Ridge Hill tower

The Ridge Hill tower (RGL) began measuring trace gases (CO2, CH4, N2O and SF6) in March 2012. This site is located at 51.9975o N 2.5400o W, 204 m above sea level, and is 12 miles south of Hereford near the English-Welsh border. The site is registered by the World Meteorological Organisation (WMO) as a Global Atmospheric Watch (GAW) regional station. Measurements are made from two tower levels with one inlet at 45 m and the other inlet at 90 m. There are no major sources of local pollution; the surrounding area is sparsely populated and covered with arable land.

Instrument maintenance is primarily carried out by Dr Kieran Stanley but also by Dr Simon O'Doherty and Dr Dickon Young.
