MYD09GST

MODIS/Aqua Surface Reflectance Quality Daily L2G Global 1km SIN Grid NRT

NRT

The MODIS/Aqua Surface Reflectance Quality Daily L2G Global 1km SIN Grid Near Real Time (NRT) product, short name 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.

Processing Level

Quality Overall NRT products match to operational with some expected minor differences from use of different ancillaries and ephemeris. There aren't any data gaps or data artifacts. Information on comparison of C5 Operational and NRT Atmospheric Products is posted at: http://lance.modaps.eosdis.nasa.gov/data_products/comparison.html. Information on comparison of C6 Operational and NRT Atmospheric and Land Products is posted at: http://lance3.modaps.eosdis.nasa.gov/data_products/comparison_atmos.html and http://lance3.modaps.eosdis.nasa.gov/data_products/comparison_land.html.
