MODIS/Terra Surface Reflectance Daily L2G Global 1km and 500m SIN Grid V005

Version 005
  • Abstract
    The MODIS Surface Reflectance products provide 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. MOD09GA 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-meter Science Data Sets provided for this product include reflectance for Bands 1-7, a quality rating, observation coverage, observation number, and 250-meter scan information. 1-kilometer Science Data Sets provided include number of observations, quality state, sensor angles, solar angles, geolocation flags, and orbit pointers. Version-5 MODIS/Terra Surface Reflectance products are Validated Stage 2, meaning that accuracy has been assessed over a widely distributed set of locations and time periods via several ground-truth and validation efforts. Change Points of Interest Reduced number of data products: MOD09GST, MOD09GHK, MODMGGAD, MODPT1KD, and MODPTHKM encapsulated within MOD09GA Revised methodology for choosing first layer observation Reduced file volume: internal compression V005 Data Set Characteristics: Temporal Coverage: February 24, 2000 - March 30, 2017 Area: ~10 degrees x 10 degrees lat/long File Size: ~85 MB Projection: Sinusoidal Data Format: HDF-EOS 1-km Data Group Dimensions: 1200 x 1200 rows/columns 1-km Data Group Science Data Sets: (SDS HDF Layers) 9 (1) 500-m Data Group Dimensions: 2400 x 2400 rows/columns 500-m Data Group Science Data Sets: (SDS HDF Layers) 12 (2)
