The Wacky World of Weather Stations: No. 100- Tin Can Bay (Qld)

Wednesday 18/09/2019

This post represents a small milestone- the 100th station identified as being non-compliant with Bureau of Meteorology specifications.  Of the 430 sites I have looked at so far, this means over 23% do not comply in some way.

Please refer back to my first post for site specifications and to No. 92- Logan City for 2018 specifications.

Station: Tin Can Bay (Defence) 140010

Opened: 2018

Daily Temperature data from: 2018

Data used to adjust Acorn sites at: –

Location:   Co-ordinates   -25.9351 152.9647

TinCanBay map

About 170km north of Brisbane.

2019 BOM site plan:

TinCanBay plan2019

Though this site was supposed to be opened in 2018, there is a 2016 site plan showing it in exactly the same location.

2019 Google satellite image:

The screen is well away from the trees and bitumen road on the old disused airstrip, but “mostly grassed” means mostly bare soil, compared with the much darker grass between the trees 50 metres north-west.  The site is not at all representative of the surrounding vegetation.  While the grass is likely to regrow and thicken in time, this means that the site’s micro-climate will change with it.

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 sites not compliant: 13.81%- but hang around, there are many more stations to check, and I can promise the non-compliance rate will get much, much higher.

    This is defence Department land Ken ? Are you sure in old airstrip no longer being used. The clearing there looks fairly fresh with lots of bare earth from dozing work.
    I am perplexed why BOM would consider establishing a new weather station there in 2018 if it was a disused airstrip.
    But you are completely right. It is not compliant with the BOM’s own guidelines for such weather stations. The bare earth all around will generate warmer temperatures on the thermometer than otherwise.
