Abstract

The POLDER instrument has been launched aboard the Japanese ADEOS platform in August 1996. In the paper, we shall describe the aerosols retrieval algorithms both over land surfaces and ocean surfaces. Over ocean surfaces, we use the classical method based on the spectral dependence of the near IR radiances. The directional effect is used to mean the results and to avoid the sunglint. The polarized radiances give some information about the refractive index. Over land surfaces, it has been suggested long ago that polarization could offer a powerful tool for remote main reason why some spectral bands of the instrument have been devoted to polarization measurements. The algorithm uses the bidirectional polarized observations within a large range of scattering angles in three spectral bands centered on 443, 670 and 865 nm. Calibration validation phase should be over around the middle of 1997, then the validation of the POLDER 'scientific results' will start. Preliminary results concerning aerosols retrieval will be presented: global aerosol optical thickness map, microphysics and comparison with in-situ measurements.
