MYD09GQ.061 Aqua Surface Reflectance Daily Global 250m

  • MYD09GQ provides daily surface reflectance data at 250m resolution for bands 1 (red) and 2 (near-infrared) from the MODIS sensor on the Aqua satellite.

  • The data is corrected for atmospheric effects, offering an estimate of surface reflectance as if measured at ground level.

  • This product includes quality assurance information and observation details, and is best used in conjunction with MYD09GA for complete viewing geometry and quality assessments.

  • Data is available from July 4, 2002 to December 9, 2024 and is freely available for use, sale, or redistribution.

  • Users can access and analyze this dataset through Google Earth Engine using the provided code snippet.

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.
