Abstract: This study makes a contribution to the quality assessment of the VIIRS radiometric products through comparing with concurrent data from the moderate-resolution imaging spectro radiometer(MODIS, NASA) sensor.The results show that VIIRS and MODIS have similar observing capability in near-shore waters, while the remote-sensing reflectance(Rrs) of VIIRS is higher than that of MODIS in turbid waters. This paper provides the validation results for VIIRS-derived water products using match-ups between the satellite and ship-borne in-situ data applied for the Bohai Sea, especially focusing on remote sensing reflectance( Rrs). The match-ups show that the current VIIRS atmospheric corrections are systematically under the estimation over turbid waters. The APD of Rrs from VIIRS becomes larger when the band is away from NIR and the TSM rises.
