Interestingly the ACORN-SAT data set was touted as the most accurate temperature set of all time.
Following investigation of the methods and accuracy an audit was ordered by the government. Shortly before the audit was to take place the BOM released another version, ACORN2 which conveniently negated the audit for ACORN-SAT and was claimed to be even more accurate.
Following the release of ACORN2 numerous errors were found including over 1,000 minimum temperatures that were higher than the maximum.
Great example of the kind of bastardry that goes on at the BOM.
ACORN2 also had Albany as the highest temperature ever recorded in Australia at 51.2C.
Ever been to Albany? Coastal town on the Southern Ocean.
ACORN2 lasted about 18 months before it was replaced with ACORN3.
Strangely after all the hysterical laughter that followed the Albany temperature it was downgraded to 49.3C (raw temperature 44.5C)
Another strange thing about all three data sets was that the older temperatures got progressively colder thus increasing the warming trend.
Lairs, shonks, con men and totally corrupt organisation and so called scientists with no morals.
