Please refer back to my first post for site specifications and to No. 92- Logan City for 2018 specifications. If you wish to check on this (or any) site for yourself, go to my post on how to check for yourself.

Giles is an Acorn station and about as remote as you can get. As a result it has probably the largest influence on area averaging of temperatures of any Acorn station. It has a very large influence on the official climate analysis of Australia.
The screen is surrounded by an extensive area of graded bare gravel, unlike the environment it is supposed to represent, (buffel grass, spinnifex, and low scrub). Bitumen was laid on the road between September 2011 and October 2012 and is less than 30 metres from the screen. 30 metres is exactly how far a 6 metre surface should be. The bare gravel surface right beside the screen is the main problem.
This station is non-compliant, with temperatures reported at Latest Weather Observations and used to adjust data at Acorn sites.
FAIL
Percentage of all Australian sites not compliant: 23.62%.

O.M.G.
Giles was set up by the BoM and manned for many years, but now (I understand) is automatic in operation. Supposedly one of the “best” stations.
If any station should be OK it is Giles. Surely evidence that the BoM doesn’t care what the readings are, as they think they can change them later.

Graeme Take a look at Eyre
For us South Aussies that one is even more interesting even though it’s just over the border in WA.
