Is that using ACORN1 or ACORN 2 "data".

Yes. BoM.

Now has RAW data, i.e. original data, The homogenised (adjusted) ACORN1 "data" and the new improved homogenised (adjusted) ACORN2 "data".

Before 1788.
The aboriginals were coming out of a 10,000 year 'drought' due to Ice Age.

Townsville would disagree
Where was it the driest on 32 years?

Don't worry about lee, his sole purpose is to try and confuse, obfuscate and discredit.

So the post heading says it is the hottest summer record. The claim then is it is the driest in  32 years.

The good news for the second event must be that it was as dry or drier 33 years ago. Damn. That global warming precipitation just keeps on varying.

And I am asking you whether it is the RAW data, ACORN1 "data" or ACORN2 "data" that they are using?

Seeing it was the "hottest summer on record" they must use the climate "data".

"The Australian Climate Observations Reference Network – Surface Air Temperature (ACORN-SAT) dataset has been developed to monitor climate variability and change in Australia."

http://www.bom.gov.au/climate/change/acorn-sat/

So is it ACORN1 "data" or the new improved ACORN2 "data"?

"The Bureau's updated dataset is known as ACORN-SAT version 2, or simply, ACORN-SAT.

It is standard practice for major meteorological organisations to update their datasets, to ensure they are incorporating the latest scientific understanding, computing capabilities and additional data.

The aim of such revisions is to provide improved estimates of historical changes in climate. ACORN-SAT version 2 reaffirms the results of previous datasets which chronicle Australia's warming trend."

So just adjust the adjustment of ACORN1.. That way we get a new improved estimate.

BTW - ACORN uses data from 112 stations Australia wide. So 7.6 million sq km's divide by 112. An average of only about 67,800 sq km each. Although because there are more stations in the south east that would skew the result. Just imagine if they were all in the northern half of Australia.

And I thought adjusting for UHI was to lower the temperatures.

Poor lost fishy. Still stuck in his caravan to nowhere.

But it is good to see that you have no rebuttal.

Oh dear poor petal can't work it out so it must be my fault.
