Paper Abstract

Polarized reflectance from POLDER measurements are used to infer cloud properties such as cloud phase (water, ice), cloud droplet size, and bidirectional reflectances. The results show that data from simulator of POLDER instrument carried on aircraft can be used to infer cloud phase and droplet sizes. The POLDER data from satellite can be used to detect cloud phase but difficult to infer droplet sizes due to less angular observations around rainbow feature. Initial results of satellite POLDER data shows the potential ability of cloud classification using polarization information combined with reflected intensity. Combining with reflected intensity, the multiangle observations of polarized reflectance can be used to discriminate scene types such as ice cloud, water cloud, thin cirrus over water cloud, aerosol over water cloud and sun glint.
