ENVINET (European network for arctic-alpine multidiciplanary environmental research) is a research infrastructure network focusing on multidisciplinary environmental research in Europe. The network involves representatives from 18 environmental research infrastructures from the European Alps to the Arctic, representatives of their users and representatives from relevant international organizations and networks. The participating infrastructures cover a broad range of environmental sciences primarily within atmospheric physics and chemistry as well as marine and terrestrial biology.
The ENVINET project directory covers data and observation activities at these stations.

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.
Monitoring of direct deposition. Project is run by Finnish Meteorological Institute (FMI).
For a two year period daily samples of selected trace gases (nitric acid, sulfur dioxide and ammonia) and aerosol compounds (sulfate, nitrate, oxalate and ammonium) are determined with filter packs at the Sonnblick Observatory. The measurements will be used to identify the seasonal cycles of the selected trace gases and aerosol compounds at the 3 km level above Central Europe. Especially during the cold season previous measurements showed that samples collected at the Observatory represent free tropospheric air masses. Together with wet deposition measurements carried out at the site scavenging parameters are calculated.
