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.
I can’t speak in relation to Odonatan, but I can in relation to Broken Hill.
The people who monitored daily max and min in BH (Post Office, Airport and ABC radio station 2NB transmitter) were excellent and as diligent as any people I have come across in a lifetime of science. They were brilliant in carrying out a mundane task with total sincerity (1945 to 1980).
Far more diligent than any of the computer jockeys and PR spooks of BoM and CSIRO in recent decades.
