The screen is less than 10 metres from the large circular asphalt area under a wind sock, and less than 20 metres from tarmac turning areas and taxiways.  Bankstown is a busy secondary aerodrome with hundreds of aircraft movements each day.

This station is not compliant.  Temperatures are reported at Latest Weather Observations. and used to adjust temperatures at other Acorn sites.

The screen is close to a brick wall to the south and is surrounded by buildings, a concrete footpath, bitumen roads, and a six? eight? lane freeway to and from the Harbour Bridge.  It is also shaded by a very large tree to the north.

This station is not compliant.  Temperatures are reported at Latest Weather Observations. and while the BOM acknowledges UHI and doesn’t use Sydney in climate analysis, this station is still used to adjust temperatures at other Acorn sites.

Apart from to the south, the screen is surrounded by acres of tarmac: two bitumen roads very close, an eight (?) lane freeway, taxiways, runways, and a very large parking area for large jets.

This station is not compliant.  Temperatures are reported at Latest Weather Observations. and used to adjust temperatures at Acorn sites, but while they are useful for aircrew they are unreliable indicators of temperatures for climate analysis.

The Wacky World of Weather Stations: No. 33- Orford (Tas)

Please refer back to my first post for site specifications.

Station:  Orford 92027

The station is between a bitumen road and a bitumen carpark, 20 metres from buildings, and on a sloping site- a fair bit more than a “slight fall”.

This station is not compliant.  Temperatures are reported at Latest Weather Observations. and used to adjust temperatures at Acorn sites.

The Wacky World of Weather Stations: No. 32- Dover (Tas)

August 15, 2019

Please refer back to my first post for site specifications.  Among them:  “The shelter should be freely exposed to the sun and wind, and not shielded by or close to trees….”

Station:  Dover 94020

Opened: 1901

Daily Temperature data from: 1989

Data used to adjust Acorn sites at: Butlers Gorge, Grove, Hobart.

Location: Co-ordinates   -43.3330  146.9980

About 75km south-west of Hobart.

So it was moved to the current site five years ago (between June and August 2014).  And it was moved to that location from a “Parks, Wildlife, and Heritage” site (that was also non-compliant) between 2003 and 2006.

The station is beside a driveway and in the middle of a dense stand of timber.  It would be shaded for a considerable part of each day, especially in winter.  It is not representative of the surrounding area, and there are many suitable alternative locations.  Why was it moved to this less compliant site?

This station is not compliant.  Temperatures are reported at Latest Weather Observations.  and data from the old Parks and Wildlife site used to adjust temperatures at Acorn sites- but will the next version of Acorn use the new location’s data?.

The station is on the earth and rock dam wall beside the gravel track.  The dam wall falls steeply to the north-west, and to the east to the water.  The water level rises and falls.  When high, the water has a greater moderating effect on temperatures in the screen.  When low, more bare earth and rock of the dam wall is exposed.  Thus the immediate surroundings of the screen frequently change, and it is not representative of the surrounding area.

This station is not compliant.  Temperatures are reported at Latest Weather Observations.  and used to adjust temperatures at Acorn sites.

The station is in a heavily built up area of Hobart.  It is surrounded by buildings, including the four storey BOM building to the south-west, concrete and bitumen.  Cooling winds are restricted, especially from the south-west.

This station is not compliant.  Temperatures are uploaded every minute and reported at Latest Weather Observations.   The BOM acknowledges the UHI effect at this station and so does not include it when making climate analyses- yet the BOM does use Hobart data to adjust temperatures at other Acorn stations.

The Wacky World of Weather Stations: No. 29- Launceston (Tas)

August 13, 2019

This is a crap station in more ways than one!

Please refer back to my first post for site specifications.

Station:  Launceston (Ti Tree Bend) 91237

Opened: 1980

But the bloke who did the inspection in 2015 had a better sense of humour (or was cranky at being given the job):

Yes, you can see the dung heaps.

The station is located at the Launceston sewage treatment works, on a bare bank beside a gravel road, with settling ponds to one side and very close to piles of (ahem) excrement.  Thank goodness for technology, it now reports every minute automatically so observers don’t have to go there to do readings.  What’s wrong with having a station here (apart from aesthetic reasons)? Decomposing sewage generating heat, and dark, almost black, settling ponds nearby, plus the water from thousands of hot showers, might raise the temperature a little?  And the siting is hardly representative of the surrounding area.

This station is not compliant- should I say, a real stinker?  Temperatures are uploaded every minute and reported at Latest Weather Observations, and contribute to Acorn adjustments, but are not reliable.

This site was opened in June 2013 as an improvement on the old Regional Office site on the corner of La Trobe and Victoria Streets in the inner city.  The next image shows the location move:

While it is certainly an improvement being further from the inner city, the station is too close to large areas of carpark and roads.  There are several other open spaces in parkland nearby that could have been used.

This station is not compliant.  Temperatures are uploaded every minute and reported at Latest Weather Observations, and contribute to Acorn adjustments, but are not reliable.

The Wacky World of Weather Stations: Which to include?

August 12, 2019

Readers have suggested a number of sites to look at, and some definitely have been shocking.  Site quality in Australia varies from pretty good to downright awful, and there are many in between.  How to decide stations to include in the Hall of Infamy?

There are several stations I have come across that are of fair quality, definitely not good but better than some I have seen.  These include Kyancutta 18044, Kerang 80023, Wonthaggi 86127 and Lakes Entrance 84150.  I will leave these until the end, after I have shown the worst, (and there are dozens of them)- my time and energy are limited!

So please be patient, I will keep posting two stations per day.
