US National Aeronautics and Space Administration (NASA) Terra Moderate Resolution Imaging Spectroradiometer (MODIS) Level 2 Surface Reflectance Daily Product (MOD09GA), Version 6.1

MOD09GA is part of the Moderate Resolution Imaging Spectroradiometer (MODIS) suite of data products. It specifically provides estimates of the global surface spectral reflectance of MODIS bands 1-7 at 500 m and 1 km resolution. Observations are corrected for atmospheric conditions such as gases, aerosols, and Rayleigh scattering, which allows for more accurate measurements of surface properties.
