The Pallas-Sodankylä Research Station consist of a clean air research station in Pallas and the Arctic Space Centre in Sodankylä. The distance between the two sites is 125 km. Both of these units are hosted and owned by the Finnish Meteorological Institute.
Pallas is located in western Lapland (67°58’ N, 24°07’ E) in Pallas fell. The station is part of a national park with limited access to the public. The Sodankylä facility (67°22’ N, 26°39’ E) is located in central Lapland within the boreal forest region. The station is not part of any national park, but the area (c. 2 km2) is dedicated to atmospheric and geological research, and therefore has limited public access. The area is surrounded by forest and wetland owned by the Finnish government.
Grey colours are WMO Climate Normals including maximum and minimum values. Blue colours are individual years.
Climate data for the stations where extracted via Copernicus Climate Data Store, from the global gridded reanalysis product: ERA5 monthly averaged data on single levels from 1940 to present.

The area around Pallas Station is boreal forest. Willow grouse, rabbit, and reindeer are the most typical animals. Sodankylä Station is located at a river bank in the middle of a boreal forest. Black grouse, rabbit, and reindeer are the most typical animals.
The Finnish Meteorological Institute has a long history of atmospheric monitoring at Pallas; the first weather station was established near Lake Pallasjärvi in 1935. The measurements of atmospheric composition were started in 1991, and the Sammaltunturi station was established as a node of the Pallas–Sodankylä Global Atmosphere Watch (GAW) station in 1994. The Sodankylä Station was established in 1949, but continuous homogenized synoptic weather records have been made since 1908. The facility consists currently of multiple buildings (1500 m2 in total).
The Pallas station consists of research infrastructure for monitoring and studying the atmosphere, ecosystems and their interactions. The research area hosts four sub-sites with different research programs within a 5 km radius, covering different micro-environments: top of an arctic fell, an elevated forest clearing, a forest site and a subarctic fen. The Sodankylä facility hosts programs exploring upper-air chemistry and physics, atmospheric column measurements, snow/soil physics, biosphere-atmosphere interaction, and satellite calibration-validation studies.
