Remote Sensing of Atmosphere-Ocean Systems in the UV: How Can Polarimetery Help Distinguish Reflectance Variations Caused by Absorbing Aerosols from Variations Caused by CDOM?
Chowdhary, J. and Cairns, B. (04-May-16)
Using Multispectral, Multiangle Polarimetric Remote Sensing Observation for Ocean Color Retrievals: Studies Performed for the Pre-Aerosol, Clouds, and ocean Ecosystem (PACE) Mission
Chowdhary, J., Knobelspiesse, K.D., and Cairns, B. (26-Feb-16). The high sensitivity of polarized light scattered by suspended particles to the properties of these particles has successfully been exploited during the last 40+ years to obtain unique information of aerosols in planetary atmospheres from polarimetry. In addition, promising results have been obtained regarding the sensitivity of polarimetric observations to the properties of marine particulates. This has led to the consideration of adding a polarimeter to the PACE mission. Here, we discuss 3 types of polarization studies performed for this mission.
