times this anomaly
The record coldest for August was -2.4 until 2014. It reached -2.3 for three days, stubbornly refusing to break the record. BOM throw out maximums that are the same for two days in old records, assuming a mistake and its usually temps above the average. For some reason, two days in a row must be a mistake but three is not implausible.
I lived nearby at the time and while I can’t tell you that the minimum temps were definitely different, the amount of frost differed a lot and that usually means significantly different min temps. My guess is that the second and third days were colder than the forth and the nearby Lake Victoria station backs that (has an aug min 0.8 higher)
They were found out this time, but how many other instances of data manipulation have been unnoticed? A very large number, I would suggest.
Keep up the good work Jenn. At least people like you and Tony Heller are sacrificing your time and energy to call out this endless fraud. We appreciate!
Geoffrey Williams says
Well done Jennifer for highlighting this case of temperature manipulation by the B.O.M.
It is a disgrace that the people charged with the responsibility of monitoring Australian temperatures cannot be trusted to do so in a competent and honest manner.
Regards Geoff Williams, Sydney.
I think we are seeing in real time how religions select their holy texts.
A good example of adjustment.
The raw accurate temperature records are a national asset and should be treated that way. They should not be manipulated & kept in a pristine state. Copies can be made and analysed but the original should remain as recorded as a matter of law.
Harry Twinotter says
I do not understand what point you are trying to make here. It seems you are implying a conspiracy involving the BOM on the basis of a single, unquality-controlled temperature measurement.
Don Andersen says
I’ve seen this type of “error” before and I think this is a fault in BOM procedures, not anything sinister. It’s possibly to do with the the fact that “live” data is published for individual stations at half hourly intervals. When station downloads are complete, there would be Tmax and Tmin figures in the record, requiring an update.
PS: Australian temperature records are in an appalling state but i think this one is explainable.
Don and Harry
You are in error.
The value of -10.0 went through and was inserted into the CDO online database. So, quality control resulted in the correct value of -10.4 being deleted, and replaced with the value of -10.0.
This error was not corrected until a journalist pressed the Bureau for an explanation.
If you would like me to post more screenshots, to show the -10.0 showing at the CDO dataset… let me know.
Harry Twinotter says
You are making one assumption after another and not showing any evidence that you are correct. But I do understand you run a Conspiracy Theory blog, so be it – I do not expect you to have high standards despite the fact you are expecting high standards from the BOM.
Did you or the journalist have a copy of the response from the BOM? I am interested in that.
I do have a copy of the response from the Bureau. It states that when a temperature at Goulburn is recorded as less than -10.0 degree, it is corrected to -10.0 degree. Jennifer
The tinfoil is worn by the reactionary climate true believers. Ignorant dismissal of skepticics is one of their main means of expression.
Harry Twinotter says
It would have been nice to see a copy of the response from the BOM. I understand they actually posted about the -10.4C figure on Twitter that morning, highlighting how unusually cold it was. Not much of a cover up.
I’ve quoted some of the response in my article just now published by The Spectator here: https://spectator.com.au/2017/07/price-of-electricity-is-rising-not-sure-about-temperatures/
What a story! Somebody decided a priori what the possible temperature range can be, causing a warming bias. And, the good part is, we have no idea how often these biases have been active and since when. They are opaque.
