three years of inconvenient questions and the backing of more and more politicians and reporters finally forced the BOM to call in some semi-independent statisticians to form a technical forum on BOM data and methodologies. it convened for a whole day back in March, and the report is now out. http://www.bom.gov.au/climate/change/acorn-sat/documents/2015_TAF_report.pdf
while it is the usual whitewash that we are so accustomed to seeing in climate science Inquiries, it seems to actually leak out some confirmation of the problems documented by 'unsolicited submissions from members of the public', 'which fall outside the scope of the Terms of Reference'.
specifically it admits that there is no way to replicate the BOM dataset because of the 'choices within the adjustment process remain a matter of expert judgment'. hmmm. when people ask questions the BOM, (GISS,BEST, etc) say read our methodologies. but that doesnt cover the discretionary decisions being made outside of the general method. or the order of adjustments for that matter. matrix math shows the large differences a slight reordering makes, wholesaler multiple discounts also show how multiple steps produce different outcomes.
anyway, here are a coupla links from down under.
If it can t be replicated it isn t science BOM admits temperature adjustments are secret JoNova
