MODIS/Aqua Surface Reflectance Quality Daily L2G Global 1km SIN Grid
Entry ID: MYD09GST

Abstract: The MODIS Near Real Time (NRT) level-2G 1km surface reflectance data state QA product MYD09GST, is a restructured version of its primary input, the state QA data in MYD09_L2. This product summarizes the quality of the MYD09 products, specifically atmospheric and other correction states. The product contains quality assurance data pertaining to cloud and cloud shadow, land and water designations, aerosols, and the data source of corrections performed on the file. The data set also contains the number of observations for each pixel.
