Advances in Research Products From CALIPSO: Optical Depth Direct Retrieval Over Ocean, Water Clouds and Land
Résumé
We present a general overview of the recent advancement we made on direct optical thickness retrieval of optically thin atmospheric features (aerosol, cirrus clouds) using CALIPSO lidar return from dense targets (liquid water clouds, ocean and land surface). Data fusion with this direct optical thickness retrieval and collocated passive remote sensing measurements (e.g., PARASOL) will enable an AERONET-like of retrieval concept from A-train measurements. We first present the theoretical advances we made on lidar equation for surface and its significance for ocean color research, then the status of our advancement on aerosol optical depth retrieval along with, an example of cirrus optical depth retrieval over the ocean and a few words on over land AOD retrieval.
