MYD09GQ.061 Aqua Surface Reflectance Daily Global 250m

  • The MODIS MYD09GQ dataset provides daily global surface reflectance at 250m resolution for bands 1 and 2.

  • This dataset is available from July 4, 2002, to October 14, 2025, and is provided by NASA LP DAAC at the USGS EROS Center.

  • The data are corrected for atmospheric effects and include quality assurance information.

  • The product is designed to be used with MYD09GA for additional quality and viewing geometry details.

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. MYD09GQ 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 MYD09GA where important quality and viewing geometry information is stored.
