There are two temperature series for Cape Bruny on the southern tip of Tasmania. CAPE BRUNY LIGHTHOUSE 94010 and it seems that an AWS was commenced in 2002 CAPE BRUNY 94198. The BoM site map shows the screen and AWS are ~18m apart. I downloaded the max and min monthly data from CDO online and … Continue reading Cape Bruny AWS reads warmer than Stevenson screen 18m away
This subject has come up in my previous post – The Conversation blog in discussing “was the 1896 heatwave wiped from the record?” – wipes BoM 1996 finding from the records – In 1997 I published a Comment on the subject of the 61 year long Adelaide temperature experiment – 1997 Hughes, W.S. Comment on, … Continue reading What reasonable conclusions could be drawn from results of the 1887-1947 Adelaide experiment comparing thermometer readings in a Glaisher stand and Stevenson screen ?
I notice over at wattsupwiththat.com Luke comments: June 13, 2010 at 4:39 am [El Gordo remarks about temperatures pre 1900 being higher but gee if we’re into UHI issues – those data were recorded in a Glaisher stand. That’s why.] Not so Luke. Luke is repeating the standard BoM excuse to avoid facing the facts … Continue reading Late 19th Century photographic evidence of the Stevenson Screen in Australian meteorology

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 … Continue reading Giles in central Australia is not a pristine weather station site
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.
Lance Pidgeon has been working on these 2002 Tables of daily temperature extremes for each Australian State & Territory from the ABS and I decided to show his findings re daily max in this Table. Minimums later. Readers can check for themselves the BoM sources we used which I have colour coded in my Table. … Continue reading BoM changing temperature extremes history
Reader Siliggy emailed this evidence of changes quietly inserted into the BoM network – that is proving “climate change and global warming”. Is there a study comparing this Beehive to stevenson screens? The picture source is page four at this NTC pdf. It is the Portland Harbour site here on the observations page for Victoria. … Continue reading BoM using “Beehive” thermometer shield in CDO
The BoM was asked to calculate the climate of the Canberra district in the process of deciding on a location for the Australian Federal Capital Territory – Chris Gillham alerted me to this report and he has his own comments on the data in a 1Mb pdf report. Looking at the temperature data in the … Continue reading 1910 Bureau of Meteorology report shows Canberra region temperatures pre-1909 were similar to the ten years 2004-2013
