The Wacky World of Weather Stations: No. 233- Loxton (SA)

Monday 18/11/2019

Please refer back to my first post for site specifications and to No. 92- Logan City for 2018 specifications.  If you wish to check on this (or any) site for yourself, go to my post on how to check for yourself.

Station: Loxton Research Centre 24024

Opened: 1984

Daily Temperature data from: 1984

Data used to adjust Acorn sites at: Mildura.

Location:   Co-ordinates  -34.4390 140.5978

190km north-east of Adelaide.

BOM site plan 2019:

Google satellite image 2019:

The screen is a few metres from a dirt track and surrounded by ploughed bare ground. There are irrigation sprinklers nearby- the whole district is irrigated. The surrounding vegetation is subject to change by human intervention.

This station is non-compliant, with temperatures reported at Latest Weather Observations and used to adjust data at Acorn sites.

FAIL

Percentage of all Australian sites not compliant: 32.18%.

    Ken it’s actually worse than you say.

    Loxton is a dessert climate area with a very low rainfall. All crops are irrigated.

    Loxton research Center is SA’s main citrus, avocado, stone fruits, dates, and almonds etc. research center. There is also some grape varieties research there. They used to do some annual crops like garlic but that has been closed down for the past 10-15 years.

    So the plantings are permanent tree plantings which are all irrigated. The irrigation affect moisture levels in the air and that affects the temperatures measured by the BOM’s instruments.

    But when the research on a particular variety of fruit is finished ( and hopefully commercialised ) the trees are bulldozed to make room for the next project.

    I know this from the experience as a member of the SA Rare Fruits Society. In the early 2000’s a block of rare heritage apricot & fig varieties was bulldozed. We ‘rare fruities’ were given a week or so to get up to Loxton and take budwood from the bulldozed blocks.

    And when a block is bulldozed it might lie empty for a year or two before a new type of fruit tree is planted in the block. And of course it is NOT irrigated during this time.

    That is what the Google earth image shows. The blocks around the BOM station have been bulldozed. And lie empty waiting for a new fruit research project to begin in them.

    And so there is an enormous variation in the background conditions. And an enormous variation in what that BOM station is measuring.

      The block containing the AWS is being used for barley trials. Try visiting the centre instead of relying on satellite images.

        A bit hard to visit, there’s covid19 about. Barley, fruit, or whatever crop, the surrounding land varies between bare soil and growing crop, so the station is not compliant.
