Effects of atmospheric aerosol on climate, measured by sun and star photometer

Updated 2002-02-01

In recent years, much attention has been directed towards understandig the effects of aerosols on a variety of processes in the earth atmosphere. Aerosols play an integral role in limiting visibility, they serve as nuclei for the formation of fog and cloud droplets, they affect the earth radiative budget, and thus climate, both directly and indirectly, and they inhibit the propagation of electromagnetic radiation. The Arctic aerosols, especially Arctic Haze and tropospheric ice crystals possible have important climatic and ecological and global change implications. Since 1991 Sun photometer observations of the polar atmopheric aerosol have been performed at the Koldewey Station in Ny-Aalesund, Spitzbergen. In order to complete the coverage and quality of measurements during the polar night a high sensitive Star photometer is installed since January 1996. Both measurements, the daylight Sun photometer measurements and night Star photometer measurements will be continued.
