MODIS/Terra Surface Reflectance 8-Day L3 Global 500m SIN Grid V005Entry ID: MOD09A15
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.
MOD09A1 provides Bands 1???7 at 500-meter ... resolution in an 8-day gridded level-3 product in the Sinusoidal projection. Each MOD09A1 pixel contains the best possible L2G observation during an 8-day period as selected by high-observation coverage, low-view angle, the absence of clouds or cloud shadow, and aerosol loading. Science Data Sets provided for this product include reflectance values for Bands 1???7, quality assessment, and the day of the year for the pixel along with solar, view, and zenith angles.
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.
