EMEP Supersite at Auchencorth Moss

The UNECE Convention on Long Range Transboundary Air Pollutants operates a number of measurement and monitoring programmes, including EMEP – the Co-operative Programme for Monitoring and Evaluation of the Long-range Transmission of Air Pollutants in Europe. The United Kingdom contribution to the EMEP monitoring strategy is based on the creation of two Level II 'supersites', one in the north of the UK and one in the south. The site at Auchencorth Moss is the northern supersite. Additional measurements are made to qualify the site as an EMEP Level III site. Data at hourly or daily frequency are supplemented by long-term integrating measurements from existing Defra-funded monitoring networks across the UK. The site has been used by the Centre for Ecology & Hydrology for several years as an intensive monitoring site for trace gas and particle concentrations and fluxes. The site is based in an area of upland deep peat, with heather and grass cover, and has an extensive fetch to the south-west.
