In May 2014 I got a reply from Dr Rob Vertessy, Director of the BoM – to my pointing out that the ACORN-SAT data set had about a thousand examples where a daily MAX was less than the daily MIN. Dr Vertessy said that he expected that these errors would be corrected in an updated version of ACORN-SAT in the second half of 2014.
I just checked ACORN data for Alice Springs back to 1986 and the exact errors discovered by Ed Thurstan in 2013 are still there.
I have not got time to check for a thousand errors so I am assuming the ACORN update is running late. I am not surprised – as I point out in my articles examining ACORN data for Cobar – the ACORN methodology is illogical – relying on computer driven data mining comparisons hundreds of km from Cobar while ignoring data much more adjacent. Cobar ACORN I and Cobar ACORN II. The BoM should save taxpayers some money and scrap the ACORN disaster now.
In both logic and science, if your adjustments to raw data induce errors into the final result, you should revert to the raw, measured data until you are sure that the adjustments are accurate.

The ABC & Public Service Sector Superannaution is probably too heavily invested in AGW for them to tell the truth, report the real figures or make science/logic based conclusions.
While the BoM are at it, it could sort Bourke’s record out from Feb 1999-Aug 2002.
Here’s an extract. Notice something interesting?

Same numbers as in CDO – I see the no decimals format started when the Airport data commenced Dec 1998 and carried on till late August 2002. It sure does lend to a few strings of days with exact same t.

Well, the do die, but they never become extinct.
Ato- Steffen who appears in the Climategate emails. His understanding is zero unless he is telling lies. Let you decide but for me he is a joke.
