OBSERVATIONS OF POLARIZED ZENITH-SKY RADIANCES DURING TWILIGHT WITH APPLICATION TO AEROSOL PROFILE EVALUATION

摘要

Vertical profile of aerosol characteristics could be deduced using measurements of zenith-sky polarized radiance at twilight. It is proposed an algorithm for retrieval of aerosol profile using measurements of degree of polarization at 800 nm for solar zenith angles from 90° to 96°. Retrieval errors are analyzed. Preliminary results of measurements of degree of polarization at a few observational sites are discussed.
