A method of ocean color data processing using the combined near-infrared (NIR) and shortwave infrared (SWIR) bands for atmospheric correction Moderate Resolution Imaging Spectroradiometer (MODIS) on Aqua is proposed. MODIS-Aqua has been producing high quality products in open oceans, but there are still some significant errors derived coastal regions. With proposed NIR-SWIR algorithm, MODIS can be processed standard algorithm whereas turbid waters region SWIR executed. The water index developed by Shi Wang (2007) (Remote Sens. Environ. 110, 149-161 (2007)) computed prior to identification productive and/or where operated. For non-turbid (discriminated criterion), algorithm. tested evaluated. Two examples from measurements along U.S. China east coast regions show improved with new approach. In particular, no obvious discontinuities between NIR methods. Therefore, approach processing, good both clear (open) oceans as well waters.
