Abstract:
The MODIS Surface Reflectance products are 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.
The MOD09GQ product provides Band 1 and 2 data 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.

Version-5 MODIS/Terra Surface Reflectance products are validated, meaning that
product uncertainties are well defined over a range of representative
conditions. Although there may be later improved versions, these data are ready
for use in scientific publications.
