Tucked in behind a hedge ( 3 to 4 metres) and a 1.8m paling fence, and close to sheds and buildings, what hope does this station have of reporting reliable temperatures?

Remember Streaky Bay?  Here’s another station caught in the act of moving.

But the screen doesn’t appear in that photo- where is it?

Sometime before May 2019 (but after July 2018) the station was moved to a more open site.  Here’s the old site plan:

Barraba street 2

Oh dear, what a poor, neglected weather station, littered with old cable reels and other unwanted rubbish, close to buildings and a laneway, surrounded by long grass, beside a wooden paling fence and near a gravel driveway. At last the Bureau has got around to moving it.

This station was not compliant, but temperatures were reported at Latest Weather Observations and used to adjust data at Acorn sites.  It is in a better position now, but still beside a dirt road.

From BOM’s specifications:  “The site should not be in a hollow or on a steep slope. “

While the station is on a level bit of ground about 16 metres wide, the site sits on a steep slope- so steep that the steps are steep.

Looks perfect?  Looks can be deceiving.

BOM site plan 2014:

BombalaAWS plan

Far from having vegetation trimmed to a few centimetres, the screen is surrounded by grass up to half a metre high.  The tipping bucket rain gauge and screen are often both mounted on a metal arm.  Cattle rubbing on the arm and/or screen will cause vibration at the least, not to mention heat from bovine body temperature and possible fresh manure and urine.

So we have a problem.  There are many stations not in an enclosure, and in many of them livestock graze nearby.  This is the first I have seen where the annual inspection reveals cattle rubbing on the apparatus.  That was in 2014.  I wonder if anything has been done about it?  As they have evidently recognised the Buffalo Fly problem, and a fence is out of the question, perhaps the Bureau has added an insecticidal back rubber to the bar?  Or recommended introduction of Brahman bloodlines?

Shh!  The Bureau would not want word getting out, people might laugh at them.

This station is not compliant, with temperatures reported at Latest Weather Observations but not used to adjust data at Acorn sites.

The screen is very close to bitumen on three sides, close to a wide (four track) railway corridor and a four lane highway to the east, on a slope, with trees nearby.

And it was moved here from a supposedly poorer site between September 2006 and November 2007:

The screen is centred in a bare back yard, but is surrounded by large brick buildings and a 2 metre wooden paling fence.  It is not possible to tell from the satellite image whether the yard is lawn or bitumen, but it doesn’t look green.

The Wacky World of Weather Stations: No. 56- Ulladulla (NSW)

August 27, 2019

Please refer back to my first post for site specifications.

Station:  Ulladulla 69138

Opened: 1989

Ulladulla map

About 170 km south of Sydney.

BOM site plan 2017:

Ulladulla plan2017

Note “patchy grass to 0.5m”.  In 2016 it was “dead grass”.  The two metre wide concrete path was constructed after February 2016.  Before 2002 when they were removed, the trees and shrubs extended all the way in front of the enclosure:

BOM site plan 2000:

Ulladulla plan2000

Ulladulla aerial

Note the irrigated sports field, and the darker area of the enclosure indicating it has probably been sprayed out.

2010 Google street view:

Ulladulla street

Street view close up:

Ulladulla streetcloseup

The area has been sprayed out to kill the grass, compared with the green grass outside.  Also note the proximity to the metal equipment shelters.

The screen is close to trees and shrubs, a concrete path (built in 2016) and a carpark.  The grass around the screen has been sprayed out in previous years and was up to 0.5 metres in 2017.  The site changed in 2002 when dense shrubs were removed from alongside the southern edge of the enclosure.  Over the years the thick scrub and trees on the southern side of the road have grown from “1-3m” to five metres high, and 15 metres to the west of the enclosure from six metres to 10 metres.

This station is not compliant, with temperatures reported at Latest Weather Observations but not used to adjust data at Acorn sites.
