SMEAR - Station for Measuring Ecosystem-Atmosphere Relations

The SMEAR station was added to the Varrio Subartic Research Station in 1991 to measure pollution levels in the area, especially ones originating from the Kola Peninsual in Russia. The initial measurements focused on sulphur dioxide but during the 90s the scope of measurements were significantly augmented. Today, among other things, the SMEAR station measures the weather, aerosols, nonorganic gases in the atmosphere, the gas circulation and its relationship to the growth of forests.

This data helps scientists determine the complex interaction between the forest and changes in the atmosphere. The station is maintained by both the Department of Forest Ecology and the Department of Physical Sciences at the University of Helsinki. A similar SMEAR station (II) is located also at the Hyytiälä Forestry Field Station in Juupajoki, Southern Finland.
