The Bureau of Meteorology, I mean – they wouldn’t manipulate actual temperature readings to fall in line with the climate change alarmism narrative, would they?
In today’s issue of The Australian, Graham Lloyd, Environment Editor, describes the case of some (inconveniently ?) low temperature readings that were excised, temporarily, from the Bureau’s published data. They were restored later as a result of either,
The article is: Bureau of Meteorology opens cold case on temperature data, and commences:The Bureau of Meteorology has ordered a full review of temperature recording equipment and procedures after the peak weather agency was caught tampering with cold winter temperature logs in at least two locations.
The bureau has admitted that a problem with recording very low temperatures is more widespread than Goulburn and the Snowy Mountains but rejected it has -attempted to manipulate temperature records.
The bureau’s chief executive, Andrew Johnson, has called for an urgent review and the immediate replacement of recording equipment at a number of undisclosed sites. The action was outlined in a letter to federal Environment Minister Josh Frydenberg and follows weeks of turmoil over why data showing minus 10.4C readings at Goulburn and Thredbo went missing.
Bush meteorologist Lance Pidgeon blew the whistle on the missing data after watching the minus 10.4C Goulburn recording from July 2 disappear from the bureau’s website. “The temperature dropped to minus 10.4, stayed there for some time and then it changed to minus 10 and then it disappeared,” Mr Pidgeon said.
He relayed his concerns to scientist Jennifer Marohasy, who has queried the bureau’s treatment of historical temperature data. After questions were asked, the bureau restored the original recording of minus 10.4C to its website. A bureau spokeswoman said the low recording had been checked for “quality assurance” before being posted.
The bureau said limits were set on how low temperatures could go at some stations before a manual check was needed to confirm them. “The bureau’s quality ¬control system, designed to filter out spurious low or high values was set at minus 10 minimum for Goulburn which is why the record automatically adjusted,” a bureau spokeswoman said.
“The error was picked up yesterday internally and quality control processes are being reviewed for those stations where temperatures below minus 10 are possible.”
Dr Johnson told Mr Frydenberg the failure to record temperatures of minus 10.4C at Goulburn on July 2 was due to equipment being “not fit for purpose”.
A similar failure had deleted a reading of minus 10.4 at Thredbo Top on July 16 even though temperatures at that station had been recorded as low as minus 14.7 in the past. That temperature was still blank on the bureau’s website yesterday.
Dr Johnson said failure to record the very low temperatures had “been interpreted by a member of the community in such a way as to imply the bureau sought to manipulate the data record”.
“I categorically reject this ¬implication,” he said.
See, I told you so – they wouldn’t do that.
