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.

Carnegie in central WA is used in ACORN to adjust Giles!!! Replaced original WA map with Australian map and added 3 days of August.
So obvious that a rain instrument has gone troppo.
Did not like the switch to Spring.
BOM: Australia’s hottest winter on record, maximum temperatures up nearly 2C on the long-term average. I am too busy to do more on this heap of exaggerations but will do so next week. In meantime readers please have a go.
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.

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.
So sweet to see the BoM getting publicity – buy the paper. Try googling – Wrong end of the stick on temperatures. Or try this Fresh doubts over BoM records after thermometer read at wrong end For large image.
No doubt a headline event for the WA Watercorporation. There seems to be errors in the BoM map for example the 100% line should go west from Perth to the coast on basis Swanbourne and Rottnest – see data at AWN map. The brown area NNE of Wagin seems to lack data justification too in stations I can see at the CDO map. For large map.
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
I had Lance staying overnight and this subject came up – me opining after watching too much ABC TV news for years – that some site must have hit the 50° in the last several years. When Lance pointed out on BoM pages that the last 50° plus was in 1998 – I felt somewhat conned. We searched Google and sure enough we found this article “The proof Australia is getting hotter” – which includes this rather specific claim – Quote “While Western Australia had a cooler than average year in 2016, some parts of the giant state did hit 50 degrees, Australia’s observation of such heat a first in two decades.” Well if 50 was hit it was not noticed in official BoM daily data. Screen saved. What an amazing lie – “fake news” indeed. Part of my conning was BoM news early in 2013 of the extension of temperature scales up into the 50’s. Oddly this neat animated map from Feb 2016 does not extend to cool temperatures around -10 that are quite common this winter. What other plus 50’s (122F) are there that the BoM should recognize?
