The Wacky World of Weather Stations: No. 109- Rolleston (Qld)

Sunday 22/09/2019

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

Station: Rolleston Airport 35129

Opened: 2010

Daily Temperature data from: 2010

Data used to adjust Acorn sites at: —

Location:   Co-ordinates  -24.4617 148.6264

About 560 km north-west of Brisbane, 225 km south-west of Rockhampton.

The screen is only 43 metres from the turning area/apron.  BOM specifications for screens at airports stipulate a minimum distance of 80 metres from turning areas: the World Meteorological Organisation recommends 150 metres.  This is because starting and turning aircraft must increase throttle to overcome inertia, generating large amounts of propwash or jet exhaust.  This interferes with temperature measurement.  There are other bitumen roads and carparks and a concrete slab nearby.

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


Percentage of all Australian sites not compliant: 15.06%.

    Ken is this another FIFO airport ? The town is tiny with only 130 people.But it has that airport ! And I read that there us a coal mine 13 ks. away.

    So presumably regular flights by loaded aircraft providing lots of prop backwash & jet exhaust to the BOM screen.

    Looks like most of the “measured” global warming in Australia is Urban Heat rising?

  3. Bill in Oz Says:

    Not necessarily Viv. A lot is achieved by simply ‘mis-placement’ of BOM weather stations. Eg L putting them on a hill or raised mound where the cold air so the actual minimum temps cannot be measured. Or today’s Rolleston site which is affected by propellor air drafts or hot jet engine exhaust wind.

    They are not UHI. They are the result of BOM incompetence.
