Three separate algorithms: 1) Modified NIR-SWIR atmospheric correction, 2) Suspended sediment concentration (SSC), and 3) Diffuse attenuation coefficient at 490 nm, Kd (490) were developed and used for mapping SSC and Kd (490) for the East China natural waters. A geographic area located between 27-35°N and 119-125°N was selected to analyze wet (flood) and dry seasons from 2000 to 2015. Remote sensing acquisition has been realized using the MODIS/Terra and MODIS/Aqua satellite sensors. Results showed large differences between these seasons in terms of spatial pattern of SSC and Kd (490) levels: SSC and Kd (490) values were higher during the dry season than during the flood season in the most part of area for most of the area. The area with high SSC>80 gm-3 [or, correspondingly, Kd (490)>2.3 m-1.. View More»
