Mission: The Finnish Meteorological Institute (FMI) has participated in the GAW programme since 1994. Their scientific focus is on clean air atmospheric composition or aerosols and trace gases as well as air quality. The Pallas-Sodanklya research programs are strongly integrated with ecosystem research.

Facility and Environs: The Arctic Research Centre and the Pallas Atmospheric Research station together form the Pallas-Sodankyla GAW station. Upper-air soundings, synoptic measurements, total ozone observations and ozone soundings are taken at Sodankyla whereas tropospheric air composition and related boundary-layer meteorology measurements are taken at Pallas. Due to the warming effect of the Gulf Stream the area is included in the boreal region. However, with regard to stratospheric meteorology, Sodankylä can be classified as an Arctic site, often lying beneath the middle or the edge of the stratospheric polar vortex and in the zone of polar stratospheric ozone depletion. Its strategic location, coupled with ready accessibility from all parts of the world, makes the ARC an excellent base for studying various themes of global change in a northern context. The ARC research sites belong to the Lapland Biosphere-Atmosphere Facility (LAP-BIAT), an infrastructure project through which the EU can fund visiting research groups.
