All Australian weather station sites have moved and changed in ways that impact data. Consequently, trends in raw data are as fraught as poorly adjusted data. Thus, the overarching question for any long-term temperature record is whether methods used to adjust for non-climate impacts are appropriate and unbiased. Appropriate requires that adjustments directly align with significant changepoints in data, while unbiased requires they are directly proportional to the effect.
