Remote Sensing of Aerosols and Clouds
The Remote Sensing of Aerosols and Clouds group consists of experts in remote sensing of aerosols and clouds, ultraviolet radiation and aerosols, and cryosphere-atmosphere interactions. The research professor of the group is prof. Gerrit de Leeuw and the group leader is Dr. Outi Meinander.
The Remote Sensing of Aerosols and Clouds scientists develop algorithms for the retrieval of aerosol and cloud properties, and surface reflectance, using data measured by radiometers on board satellites, in particular AATSR aboard ENVISAT and ATSR-2 aboard ERS-2. Results from these and other instruments (e.g., MERIS, MODIS, OMI and in the future SLSTR, OLCI, TROPOMI) are used in studies on the effects of aerosols on the Earth radiation balance, air quality, the occurrence of volcanic ash and on emissions of aerosols and their precursor gases. Together with satellite-retrieved cloud information the aerosol data are used in aerosol-cloud interaction studies and their effect on climate.
Ground-based measurements are made for validation of satellite products of aerosols and ozone. The group has a strong expertise on measurements of ozone column concentrations and UV radiation, including Arctic and Antarctic research. The UV research includes also effects of UV radiation on material aging, health, plant growth and planning of build environment.
The co-operative research on atmosphere-cryosphere interactions include surface albedo measurements and effects of deposition of dust, and black carbon and organic carbon aerosols on snow properties.
