The Wacky World of Weather Stations: No. 13- Viewbank (Vic)

The theme of today’s posts is NEGLECT.

Please refer back to my first post for site specifications.

Station:  Viewbank 86068

Opened: 1999

Daily Temperature data from: 1999

Data used to adjust Acorn sites at:  Laverton

Location: Co-ordinates   -37.7408 145.0972

5.0972Viewbank map

About 15km north-east of Melbourne CBD.

The station is on a ridge in open country about 80 metres from suburban houses.  A 15 metre tree is about 20 metres to the north-east, shading the screen in the mornings.

Not “trimmed to a few centimetres” but fairly similar to the surroundings.

The previous post showed the extent of neglect at Rutherglen.  The above photo shows this site also had been neglected for months and heavily overgrown with grass and weeds, and different from the surroundings.  In what condition was the screen’s interior?

This station may be spatially compliant but it deteriorates and changes with time so that after a period of neglect it is no longer compliant.  This is an Automatic Weather Station reporting continuously every minute for Latest Weather Observations.  Data changes due to site deterioration will be very gradual so will not be detected, but some effect can be expected.  It should be an embarrassment for the Bureau to have a neglected site only 15km from Head office.

Another FAIL.

    An interesting BOM weather site Ken. I know the area well from growing up close by as a teenager.

    Although this site looks rural, in fact it is now in the midst of Melbourne’s North Eastern Suburbs : Heidleberg, Lower Plenty, Bundoora, Montmorency, Eltham, Rosanna etc. And Latrobe University’s main campus is there as well. The suburbs now stretch as far as Diamond Creek & Hurstbridge. to the North East and Mill Park & Lalor to the North !.

    The only thing missing is a heavy duty industry area. And that lies not to far away to the West.( 5-10 ks )

    The rural area where this Viewbank BOM site lies is just the thin winding Plenty river valley.

    In other words this site is in the midst of a massive area of Urban Heat Island effect.

    How does BOM explain this away for Viewbank ?

    I have just looked at the BOM’s temp records from this site.
    1: The records started in December 1999. So just 19 years & 7 months of data.

    But this area was mostly suburbanised before 1999. In fact the main road nearby saw suburban development from the 1960’s with the start of Latrobe University just 5 ks away to the North.

    So I am puzzled that the BOM would establish this weather station at this site in 1999 when UHI was already a significant factor.

    2: I checked through the average monthly minimum & maximum temperature records. And for the past 19 years there has been NO significant trend towards higher or lower maximum or minimum temperatures.

    Average Minimums : http://www.bom.gov.au/jsp/ncc/cdio/weatherData/av?p_nccObsCode=38&p_display_type=dataFile&p_startYear=&p_c=&p_stn_num=086068

    Average Maximums : http://www.bom.gov.au/jsp/ncc/cdio/weatherData/av?p_nccObsCode=36&p_display_type=dataFile&p_startYear=&p_c=&p_stn_num=086068

    But simultaneously the BOM is telling us that average minimum & maximum temperatures are rising.

    Duhhhhh ?

    is this what ‘homogenisation’ does ? If so it’s just bunk.

    I was so puzzled by the Viewbank results that I went & looked at the weather recorded by the BOM weather station at Bundoora, actually Latrobe Uni. just 5 ks. away to the North up Plenty Rd.

    Consistently the average monthly maximum temperature at Bundoora is LOWER by about 0.5 degrees, than Viewbank.

    What is going on ?
