This site has information about, and readings from, my automatic weather station based in North Wahroonga, New South Wales, Australia, which is about 20km north of Sydney. For more information about it, see below. For the readings, click on the links. The weather station has been active since November 2014. I previously ran a weather station in Colchester, Essex, UK, prior to moving to Sydney.

The Weather Station
The weather station is a 'Fine Offset HP1000 Weather Station with WiFi'. Click here to see more details. It was installed in November 2014 in North Wahroonga, near Sydney, Australia: 33° 42' South, 151° 7' East, 178m above sea level. There is an integrated solar powered sensor suite which communicates to the base station by radio link. The base unit connects by WiFi to a router and uploads to the Weather Underground website. At the end of every month, I also analyse the data recorded using the WsWin software to produce the weather statistics pages above. The main components of the weather station are as follows:
Calculation of Sunshine Time
The weather station measures brightness but does not calculate sunshine duration. I have developed code using the algorithms known as the "Carpentras Method" and the data uploaded to Weather Underground to calculate the sunshine duration for each day. This gives a good match to the calculation the WsWin software makes. The equations and code are available for use and can be accessed if you click here.
If you have any comments, or want any information, please send me an email at firstname.lastname@example.org.
