Auchencorth Moss Atmospheric Observatory (AU) was established as EMEP (European Monitoring and Evaluation Program, Level 2/3) supersite for the UK in 2006. Long-term monitoring is led by NERC CEH (Centre for Ecology and Hydrology) with contributions from other organisations and research institutes including Ricardo AEA, BureauVeritas, NPL, the University of Birmingham and University of Edinburgh. In April 2014, the site was awarded WMO GAW regional station (World Meteorological Orgamisation Global Atmospheric Watch). In 2017 the site joined the ICOS network (Integrated Carbon Observation System).

Meteorological measurements at AU were initially made to assist with interpretation of the fluxes, and as such weren't installed with the intention of providing WMO standard measurements. Since 2014, AU has been moving towards these standards as well as enhancing instrumentation.

Similar measurements are also made at nearby Easter Bush Field site by the same team.
