The Wacky World of Weather Stations: No. 6- Eudunda (SA)

Please refer back to my first post for site specifications.

Station:  Eudunda 24511

Opened: 1880

Daily Temperature data from: 1965

Data used to adjust Acorn sites at:  Cape Borda, Nuriootpa, Snowtown

Location:    Co-ordinates  -34.1754 139.0847

Eudunda 24511 map

About 110km north-east of Adelaide.

2010 Street view (from the west):

Eudunda 24511 street

The screen is in the backyard of the Post Office.  It is on a slope with a 1.5 metre galvanized iron fence on three sides (10 metres away on two sides) and bushes and trees nearby.  On the southern side of the fence is a concrete driveway and carpark.

This site is not compliant, so temperatures recorded here are not reliable.  Eudunda’s temperatures are published at the BOM Latest Weather Observations page, and also used by the BOM in weather reports, potentially including extremes of heat or cold. As well, Eudunda is one of the sites used to adjust temperatures at ACORN-SAT sites at Cape Borda, Nuriootpa, and Snowtown. Acorn sites are used for climate analysis- whether winters are getting warmer and summers hotter for example.  So the lack of quality at any site DOES MATTER!

Another FAIL.

    Thanks Ken ! You are powering along ! Great work.
    But I have a suggestion : could you post an example BOM weather station which is complaint with BOM’s own guidelines ?

    Then anyone reading here would al know what a compliant one looks like.

    OK, can do!

    Ken what are those two huge white buildings in the background here at Eudunda. They look like grain silos but I am not sure.

    But they are both big white ferro cement concrete structures that absorb sunlight during the day by the bucket load, And then release that heat at night…
    Surely another reason why this BOM site is a bomb site as weather station !

    Thanks Ken et al,
    Too crook to do this myself (but now positively in recovery), but it would be fascinating to compare two like, adjacent areas, one with watered lawn and one with no watering.
    The point I am making is that we all have our pet culprits for noise-making activities. But, there is scarce quantitative info. How neat would it be to comment on a site with words like “Has watered lawn bias that can make a difference of up to 2 deg C. Reference xxxx”. Or even to note that “The largest type of error for this type of site is lawn watering.”
    At present, it is like UHI, with many imagined causes of error but few measurements, let alone estimates, of strength of error.
    More items on the wish list! Geoff S

      Geoff, how does a watered lawn make a difference ? Please explain.
      I discovered 3 weeks ago that the Mount Barker BOM site is just 150 meters away. It is in the middle of a front garden lawn. It is not being watered now in Winter because it’s been raining here. But I suspect it was last Summer & Autumn.
