The Particulate Observing Scanning Polarimeter (POSP) is a cross-track multispectral polarimetric scanning imager onboard both GaoFen-5(02) and DQ-1 satellites. POSP has a field of view +/- 50 degree with a nadir resolution of ~6.4 km and a swath of ~1850 km, and it measures the stokes vector (I, Q, U) at nine spectral bands from UV to SWIR, specifically 380, 410, 442, 490, 670, 865, 1610, and 2250 nm. Previous study has shown the UV-VIS-NIR-SWIR single-view polarimetric measurements from POSP/GF-5(02) could provide reliable information content for aerosol and surface characterization. In this study, we will describe the synergetic utilization of POSP measurements from GF-5(02) morning and DQ-1 afternoon satellites in order to enhance the capability to retrieve aerosol and surface properties.
