The screen is somewhere in the red oval, or possibly to the left hidden amongst the bushes.

This station was moved here after 2014 from an even worse site. Here it is on a slope that is overgrown with shrubs, 15 metres from a stone wall, and close to sheds, chook pens, and houses. And it is expected to report reliable representative temperatures?

This station is non-compliant, with temperatures reported at Latest Weather Observations and used to adjust data at Acorn sites.

This is one of the worst airport sites I have seen so far- up there with Gladstone and Sydney. It is surrounded by bare dirt, gravel, bitumen, buses and trucks, and a large building, at one of WA’s busiest FIFO airports. The airport has got busier over the years, and in one carpark gravel has been replaced by bitumen.

Here the satellite image is from before the screen was installed but after the AWS. The area around the instruments is a “gravel cleared area”. Not much you can do in desert areas where nothing grows but spinnifex which doesn’t take kindly to being trimmed to a few centimetres. Clearing the area will increase the amount of dust raised by winds.

This is another interesting site. If you enter the number 505053 into the data search at Climate Data Online, you will get a message saying “The station number must be between 001000 and 399999”. The BOM have not yet updated their database, and there is no metadata or site plan for this station. However it can be found by entering the co-ordinates given at Latest Weather Observations. The station is brand new. It has been set up to service the brand new Barimunya airport for FIFO iron ore mine workers. Being in a fiercely hot location, a cynic might wonder whether it conveniently might record new record temperatures for WA. The surrounding area is dry red dirt and spinnifex. Perhaps to lessen the dust (?) it looks as if blue metal has been used to surface the track around the screen.

At first glance this site looks OK. However, I have indicated with arrows above something peculiar: the 2 metre chain wire fence casts a solid shadow. Perhaps it is covered with shade cloth as was the neighbouring fence in 2013, or it is choked with weeds and long grass. This will greatly obstruct airflow.
