Spatial and Temporal Distributions of Suspended Sediment Contents in the Yangtze River Estuary Using the CMODIS Image Data from China''s SZ-3 Spacecraft
神舟三号CMODIS数据获取长江口悬浮泥沙含量的时空分布

Spatial and temporal distributions of suspended sediment concentrations are greatly important for analyzing the deposition and erosion variety of the estuary and coast,evaluating the material fluxes from river to sea,and studying oceanic sediment velocity and environment.The spectrometry imagery technology includes three kinds of spatial,radiation and spectral information.The Chinese Moderate Resolution Imaging Spectroradiometer(CMODIS) with 34 bands was loaded on the China's SZ-3 spacecraft on March 25,2002.Making use of the CMODIS data,this paper presents the retrievals of the suspended sediment concentrations and its spatial and temporal distributions in the Yangtze River estuary with the field measurements.
