Abstract:

PARASOL can be used in not only polarized measurements, but also intensity measurements. The intensity reflectance of typical land surfaces in PARASOL channels was analyzed, and dark dense vegetation (DDV) algorithm of PARASOL was developed. From PARASOL intensity measurements in the summer of 2006, the aerosol optical depth (AOD) was retrieved by the algorithm. By the comparison with Beijing Site of aerosol robotic network (AERONET), correlation coefficient was equal to 0.86, but when AOD was small, the retrieval error was large.

Key words: remote sensing, aerosol over land surface, polarization, dark dense vegetation
