abstract = " Suspended particulate matter (SPM) is one of the key issues in estuarine and coastal waters, which is widely used in water quality assessment, river erosion and siltation, and port engineering. The Wide-band Imaging Spectrometer (WIS) as one of the payloads mounted on the Tiangong-2 (TG-2) is a successor of spaceborne ocean color sensors. In this study, data from Geostationary Ocean Color Imager (GOCI) launched by Korean ocean satellite center (KOSC) and in situ measurements are used to compare and evaluate data products acquired by the TG-2/WIS. Comparison results show that the TOA reflectances of TG-2/WIS and GOCI agree well at visible and near-infrared bands. Atmospherically-corrected remote sensing reflectances (R rs ) from TG-2/WIS and GOCI have good correspondences from visible to near-infrared bands Their root mean square differences (RMSD) at 660 and 745 nm are less than 0.04 sr −1 , and the TG2/WIS observed R rs is slightly underestimated at 865 nm with the slope of 0.77. Moreover, the derived SPM concentrations from TG-2/WIS and GOCI data are quite approximate. It implies that the accuracy of TG-2/WIS data products can meet the need of marine environmental monitoring in estuaries and coastal regions. In addition, in contrast to other ocean color sensors, the TG-2/WIS may have greater potentials of water color applications, especially for meso- and small-scale phenomena and optically complex waters, due to its multi-bands and high spatial resolution advantages.",
