Abstract
Total suspended matter concentration (TSM) algorithms for ocean color sensors use empirical relationship between satellite-retrieved remote sensing reflectances and TSM. However the estimated-TSM has no enough accuracy because the reflectance at visible bands has error after atmospheric correction in high turbid area. The purpose of this study is to estimate simultaneously total suspended matter concentration, aerosol optical thickness and Angstrom exponent using three bands at near infrared from MODIS/Aqua and SeaWiFS data. We applied this scheme to MODIS/Aqua and SeaWiFS data, and satellite-derived TSM were compared with ship-observed TSM dataset in Yellow Sea and East China Sea. RMSE of TSM was 0.338 in log-log coordinates and correlation coefficient was 0.850. The scheme was better than Clark’s or Tassan’s TSM algorithm.
