My current work focuses on the measurement and interpretation of records of the key radiatively active greenhouse gases, primarily CO2, CH4, SF6 and N2O. I am in charge of two of the four DECC UK measurement sites, one in Tacolneston, Norwich and one in Ridge Hill, Hereford. Both sites make high-frequency, high-precision measurements of CO2, CH4, SF6 and N2O. In addition, the site in Tacolneston also makes measurements of a wide range of Montreal and Kyoto Protocol gases (CFCs, HFCs, HCFCs, Halons etc.) using an AGAGE instrument called the Medusa. These are unique measurement sites as air is sampled on tall towers from heights of 50 and 100 metres above ground level. Measurements therefore reflect a much larger footprint than if sampled from 10 metres above ground level. Integrating these high-frequency measurements with a Lagrangian dispersion model run at the UK Met Office to produce emission maps of UK greenhouse gases provides vital information on the emissions of these influential and radiatively active gases.
