The screen is at the top of a steep hill, on a sloping but clear slashed area. The screen is well exposed but a bit close to tall trees (should be at least 4 times the height, i.e. 40 metres) and on account of that I was going to leave it as “marginal”. But zooming in on the photo….

… shows dry rot taking hold. The screen is damaged and will not reflect sunlight as well. This is another example of how sites deteriorate when only inspected once a year.

That concludes the Western Australian series. WA is the worst for compliance- 63 stations out of 112 I could check are not compliant. That is 56.25%.

I will next review many stations I had originally passed over as marginal (or else I was in a hurry to pick the ‘low hanging fruit’). I will also review the number of ‘checkable’ stations which will give a final figure for percentage.

Northam weather station is located in the middle of an old bowling green roughly 40 metres across, so all else being equal it should be a good site. However, if you refer to the above images you will note that has 1.5 metre solid asbestos fibro fences on two sides, and 2.5 metre banks on the other two sides, so it is in an artificial hollow- one of the no-no’s. It is protected on all sides. (The station was moved here from another site between 1998 and 2005.)

For a number of reasons Merredin is not compliant with BOM specifications. The screen is on bare dirt, a few metres from vast areas of bitumen carpark and tennis and hard surface sports fields, 15 metres from a concrete footpath and bitumen street, with a fibro fence less than 20 metres to the south, and too close to large trees which may shade the screen in the afternoon. (The photo was taken at 2:20pm.)

But there is another feature of this station I want to highlight, as it is relevant to many other stations. Consider Jo Nova’s close up of the screen:

Note the thick mass of spider webs, indicating how little maintenance this (and all!) stations get- once a year. This may have little measurable effect on air circulation and temperature at this station, but there are very many stations close to bare soil or dirt tracks. A combination of spider webs, dew, and dust may have a much greater effect.

Another site in a rural area where the surroundings vary from bare soil to luxuriantly growing crop. The screen is 5 metres from a bare dirt driveway and 30 metres from a bitumen road. The driveway to the new house came into use between 2008 and 2013. The “open paddock” around the enclosure appears from the satellite image and the 2008 “street” view to be a wheat paddock with hay baled recently.

I first thought this station was just marginal, hardly worth worrying about. However, it is a good example of how sites change over the years, and how building development creeps up on what could otherwise be fairly well sited stations. This can be shown by looking at old site plans.

BOM site plan 1997:

There was an old screen close to the Telecom mast and shed, and a screen too close to some trees. The only other building mentioned was the Parks and Wildlife Office.

BOM site plan 1999:

By 1999 a tank had been installed, the site was still fairly open except the screen was too close to tall trees 25 metres away. Over the years site plans reveal the removal of trees and the construction of new buildings (with dates shown in the Google satellite image below:

The screen is 10 metres from the shed first identified in 2009; 12 metres from the ‘2001’ building; and less than 15 metres from the ‘2008’ building, and still very tall trees are 25 to 30 metres away.

This looks to be not a bad site, although there is a bitumen road 15 metres away. Note for later the “Native Grasses” around the screen. This was noted exactly the same on site plans in 2008 and 2013.

The station was moved from the old site beside a bitumen road in 1999:

Google satellite image 2019:

Here we can see the bitumen road, and the bare rock to the west, admittedly a few metres below the screen. Note however the dark green patches close to the screen. Here is a street view photo taken by Henry Chik in April 2017:

The dark green patches on the satellite image can be seen to be coastal scrub to about a metre high or perhaps more. Some may say the satellite image is really from before March 2018 and the scrub has been cleared since then. If so, the site has been changed. It is still 15 metres from a bitumen road and 25 metres from a much wider area of bitumen: the recommended distance is 5 times the width.

As noted above, the screen was moved from right beside a bitumen road. BOM adjusted data in April 1999 for this move. The annual effect of moving away from the bitumen road to the new more exposed site was –0.31 degrees Celsius annually. That indicates that in many other sites where the screen is too close to bitumen or dirt, non-compliance can have a very large effect on temperatures.

Update 05/11/2019: Thanks to reader Brian who has supplied current photos. The first shows vegetation around the screen more than merely “native grasses” and NOT “trimmed to a few centimetres”:

And this one shows how bad the station was up to April 1999:

Wider view:

To its credit, the Bureau has moved the station from its old position much too close to the aircraft apron to further up the runway. However there is a new taxiway under construction, probably finished by now, with large areas of bare dirt around the screen and along the construction site. At the old site, the station was non-compliant; during construction the new site is non-compliant; things will probably settle down, grass will regrow and the station will probably be compliant. But this site is a good example of how stations change. And through all the change the Bureau has kept recording and reporting temperatures as if nothing has happened.
