MOD09GQ.061 Terra Surface Reflectance Daily Global 250m

    • The MODIS Surface Reflectance products estimate surface spectral reflectance as measured at ground level, corrected for atmospheric effects.

    • MOD09GQ version 6.1 provides bands 1 and 2 at a 250m resolution in a daily gridded L2G product.

    • This dataset is available from 2000-02-24 to 2025-10-14 with a daily cadence.

    • MODIS data acquired through the LP DAAC have no restrictions on subsequent use.

    • The dataset includes bands for surface reflectance, quality assurance, and observation information.

    Description

    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. MOD09GQ version 6.1 provides bands 1 and 2 at a 250m resolution in a daily gridded L2G product in the Sinusoidal projection, including a QC and five observation layers. This product is meant to be used in conjunction with the MOD09GA where important quality and viewing geometry information is stored.
