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.
MYD09Q1 provides Bands 1
and 2 at 250-meter resolution in an 8-day gridded level-3 product in the
Sinusoidal projection. Each MYD09Q1 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 and 2, and a quality rating.
