Summary
Abstract: This product has been decommissioned.

This MODIS 250-meter surface reflectance two-band product is computed from
MODIS level-1B land Bands 1 and 2 (centered at 648 nanometers and 858
nanometers, respectively). The product is an estimate of the surface spectral
reflectance for each Band as it would be measured at ground level if there were no atmospheric scattering or absorption. A correction scheme reducing the
effects of atmospheric gases, aerosols, and thin cirrus clouds is applied to
all non-cloudy pixels passing level-1B quality control. Data from Bands 3
through 7 (500-meter resolution) are not included in the MOD09GQK product.
This product is processed globally every day, using level-2 250-meter pointer
files to place level-2 surface reflectance on a geographic grid. A given pixel
may have more than one value, because every observation overlapping the tile
being processed is used as input. All of the values are stored in a unique
Science Data Set Lone Array, but only the first observed value is used in the
surface reflectance science data sets. Quality assurance data for the MOD09GQK
product are provided at different levels of detail including at the individual
pixel level, at each Band and each resolution level, and at the level of the
entire file.
