Determination of total suspended solids distribution in Lake Taihu from Landsat Thematic Mapper data

摘要

The spectral reflectance of surface water bodies was measured with high spectral resolution radiometer. The water bodies were also sampled to assess the concentrations of total suspended solids and chlorophyll-a in laboratory. An exponential model using the reflectance ratio of TM3 and TM1 bands was derived for predication of the total suspended solids concentration. TM image of Lake Taihu was acquired at a different time. The distribution of total suspended solids in Lake Taihu was estimated and compared with the field measurements.
