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.
MYD09A1 provides
Bands 1-7 at 500-meter resolution in an 8-day gridded level-3 product in the
Sinusoidal projection. Each MYD09A1 pixel contains the best possible L2G
observation during an 8-day period as selected on the basis of 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.
