A Multi-Band Atmospheric Correction Algorithm for Deriving Water Leaving Reflectances over Turbid Waters from VIIRS Data

The current operational multi-band atmospheric correction algorithms implemented by NASA and NOAA for global remote sensing of ocean color from VIIRS (Visible Infrared Imaging Radiometer Suite) data are mostly based on the 2-band version SeaWiFS (Sea-Viewing Wide Field-of-View Sensor) algorithm. These generally use two NIR bands, one centered near 0.75 μm other 0.865 μm, a band ratio method deriving aerosol information. work quite well over open waters. However, water leaving reflectances turbid coastal waters frequently not derived. We describe here spectrum-matching algorithm using shortwave IR (SWIR) bands above 1 retrieving in visible data. SWIR 1.24, 1.61, 2.25 used process to obtain spectral information, which is subsequently extrapolated region derivation bands. present retrieval results four scenes acquired demonstrate that spatial coverages our can be improved significantly comparison with those retrieved If processing, potentially complimentary increase coverages.
