Long-term monitoring of aerosol optical characteristics by using sky radiometer at Ny-Alesund, Svalbard

Sky radiometer measurement has been continued at Ny-Alesund, Svalbard (78.93N, 11.86E, Alt. 30 m) in the Arctic region, since March 2000. In this study, we present the temporal variation and the relationship of Angstrom parameters (i.e., aerosol optical thickness and Angstrom exponent) at Ny-Alesund...

Description
Summary:Sky radiometer measurement has been continued at Ny-Alesund, Svalbard (78.93N, 11.86E, Alt. 30 m) in the Arctic region, since March 2000. In this study, we present the temporal variation and the relationship of Angstrom parameters (i.e., aerosol optical thickness and Angstrom exponent) at Ny-Alesund. The results of long-term measurements show clear seasonal trends of the aerosol optical thickness at 0.5 μm with maximum in spring and minimum at the end of summer, and of the Angstrom exponent with temporal increase in spring to summer.
