‌Located on the west coast of Ireland, the Ryan Institute's Mace Head Atmospheric Research Station in Carna, County Galway has been a site for aerosol measurements since 1958. The location is unique in Europe, offering westerly exposure to the North Atlantic ocean (clean sector, 180 degrees through west to 300 degrees) and the opportunity to study atmospheric composition under Northern Hemispheric background conditions as well as European continental emissions when the winds favour transport from that region.

Ryan Institute's Mace Head Atmospheric Research Station is a part of a number of international research networks including the Advanced Global Atmospheric Gases Experiment (AGAGE), the Atmospheric/Ocean Chemistry Experiment (AEROCE), World Meteorological Organisation/Global Atmospheric Watch (WMO/ GAW), Tropospheric Ozone Research (TOR, a EUROTRAC project), Budget of Ozone over the Atlantic (BOA) and the Climate Monitoring and Diagnostics Laboratory/National Oceanic and Atmospheric Administration (CMDL/NOAA) co-operative flask sampling network.
