In this study, field data such as the concentration of total suspended matter (TSM) in Hangzhou Bay and its adjacent areas in Hangzhou’s coastal waters were observed, meanwhile, hyperspectral remote snesing data were measured with SVC GER1500 spectrometer during four cruises carried out on 20th, 22nd, 23rd and 24th July 2010. The coastal water-leaving refectance of HICO was simulated from in situ hyperspectral remote sensing spectra. The normalized peak area of remote sensing reflectance in the near-infrared region was applied to retrieving TSM after the spectra of simulated HICO were analyzed, as well as the application of single band model and band ratio model. The result indicated that the band ratio algorithm of Rrs(724.84)/Rrs(461.36) of HICO could be used to retrieve TSM in Hangzhou Bay. This study is helpful to retrieving TSM in coastal waters using HICO.
