Please refer back to my first post for site specifications.
Station: Meningie 24518
Opened: 1864
Daily Temperature data from: 1966
Data used to adjust Acorn sites at: Cape Borda, Robe, Mount Gambier
Location: Co-ordinates -35.6902 139.3375
About 130km south-east of Adelaide.
The screen is the white dot in the red ellipse.
The screen is in the backyard of the Post Office. It is about 6-7 metres from a large concrete carpark to the east and less than 10 metres from concrete to the west, about 3 metres from a skip, close to sheds, with other buildings around and a very large tree to the south.
This site is not compliant, so temperatures recorded here are not reliable. Meningie’s temperatures are published at the BOM Latest Weather Observations page, and also used by the BOM in weather reports, potentially including extremes of heat or cold. As well, Meningie is one of the sites used to adjust temperatures at ACORN-SAT sites at Cape Borda, Robe, and Mount Gambier. Acorn sites are used for climate analysis- whether winters are getting warmer and summers hotter for example. So the lack of quality at any site DOES MATTER!
Another FAIL.

How close is the road? 12m? Assume it is black bitumen.

About 10 metres, and yes blue-grey stones on bitumen.

Yes both roads are bitumen sealed roads.
It’s curious this is possibly the most compliant of the five you have posted about Ken.
NOT compliant ( = fail ) but more complaint than the others maybe ?

There is a variety as you’ll see in coming posts. Some more compliant than others, some less compliant at certain times of the year.

Hot bitumen near any site will lead to heated air blowing past the gauge at some degrees higher than would be the case for grass or even soil. The black bitumen may also cool faster at night so it may be instructive to just see if the diurnal temperature range is affected and perhaps larger than usual.

John the bitumen roads absorb more radiant heat during the day. And at night that extra heat is re-radiated out into the air. This process means that the air around sealed roads stays warmer at night than otherwise.
And thus the minimum & maximum temperatures recorded are higher than otherwise.
But increasing the minimum & maximum temperatures is precisely what ‘Global Warming” supposedly does..
Ummmm ?
