The Wacky World of Weather Stations: No. 56- Ulladulla (NSW)

Please refer back to my first post for site specifications.

Station:  Ulladulla 69138

Opened: 1989

Daily Temperature data from: 1990

Data used to adjust Acorn sites at: —

Location: Co-ordinates   -35.3635 150.4828

Ulladulla map

About 170 km south of Sydney.

BOM site plan 2017:

Ulladulla plan2017

Note “patchy grass to 0.5m”.  In 2016 it was “dead grass”.  The two metre wide concrete path was constructed after February 2016.  Before 2002 when they were removed, the trees and shrubs extended all the way in front of the enclosure:

Note the irrigated sports field, and the darker area of the enclosure indicating it has probably been sprayed out.

The area has been sprayed out to kill the grass, compared with the green grass outside.  Also note the proximity to the metal equipment shelters.

The screen is close to trees and shrubs, a concrete path (built in 2016) and a carpark.  The grass around the screen has been sprayed out in previous years and was up to 0.5 metres in 2017.  The site changed in 2002 when dense shrubs were removed from alongside the southern edge of the enclosure.  Over the years the thick scrub and trees on the southern side of the road have grown from “1-3m” to five metres high, and 15 metres to the west of the enclosure from six metres to 10 metres.

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

  1. Bill in Oz Says:

    Lots of site which could be used by BOM to provide accurate observations.
    Instead BOM uses a site which
    1: Is sprayed with herbicide – probably by local council employees
    2: Has heat absorbing car park close by.
    3: Has a heat absorbing concrete path close by.

    Ulladulla should have a fairly stable maritime range of temperatures. But I doubt that is what is being recorded by the bOM’s equipment.

    As you say Ken, Fail !
