Aerosols, Clouds, and Trace gases Research InfraStructure Network (ACTRIS)

ACTRIS Finland is a research infrastructure project focusing on the observation and analysis of atmospheric aerosols, cloud-related variables such as water content (ice and liquid states) and short-lived trace gases. At the moment, ACTRIS Finland is part of the EU FP7 project ACTRIS (Aerosols, Clouds, and Trace Gases Research Infrastructure Network) coordinated by the CNRS (France) and the CNR (Italy), whose long-term goal is to establish a permanent, standardised pan-European measurement network. The Finnish stations included in the ACTRIS infrastructure (the SMEAR stations, the Sammaltunturi measuring station) are run by the University of Helsinki and the Finnish Meteorological Institute.
