The Atmospheric Research Centre of Eastern Finland studies atmospheric fine particles and their effects on climate and health. The following methods are applied related to research on fine particles and climate:

  • Atmospheric Radiation: We analyze satellite data on atmospheric aerosols. Furthermore, we study the impact of atmospheric particles on radiative transfer as a part of international AERONET and SolRad -Net –networks, and we develop a global UV radiation monitoring and forecasting system. Particles at different heights of the troposphere are examined with lidar measurements.
  • Atmospheric Modelling: We analyze laboratory and field measurements using both local and global scale models. Moreover, we do applied model research on, e.g. geoengineering. The Sectional Aerosol Model (SALSA) developed at the Kuopio Unit has been integrated into several international climate models.
  • Atmospheric Measurements: We study aerosol-cloud interactions and cloud formation with continuous measurements at the Puijo measurement station (SMEAR IV station). Furthermore, we organize intensive measuring campaigns at Puijo and participate in international campaigns elsewhere in Finland and abroad.
