There is an array of instruments and a web-connected logger on the roof of A block. This records:
- Wind speed, direction and gust wind speed
- Relative humidity
- Insolation (solar energy)
- Atmospheric pressure
The logger can be reached here. (NOTE: In april 2015 the URL changed and so this link may not have worked for a week or so. I corrected the link on 21 April. please let me know of any connection problems. Roger Thorpe)
It is possible to download the records directly from the logger, but these files can be very large. Each month the data is downloaded, tidied up a little and archived at:
Please read notes.txt on that page.
The data sets run from 1st March 2011
Daily, Hourly and Minute-by-minute files are available
The site and nature of the weather station were chosen to record the environmental conditions for our long-term test of photovoltaic panels. Some caution should be excersised when using the data for other purposes.
The insolation measured is that falling on a south facing plane at 30o inclination. The sensor can fall into shadow in the late afternoon.
All wind data is affected by local topology. Our site, on a roof in a built up area is no exception.
There are some holes in the data. As far as I can tell all of them are identified in 'notes.txt'
