Welcome to Fermilab's weather data site (provided by the Environmental Protection Group of the ESH&Q Section). Fermilab's meteorological (met) station became operational in 1992. Located in open field, the station is solar powered and consists of a 30-foot tower (as of September 2002) to which the following instruments are attached: temperature and relative humidity sensor, tipping-bucket rain gauge, combined wind speed and direction sensor, barometer, and pyranometer. The station's geographical location is North 41° 51' 22.5", West 88° 14' 19.0" at an elevation of 740.7 feet above Mean Sea Level (MSL). See an aerial photo of its location on site.
