Our hottest ever day 50.7 degrees at Oodnadatta tweaked hotter by BoM’s ACORN series

BoM says, our National daily max temperature record is SA, 50.7, 2 January 1960 Oodnadatta Airport 17043

Just over a year ago Onslow in WA equalled the 50.7 see my blog – “BoM equal record hot day at Onslow a nothing-burger 14Jan2022” www.warwickhughes.com/blog/?p=6850
My table comparing four versions of Oodnadatta daily max from 17Dec1959 to 17Jan1960 shows 4 columns of daily max – CDO (Climate Data Online) referred to be some as Raw, the original ACORN from 2009 which shows no changes from CDO, Acorn V2 from 2018 and ACORN V2.3 from Oct 2022. There are two columns of differences, the first is ACORN V2 minus ACORN 2009, the second is ACORN V2.3 minus ACORN V2.
I have marked with red asterisks the five days in 1959 where ACORN V2.3 is different to ACORN V2.

What a debt of gratitude we owe BoM for the $multi-millions of dollars they spend correcting for the poor eyesight of the Oodnadatta weather station custodian in 1959-1960.
