A guide to the weather station at Sidcot.
Data collection began during the first days of May 2006 The station is located in a temporary position until the summer. This may effect the readings's as follows. Temperatures may be slightly elevated from actual and wind speeds may be lower than actual when the wind speed is higher. It should also be noted that, as with all weather stations the data is for local conditions; At a distance of as little as one mile from the station, one might experience quite different weather. The accuracy of the weather forecast given is also quite limited and should be treated as such. How do you receive this web page? The weather station transmits its data
by a radio link to an indoor unit. This in turn is connected to a PC running
a program that organizes and transmits its data (including a weather forecast)
every five minutes to one of our servers. Software on the server then
uploads the information to our web site - this update occurs about every
minute for the home page graphics. and about every four minutes for other
data. Longer term data is refreshed less often, with yearly data being
updated every six hours. You may like to look at these other weather related web sites to get a better understanding of current conditions. Note: These pages will open in a new window |

Glossary:
| Air Density |
Air Density (the weight of 1 cubic foot or 1 cubic meter of
air ) |
| Barometric Pressure |
Adjusted atmospheric pressure so that it reflects what the pressure would
be if measured at sea-level. |
| Dew Point |
Dew point is the temperature to which air must be cooled for saturation
(100% relative humidity) to occur, providing there is no change in water
content. |
| Heat Index |
The Heat Index uses the temperature and the relative humidity to deter
mine how hot the air actually "feels". The lower the humidity
the lower the apparent temperature will be. |
| Solar Energy |
The amount of accumulated solar radiation energy over a period of time
is measured in Langleys |
| Solar Radiation |
Amount of solar radiation expressed in Watts per square meter (W/m2). |
| THSW |
Temperature Humidity Sun Wind Index The THWS Index uses humidity, temperature, the cooling effects of wind and the heating effects of direct solar radiation to calculate an apparent temperature. |
| THW |
Index Temperature Humidity Wind Index The THW Index uses humidity, temperature and wind to calculate an apparent temperature. |
| UV Index |
The Ultra Violet [UV] energy. |
| Wind Run |
Wind run is measurement of the "amount" of wind passing the
station during a given period of time |
