Pallas-Sodankylä, GAW station, Northern Finland

Updated 2013-02-02

GAW serves as an early warning system to detect further changes in atmospheric concentrations of greenhouse gases and changes in the ozone layer, and in the long-range transport of pollutants, including acidity and toxicity of rain as well as the atmospheric burden of aerosols.

This is a National Implementation Plan (NIP) project
