The FifeWeather station is based on
Oregon Scientific
WMR928NX weather station hardware and was first installed in February 2006,
with data records commencing on the 17th of the same month.
The station hardware
consists of four
separate wireless sensors
which transmit data back to a control console. The console
communicates the data received from the sensors, to an adjacent
computer (running "Weather Display"
software) dedicated to the task of recording the data and updating
the web pages on the web server.
With the exception
of hardware and/or software failures, the
weather station runs 24x7x365.
The four meteorological sensors that make up the station consist
of a "tipping-bucket" rain gauge with ~0.35mm bucket resolution, an
external thermometer/hygrometer (for temperature &
relative humidity) housed in a small passive radiation shield,
a combined anemometer/wind vane for measuring wind speed/direction
(installed approximately 9 meters above ground level),
and an internal barometer/thermometer/hygrometer which is primarily
used to report on air pressure (but also reports on
indoor temperature and relative humidity).
The three external sensors are each attached to their own transmitter
module containing a small solar panel for power. These
transmitter modules also contain a small rechargeable cell to provide
power in the absence of sunshine, along with 2 AA cells for backup
purposes.
Data is transmitted from the sensors approximately once every 45
seconds, with the exception of the anemometer/wind vane which transmits
back to the console every 14 seconds.
The location of each of the sensors has been selected to provide the
best possible readings within the constraints of the installation
environment.
The station itself is located at 423 feet above sea-level on the
Northern side of Lochgelly
in the Kingdom of Fife, Scotland. The station is positioned close to the North Western
outer edge of a built up area, with fields and farmland beyond the urban area to the North and
West. A golf course is located to the South West and further built up areas to the
South, East and North East. Loch Ore, a large body of water, is located
approximately 2.5 to 3 miles away, to the North North West.
The adjacent aerial photograph illustrates the geography directly surrounding the FifeWeather station.
The edge of the golf course is visible in the bottom left hand quadrant of the photograph,
with the expansive farm land visable to the North and North West of the built up area. (Image
