Dr Maxine Cooper the ACT (Australian Capital Territory) Commissioner for Sustainability and the Environment has a page discussing ACT weather and if you scroll down about half way you see this headline. “Has development around Canberra International Airport adversely affected its use as a climate reference station?”
Dr Cooper sees the encroaching of carparks and hangars only from 2005 but I would suggest to her that the increasing size of Canberra and associated increased urban warming over the last half century has been warping the Canberra AP data warmer for decades. Last February, air masses warmed by the SE Australian heatwaves travelled ~2500 km across the Tasman Sea to give Auckland its hottest day (32.4 on 12 Feb) since 1872. I think it is obvious that Canberra air warmed a few degrees by urban effects could at times limp its way the 10 km to the airport and affect readings there.
Anyway, the good Doctor asks the question, “How much do these developments affect the Bureau’s ability to keep using this site as a long-term reference station?”
Heavens above, if Dr Cooper is getting concerned about the Canberra AP site then the list of global sites that that Dr P. D. Jones and the Hadley Centre use to generate “global warming” trends for the IPCC should really give her cause to be alarmed.
And note, Canberra is on the Hadley Centre / Jones list.

I have heard a term, “strain at a gnat while swallowing a camel”
Anthony Watts should be pleased that some well heeled Govt. group down-under is on the job, helping him.
