I've linked to exactly that. And the audit and independent review processes that check and report on that.
But dumbass conspiracy theorists still blather on. It's a conspiracy isn't it, jopo. Resistance thermometer producers are in on it. BoM staff that check calibration are in on it. The World Meteorological Organisation that recognises these processes is in on it. Independent reviewers are in on it. And the Abbott government that didn't investigate this conspiracy must have been in on it as well.
You and your denial mates are looney tunes conspiracy theorists.
