MODIS/Aqua Near Real Time (NRT) Surface Reflectance Daily L2G Global 500m SIN Grid (C005)Entry ID: MYD09GHK
Abstract: The MODIS Near Real Time (NRT) Surface Reflectance Daily L2G Global 500m SIN Grid product, MYD09GHK, is a seven-band product computed from the MODIS Level 1B land bands 1-7. The product is an estimate of the surface spectral reflectance for each band as it would have been measured at ground level if there were no atmospheric scattering or absorption. The correction scheme includes corrections for ... the effect of atmospheric gases, aerosols, and thin cirrus clouds; it is applied to all Level 1B pixels that pass the Level 1B quality control. The correction uses band 26 to detect cirrus clouds, the approach used in MYD04 and MYD05 for water vapor, aerosol correction, and NCEP for ozone; the best available climatology data are used if the MODIS water vapor, aerosol, or ozone products are unavailable.The Level 2G surface reflectance product is the input for the generation of several land products: 8-day Surface Reflectance, Vegetation Indices (VIs), Bidirectional Reflectance Distribution Function (BRDF), thermal anomaly, snow/ice, and Fraction of Photosynthetically Active Radiation/Leaf Area Index (FPAR/LAI).V004 Data Set Characteristics: Area: ~10 degrees x 10 degrees lat/long Image Dimensions: 2400 x 2400 rows/columns File Size: ~208 MB Resolution: ~500 meters Projection: Sinusoidal Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 10V003 Data Set Characteristics: Area: ~10 degrees x 10 degrees lat/long Image Dimensions: 2400 x 2400 rows/columns File Size: ~208 MB Resolution: ~500 meters Projection: Integerized Sinusoidal Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 10

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.
