The Wacky World of Weather Stations: No. 55- Moruya Heads (NSW)

Please refer back to my first post for site specifications.

Station:  Moruya Heads Pilot Station 69018

Opened: 1875

Daily Temperature data from: 1910

Data used to adjust Acorn sites at: Canberra, Gabo Island, Nowra, Point Perpendicular, Richmond NSW, Sydney.

Location: Co-ordinates   -35.9093 150.1532

About 230 km south of Sydney.

The screen is close to a timber picket fence, a concrete path, a shed and a house.  The buildings block cooling south-east winds.

Moruya Heads is part of the ACORN-SAT network used for analysing Australian climate trends.

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

    Ahhh yes ! ‘Very convenient’ for who ever is reading the BOM station equipment.

    Lots of better locations close by; but not so convenient, so not chosen by BOM despite it’s guidelines..

    Muruya is a maritime location with a temperature range much narrower than than other BOM stations in the inland areas. It’s not as hot nor as cool.

    But this station is used to adjust the data for Canberra which is well inland and also at much more above sea level …

    So they tow are in no way similar.

    Frankly using Muruya to adjust Canberra temperature record is plain scientific incompetence !

    And Muruya is an ACORN BOM weather station..It’s considered more reliable, more accurate, by BOM’s climate science geeky computer nerds. So whatever it says impacts elsewhere in BOM’s network.

    Utterly dopy BOM !

    Hi, here is a site from my home town in South eastern WA. A research station since 1932 and rural.

      Gday Macha, thanks. I’ll get onto WA.. eventually. Halfway through NSW, then Qld, NT, then WA. Salmon Gums at first appearance appears to be well sited and compliant but will have a closer look later.

        Greta. I digitised 15yrs of hand writeen daily rainfall from my family farm 1920s, entered on the official BOM cards. Will try to download max/min temps from BOM but no luck yet. I think it should be uncontaminated and show how a good site, no ocean, no UHI, etc. responds to temperature over a long time.
        Ps. CO2 should be irrelevant to choosing our nation energy mix.

    Moruya Heads’ instability is apparent in the temperature record:
    It compares unfavourably with Jervis Bay (Pt Perp) which seems to be rock solid (if you’ll forgive the pun).
