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.
MYD09GQ provides Bands
1 and 2 at a 250-meter resolution in a daily gridded L2G product in
the Sinusoidal projection. Science Data Sets provided for this product
include reflectance for Bands 1 and 2, a quality rating, observation
coverage, and observation number. This product is meant to be used in
conjunction with the MOD09GA where important quality and viewing
geometry information is stored.
