MODIS/Terra Near Real Time (NRT) Surface Reflectance Quality Daily L2G Global 1km SIN Grid V005Entry ID: MOD09GST
Abstract: The MODIS Near Real Time (NRT) level-2G 1km surface reflectance data state QA product MOD09GST, is a restructured version of its primary input, the state QA data in MOD09_L2. This product summarizes the quality of the MOD09 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. Data Set Characteristics: Area: ~10 degrees x 10 degrees lat/long Image Dimensions: 1200 x 1200 rows/columns File Size: 10-20 MB Resolution: ~1000 meters Projection: Sinusoidal Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 2 Version-4 MODIS/Terra data are validated products. NOTE: These products are validated, meaning that product uncertainties are well defined over a range of representative conditions. Although there may be later improved versions, these data are ready for use in scientific publications still experimental in nature upon their initial release. Investigations are underway to assess the scientific validity of these products.

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.I... on comparison of C6 Operational and NRT Atmospheric and Land Products is posted at:http://lance3.modaps.eosdis.nasa.gov/data_products/comparison_atmos... and http://lance3.modaps.eosdis.nasa.gov/data_products/comparison_land.....
