Longterm Carbon Monoxide and Molecular Hydrogen measurements at the Weybourne Atmospheric Observatory (WAO) using a Reduction Gas Analyser operated by the NCAS (National Centre for Atmospheric Science) AMF (Atmospheric Measurement Facility). WAO, situated on the north Norfolk coast, is part of the School of Environmental Sciences at the University of East Anglia (UEA) and is a world class facility for fundemental research, background atmospheric monitoring and teaching purposes. WAO operates a range of instruments in its measurement programme - the data from which is archived at the BADC. The atmospheric carbon monoxide and molecular hydrogen are measured every 6 minutes.
