MODIS/Aqua Near Real Time (NRT) Surface Reflectance Daily L2G Global 250m SIN Grid (C005)
Entry ID: MYD09GQ


Summary
Abstract: The MODIS Near Real Time (NRT) Surface Reflectance products are an estimate of the surface spectral reflectance as it would be measured at ground level in the absence of atmospheric scattering or absorption. Low-level data are corrected for atmospheric gases and aerosols, yielding a level-2 basis for several higher-order gridded level-2 (L2G) and level-3 products. MYD09GA provides Bands 1???7 in a daily gridded L2G product in the Sinusoidal projection, including 500-meter reflectance values and 1-kilometer observation and geolocation statistics. 500-m Science Data Sets provided for this product include reflectance for Bands 1???7, a quality rating, observation coverage, observation number, and 250-m scan information. 1-kilometer Science Data Sets provided include number of observations, quality state, sensor angles, solar angles, geolocation flags, and orbit pointers.V005 Data Set Characteristics:Area: ~10 degrees x 10 degrees lat/long Image Dimensions: 1-km: 1200 x 1200 rows/columns; 500-m 2400 x 2400 rows/columns File Size: ~85 MB Resolution: 250 meters Projection: Sinusoidal Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 5V004 Data Set Characteristics (decommissioned):Area: ~10 degrees x 10 degrees lat/long Image Dimensions: 4800 x 4800 rows/columns File Size: ~280 MB Resolution: 250 meters Projection: Sinusoidal Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 5V003 Data Set Characteristics (decommissioned):Area: ~10 degrees x 10 degrees lat/long Image Dimensions: 4800 x 4800 rows/columns File Size: ~280 MB Resolution: 250 meters Projection: Sinusoidal Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 5

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... and http://lance3.modaps.eosdis.nasa.gov/data_products/comparison_land.....
