Daily Temperature data from: 1859

Data used to adjust Acorn sites at: Bathurst (1956), Moruya Heads (1966), Nowra (1972), Point Perpendicular (1976), Richmond NSW (1994).

Location: Co-ordinates   -33.8607 151.2050

The screen is close to a brick wall to the south and is surrounded by buildings, a concrete footpath, bitumen roads, and a six? eight? lane freeway to and from the Harbour Bridge.  It is also shaded by a very large tree to the north.

This station is not compliant.  Temperatures are reported at Latest Weather Observations. and while the BOM acknowledges UHI and doesn’t use Sydney in climate analysis, this station is still used to adjust temperatures at other Acorn sites.

    Well why not have BOM weather station right there in the middle of Sydney CBD ? After all Sydney folk have a right to know how HOT their CBD is !

    But why is the data from this site used to ‘adjust’ the data from other better located weather stations ?

    It’s far to much influenced by UHI effect to provide any valid data about elsewhere.

    Bill, it is also far to much influenced by the pasing traffic to provide any valid data about inner Sydney. It has been known as worthless by anybody who looks at its position, or has seen temperature readings from Ft. Denison nearby.
    But it can be ‘relied’ on to provide high temperatures “confirming” Global warming.
    I must say though that this series has been eye opening. I’ve recommended it to 3 people to get a check on the BoM.
