摘要：Suspended sediment load plays an important role in coastal processes. They can be used as a proxy for water quality variables such as turbidity, pollution and primary production. The large spatial and temporal variability of coastal environments, e.g. Amazon River mouth, makes it difficult the acquisition of spatially meaningful in situ data on suspended sediments. To overcome that problem the relationship between suspended sediment and the reflectance measured by remote sensors has been used to estimate and to map those properties over coastal waters. Taking this fact into consideration, the 260 m band (630 - 690 nm) of WFI/CBERS-2 may be added as alternative data source for coastal water monitoring even so it was not aimed to that application. In the next years, however, new satellites (CBERS 3-4) from the China-Brazil Earth Resources Satellite program will be launched with the same spectral resolution but with improvements in the spatial resolution (73 m) allowing for a better imaging of coastal processes. Taking the previous aspects into consideration, in this paper, WFI/CBERS 2 band (630 - 690 nm) and 250 m band (620 – 670 nm) of the MODIS/TERRA data are compared to assess the suitability of future coastal studies. Previous results show a considerable correlation between these two bands
