Please refer back to my first post for site specifications.
Station: Balranald RSL 49002
Opened: 1879
Daily Temperature data from: 1965
Data used to adjust Acorn sites at: Mildura.
Location: Co-ordinates -34.6398 143.5610
About 700km west-south-west of Sydney, 380km north-west of Melbourne.
The site plans go back to 1949 and reveal at least three different locations.
This site has colorbond fences surrounding the screen, buildings all around, and a tree to the northwest that has grown from 10 metres to 15 metres. The gardens in the southwest corners had weeds to one metre tall in some inspections.
This station is non-compliant, with temperatures reported at Latest Weather Observations and used to adjust data at Acorn sites.
FAIL
Percentage of all sites not compliant: 10.64%

1 : The BOM weather station is also about 7 meters from the Balranald Bowling Club with all it’s greens for members to play bowls.
The green immediately closest to the Stevenson Screen seems to be in the midst of being renovation as there is lots of bare soil showing and grass patches. Renovation is accompanied by extra watering and extra humidity.
2: You mention that the BOM weather station has been at 3 different sites. Do you know Ken if these other sites were compliant or non compliant ?
Wkipedia mentions that climate records have been kept for Balranald since 1879. Wikipedia also states : “Balranald has a semi-arid climate with hot summers, cool winters and mild rainfall throughout the year, typical of central-southern New South Wales. The winter and early spring has more rainy days than the rest of the year.”
3: When I looked at Balranald on Google Earth, there is a huge permanent planting of irrigated orchards just North of the town; maybe citrus. This is bigger than the town of Balranald itself. I assume that irrigation on this scale will have an effect on the micro-climate of the area.

2. Hard to tell, one non-compliant at least. But any move causes a discontinuity in the record so the whole record is compromised.

So maybe they should have different numbers ?
By the way Balranald on the Murrumbidgee river is part of the MIA. Irrigated crops are a major industry..
