Global Atmosphere Watch (GAW) is the World Meteorological Organization's (WMO) global programme for monitoring and assessing chemical composition and related physical characteristics of the global background atmosphere.
The Finnish Meteorological Institute (FMI) has participated in the GAW programme since 1994. The Arctic Research Centre and the Pallas Atmospheric Research station together form the Pallas-Sodankylä GAW station. Upper-air soundings, synoptic measurements, total ozone observations and ozone soundings are taken at Sodankylä and tropospheric air composition and related boundary-layer meteorology measurements at Pallas.
The Pallas air quality monitoring station also participates in the Arctic Monitoring and Assessment Programme (AMAP), in the Co-operative programme for monitoring and evaluation of the long range transmission of air pollutants in Europe (EMEP) and a in a three-year EU-funded CORE project.
