The Wacky World of Weather Stations: No. 25- Wilsons Promontory (Vic)

Please refer back to my first post for site specifications.

This is another Acorn station- supposed to be top rate.

Station:  Wilsons Promontory 85096

Opened: 1872

Daily Temperature data from: 1910

Data used to adjust Acorn sites at: Gabo Island, Orbost, Sale

Location: Co-ordinates  -39.1297 145.9865

About 200km south-east of Melbourne.

Note:  very close to concrete paths, close to stone walls, close to a house and other buildings, close to solar panels which the BOM admitted could reflect sunlight onto the screen at some times of the year, probably shaded by the house in winter, protected from cold south-west winds by the cliff face and walls and buildings- what more could be wrong?

This Acorn station is not compliant.  Temperatures are uploaded every minute and reported at Latest Weather Observations, and contribute to Acorn adjustments, but are not reliable.

    With so much area close by in that National park to choose for a weather station the BOM has this one in this place which will be impacted by everything you mention Ken.

    I suggest that the rainfall gauge will also be affected.

    Also : Does the BOM’s pdf for Wilson’s Prom show much change or development around the weather station over the long time it has been there. ?

    Or is it it unchanged from when it was established ?

    If it is not changed, we might be able to correlate changes in the site around it, with changes in the temperature & rainfall record.

    • Yonniestone Says:

      I’m thinking even if the site was unchanged and development occurred wouldn’t the basic guidelines be reassessed by BOM staff or at lest be notified by the station reader?

      Maybe people just don’t like walking too far to do the job, dunno?

    • kenskingdom Says:

      My guess is the buildings are mostly unchanged since 1872, but rock walls and concrete paths would be later. A recent change is installation of an array of solar panels a few metres from the screen.

  2. John in Oz Says:

    All of these non-compliant sites go to show that the BOM are merely using whatever is available to them, regardless of whether they meet their own guidelines or are fit for purpose.

    They must have enormous egos to think that they can take data from such bad sites, ‘correct’ it using undocumented mathematical incantations then claim the results as ‘world’s best practice’.

    One has to wonder at the gullibility/blindness/intent of our elected officials who must have seen analyses such as Ken’s but always proffer the BOM as ‘experts’.
