Distribution maps of aerosol's three optical parameters from POLDER's multi-directional data

It is possible to retrieve three aerosol optical parameters, namely, its optical thickness /spl tau//sub n/(500) at the wavelength of 500 nm, /spl Aring/ngstro/spl uml/m exponent a, and real part of refractive index Nr, from ADEOS/POLDER data sets by analyzing their directional reflectance and polarization information. In this retrieval we applied the directional R-P (Reflectance-Polarization) algorithm to the POLDER 865-nm band data and the average distribution maps of the three aerosol optical parameters were presented over the oceans from the Indian Ocean to the western Pacific Ocean during April 1-30, 1997.
