Heat-wise – September was a pussy in Australia

Charts here of max t anomaly show you several previous Septembers were hotter than 2017 – starting with 1928.
The UAH satellites Australia band has eleven hotter Septembers.

You can make BoM max min and mean t anomaly maps – have fun.
Going back to the charts if you make a mean t anomaly chart for Australia – which gives you a relative idea of what goes through to IPCC globull-warming central – the Oz contribution heat wise last month was even more insignificant with many previous Septembers warmer than 2017. There – some perspective.

Listing worst BoM errors in Goulburn Airport or Taralga daily minimums

Data from CDO disk bought from BoM in 2007 plus from CDO online then compared to Minimum temperature daily contour maps. Ask me if you can not find daily t in CDO or the maps.

Error A 5 Jan 1991 Goulburn Airport min = 9.7 – Taralga min = 19.2 – diff = -9.5 There is no sign of the 9-12 contour colour near Goulburn so the BoM map is indicating Goulburn is in error. Proved by Goulburn Tafe @ 20.5.

Elementary BoM temperature data errors go international

You have to pinch yourself – during 1990 the Goulburn Airport AWS 70330 daily minimums record way to many “zero’s” particularly in November & December. Such an elementary string of errors that should have been edited out. But we see the great USA climate group NOAA through their GHCN data imported Goulburn Airport AWS errors which can all be seen in the station data downloadable from the KNMI Climate Explorer – select first column GHCN-D V2 “minimum temperature” – enter Goulburn – click “Get stations” button – select Goulburn Airport AWS click “get data” link- then above top graphic click “raw data” link. A month ago we blogged on the issue of other errors at Goulburn Airport AWS. Persistent truth telling climate sceptics cause the BoM to shaft itself again. Here is a screen shot of the KNMI Goulburn Airport AWS minimums page header.

178 years of Adelaide rainfall

A reader mentioned to me that Sir George Kingston had kept rainfall data at Grote Street Adelaide from 1839-1878 and that data was in the South Australian library. The BoM has added the first 22 years of the Kingston data to West Terrace making West Terrace start in 1839 – I have added Kent Town post ~1978. This chart as per BoM – The Grote Street data is v slightly different 1839-1860 – then a bit more different 1861-1878 – I can add that later. I am sure there will be points to comment on – but I found it interesting that 1974 is not noteworthy despite Lake Eyre filling. Large graph.

Persistent truth telling climate sceptics cause the BoM to shaft itself again

We blogged on this subject 6th July – But sceptics have been busy behind the scenes as evidenced by Jennifer Marohasy who has blogged a deliciously misleading letter of explanation from the BoM to Minister Frydenberg. Oh how quick the BoM colossus can respond when the Minister’s office calls.
Today Jennifer and Lance have made the front page of The Australian. For large picture. I can hear the BoM molars grinding from here.

I think this is the text of the article – came in by email Continue reading Persistent truth telling climate sceptics cause the BoM to shaft itself again
