The Wacky World of Weather Stations: No. 144- Kangaroo Flats (NT)

Tuesday 15/10/2019

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: Kangaroo Flats (Defence) 14982

Opened: 2017

Daily Temperature data from: 2017

Data used to adjust Acorn sites at: —

Location:   Co-ordinates -12.7934 130.8542

37km south of Darwin.

BOM site plan 2018:

Google satellite image 2019:

The screen is 5 metres from a large bank of solar panels. Talk about unrepresentative surface! As well, the site has changed considerably, with many trees removed since August 2018.

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

FAIL

Percentage of all Australian sites not compliant: 19.89%.

    Ken can you spell out the impact that a bank of solar panels has on a BOM temperature measuring device ?

    I’m sure it does have an impact but for other readers maybe just spell it out.

    And I wonder who owns this site. Clearly it’s not BOM as they would surely not ( I assume ) screw up their own site so comprehensively !
    Puzzling !

      “Generally speaking, solar panels are 20°C (36℉) warmer than the ambient temperature. For example, the ambient temperature in the desert can reach 113℉, which this means solar panels in this climate can reach 149℉.” https://www.solar-estimate.org/
      On Sunday 13 October, Tmax was 40.6. My guess is this could have been affected by the panels, but if not, the panels would have been 60 degrees Celsius plus. As well this large array of panels will affect air circulation from the east-north-east, the prevailing direction in the Dry.
      Of 14 days this month, 8 have exceeded the previous record for October (set in 2018). Every daily record temperature at Climate Data Online was set in 2018 or 2019.
      Regarding Tmin, “The researchers also discovered that solar panels prevent heat from escaping during the night when it is cooler. ” https://www.energysage.com/
      So they act like trees at night, keeping the air warmer than normal.

        Thanks for that Ken. They have a major impact ! I seem to remember that a BOM site in SA was also very close to a solar panel array. Manum from memory ?

    Ahhh ! I see it’s defence controlled site..
