Column aerosol optical properties based on the sky-radiometer measurement at Ny-Alesund in the Arctic spring of 2006 and 2007
Sky-radiometer measurements have been performed in Ny-Alesund with Prede POM-01 since March 2000, and followed by POM-02 since May 2004. Aerosol optical properties, i.e., optical thickness, single scattering albedo and refractive index for selected wavelengths at 400, 500, 675, 870 and 1020 nm, and...
