• Polarized sky radiance
• Aerosols
• AOD
• Albedo
• All-sky camera

All-sky distributions of the polarized radiance are measured using an automated fish-eye camera system with a rotating polarizer For a large range of aerosol and surface albedo situations the influence on the degree of polarization and sky radiance is investigated The range of aerosol optical depth and albedo is 0 05-0 5 and 0 1-0 75 respectively For this range of parameters a reduction of the degree of polarization from about 0 7 to 04 was observed The analysis is done for 90 scattering angle in the principal plane under clear sky conditions for a broadband channel of 450 +/- 25 nm and solar zenith angles between 55 degrees and 60 degr
