Paper Abstract

This paper is aiming at the problem that the MODIS surface reflectance product (MOD09) does not offer an accurate aerosol correction for inland water, for the constraints of MODIS atmospheric correction algorithm. In-situ data collected in Taihu Lake and Yuqiao Reservoir were used to validate and assess the quasi-synchronous MOD09 product. The results showed that there is linear relationship on the whole between MOD09 bands and in-situ data in inland water with acceptable deviation level. The reason for the deviations is analyzed primarily and a simple correction for MOD09 product in Lake Taihu is introduced based on bands calculation. The results also illustrated that it is possible to monitor inland water quality globally with MOD09 product by providing validation evidence in typical inland waters. And it would be most accurate by using bands ratio algorithm for the water quality retrieval using MOD09. The validation is also important to improve atmospheric algorithms of MODIS.
