The BomWatch blog has published Day/Night temperature spread fails to confirm IPCC prediction examining max min and DTR temperature data from the BoM purpose built weather station Giles 13017 in far eastern WA near the WA-SA-NT border junction. The main points of the BomWatch article is that Giles is a pristine site and that DTR has not closed as the IPCC expects. In 2014 I blogged on the loony-toon BoM adjustments to Giles for ACORN 1. So I have a 2013 Giles Basic Climatological Station Metadata pdf – a sort of station diary – on my HDD. A check of the Giles pdf shows that a gravel road that ran through the instruments area near the screen was bitumen sealed in the 12 months between the Sep 2011 and Sep 2012 site maps. Ken Stewart blogged on the Giles site in 2019 The Wacky World of Weather Stations: No. 171- Giles (WA) and Ken shows Google Earth images that indicate the screen was ~20m from the sealed road. So the sealed road would introduce some quota of UHI into the data. Ken also pointed out that a 2019 site photo from JoNova shows the whole area of the screen fenced rectangle covered by gravel with no grass – Ken rates the site “non-compliant”. The 2013 Giles Basic Climatological Station Metadata pdf shows on page 23 Station Equipment History that on 1st June 1992 under Air Temperature that – “INSTALL Temperature Probe – Dry Bulb (Type Rosemount)”.
So prior to 1st June 1992 temperatures would have been recorded by liquid in glass thermometers probably in older/larger type Stevenson screen. The post 1992 probe would produce readings over very short periods of seconds which would lead to higher temperatures being recorded than would have been recorded by a liquid in glass thermometer.

Outback SA wet not so unprecedented as BoM claims
We have all seen the news over the weekend of flash flooding on the Eyre Peninsula and other areas of South Australia – this ABC article quotes the BoM saying “We’ve seen seven all-time records up until this point through the Eyre Peninsula largely,” Mr Lainio said. “Falls of anywhere between, say, 80 to 90 millimetres to over 150mm in a 24-hour period. Those locations have never seen falls of that amount.” I did a quick search for monthly rainfalls and found that an event in Feb 1946 seems in a similar ballpark to the big falls last weekend. 
Moonaree 16029 ~150km N of Kimba had over 200mm rain in Feb 1946 and 2 days around 18th registered 197mm. So here we have another instance of where the BoM aided & abetted by the ABC fail to find rain from BoM history. Map made at BoM “Recent and historical rainfall maps” – choose your time.

BoM equal record hot day at Onslow a nothing-burger
BoM claim that Onslow 50.7 yesterday matches the 50.7 at Oodnadatta in outback South Australia, on January 2, 1960.
In their “climate change dreams”. Oodnadatta was from a liquid in glass thermometer in probably an older style large Stevenson screen while Onslow would be from an AWS with a fast reacting electric platinum probe.
Maps & charts raise question the CCP released Omicron
Readers here might recall that in April 2020 I blogged “WuhanVirus as a ChiCom ops”.
On 26Jan2020 I had blogged “Australia Day & coronavirus thoughts” as it looked obvious to me people were flooding our border at airports with no health checks. Anyway – fast forward to 2Jan2022 as we cope with the huge Omicron case numbers surge and I thought “I wonder how China is coping with Omicron?”. This JHU map shows that Omicron is an absolute “nothing-burger” in China despite flooding almost every corner of planet Earth with a huge Christmas surge in Covid case numbers. So is the CCP so confident they are untouchable that they could have developed Omicron in a lab and planted it around the world? Johns Hopkins University & Medicine Coronavirus global map 
Larger map. I should have added that a week ago David Archibald has said that Omicron came from a laboratory.
