Paper Abstract

To estimate aerosol properties, the PSR-1000 polarimeter measures the radiance of direct sunlight and the radiance and polarization of atmospheric light. PSR-1000 has been calibrated once a year by the Langley plot method at Mt. Haleakala Observatory in Maui Island, Hawaii, and so on. To improve the derivation of aerosol optical thickness, precise correction of molecular scattering and gaseous absorption is desired. Therefore the gaseous absorption by water vapor, O2 and NO2are reexamined at present. It is of interest to mention that PSR-1000 detects atmospheric particles over an urban area recorded among our long-term observations.
