The Wacky World of Weather Stations: No. 52- Guyra (NSW)

Please refer back to my first post for site specifications.

Station:  Guyra 56229

Opened: 1981

Daily Temperature data from: 1981

Data used to adjust Acorn sites at: Inverell, Port Macquarie.

Location: Co-ordinates   -30.2122 151.6794

Guyra map

About 450km north of Sydney on the New England Tableland.

2019 Google satellite image:

BOM site plan 2018:

Guyra plan2018

This site plan shows the screen is about 10 metres from the hospital building and 15 to 20 metres from asphalt and concrete areas- but what is the dark oval in the satellite image?  Site plans for 2013, 2014, and 2015 tell us:

Guyra plan131415

Piles of wood chips for garden mulch have been stored there over the years, and have been very close to the screen.

Further, the site has moved at least three times, as the 2012 plan shows:

Guyra plan2012

The screen has been and probably still is close to mounds of wood chips at varying heights and distances, possibly a heat source on cold nights as the wood chips decompose.  As well, it has moved at least three times so exposure has changed.

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

    How long is this project going to take you Ken?

  2. Bill in Oz Says:

    Ken, more power to your arm mate ! This ‘project’ is really worth doing.
    And maybe, at the end, send a fee & expenses account to BOM from a very needed outside consultant !

  3. Bill in Oz Says:

    And now for this Guyra BOM weather station : I am perplexed about the huge pile of wood chips. Is it the same pile of wood chips sitting there all those years ? Or is it being added to by new wood chips with old stuff being removed ?

    If t is a single static pile, then the composting process would have ceased after about 6 months. But if new chips are being added then the composting process ( and thus extra heat ) would continue.

    Though this would also depend on whether water was available from rain or a hose. Guyra is currently in drought so no rain and not much water for a hose.

    A thought : BOM weather stations seem to be located just where it is ‘convenient’ NOT where the guidelines permit.

    Ummmm ?.
