UKEAP is coordinated by UKCEH with sites distributed across different rural land use and habitat types throughout the UK. Sites are equipped to automatically sample and measure atmospheric chemistry at high- and low-frequency, and supported by intensive measurement campaigns. UKEAP integrates four component monitoring networks that measure airborne acidifying and eutrophying chemicals:
• National Ammonia Monitoring Network (NAMN: 85 sites): monthly ammonia concentrations.
• Acid Gas and Aerosol Network (AGA-Net: 30 sites): monthly gas phase SO2, HNO3, HCl; major particulate phase inorganic anions and cations.
• Precipitation Network (Precip-Net: 39 sites): fortnightly inorganic anion and cation concentrations in precipitation.
• NO2Net (24 sites): four-weekly triplicate NO2 concentrations.
UKEAP also operates two EMEP network 'supersites' in the UK (EMEP = European Monitoring and Evaluation Programme for long-range transmission of air pollutants): Auchencorth Moss Atmospheric Observatory (Scotland, upland peat moor - listed elsewhere in this catalogue) and Chilbolton Observatory (Hampshire, lowland arable site).
UKEAP components were established as follows: Precip-Net 1985 (led by Ricardo); NO2Net 1994 (led by Ricardo); National Ammonia Monitoring Network 1996 (led by UKCEH); AGA-Net 1999 (led by UKCEH); Auchencorth Moss 2006.
UKEAP is the only pan-UK monitoring network for eutrophying and acidifying pollutants. UKEAP networks are unique in terms of their temporal and spatial coverage.
Data from the UKEAP sites are available on the Defra UK Air portal:
Researchers wishing to access UKEAP facilities should contact the network manager, Christine Braban at UKCEH Edinburgh.
UKEAP operates air quality monitoring networks across the UK: NAMN (85 sites); AGA-NET (30 sites); Precip-Net (39 sites) and NO2Net (24 sites).
UKEAP is funded by Defra and NERC National Capability LTSS: UK-SCaPE programme.
Outputs from UKEAP air quality monitoring are used by Government policy and regulation teams; air quality and climate change researchers.
