Australian scientist calls for ‘heads to roll’ over adjusted temperature data (WUWT)

 

Anthony Watts / 2 days ago August 26, 2014

Yesterday we posted on BoM’s bomb on station temperature trend fiddling. where BoM claimed the trend difference was a result of a station move. Apparently, BoM can’t even keep track of their own station histories! Today, Dr. Jennifer Marohasy writes: Who’s going to be sacked for making-up global warming at Rutherglen?

She writes: HEADS need to start rolling at the Australian Bureau of Meteorology. The senior management have tried to cover-up serious tampering that has occurred with the temperatures at an experimental farm near Rutherglen in Victoria. Retired scientist Dr Bill Johnston used to run experiments there. He, and many others, can vouch for the fact that the weather station at Rutherglen, providing data to the Bureau of Meteorology since November 1912, has never been moved. Senior management at the Bureau are claiming the weather station could have been moved in 1966 and/or 1974 and that this could be a justification for artificially dropping the temperatures by 1.8 degree Celsius back in 1913.

The temperature record at Rutherglen has been corrupted by managers at the Australian Bureau of Meteorology.

Surely its time for heads to roll!


The unhomogenized/raw mean annual minimum temperature trend for Rutherglen for the 100-year period from January 1913 through to December 2013 shows a slight cooling trend of 0.35 degree C per 100 years. After homogenization there is a warming trend of 1.73 degree C per 100 years. This warming trend is essentially achieved by progressively dropping down the temperatures from 1973 back through to 1913. For the year of 1913 the difference between the raw temperature and the ACORN-SAT temperature is a massive 1.8 degree C.

In the case of Rutherglen the Bureau has just let the algorithms keep jumping down the temperatures from 1973. To repeat the biggest change between the raw and the new values is in 1913 when the temperature has been jumped down a massive 1.8 degree C.In doing this homogenization a warming trend is created when none previously existed.

The Bureau has tried to justify all of this to Graham Lloyd at The Australian newspaper by stating that there must have been a site move, its flagging the years 1966 and 1974. But the biggest adjustment was made in 1913! In fact as Bill Johnston explains in today’s newspaper, the site never has moved.

Surely someone should be sacked for this blatant corruption of what was a perfectly good temperature record.
