"Raw and adjusted data – fully available, mostly free"
Articles have been posted on this forum re the battles that people have had with the BOM trying to get raw data from them, trying to get data from weather stations where the mercury thermometers were the new electric sensors were used in parallel. First, they said that the data didn't exist, then it would take too much time, then they wanted $10,000 to supply it, they were eventually forced under a FOI request to give some data but then only a tiny bit.
They have revised the ACORNSAT data several time as they have retrospectively cooled historical temperatures, the last revision resulted in a 23% increase in the rate of warming.
