Description

The MODIS/Aqua Surface Reflectance Daily L2G Global 250m SIN Grid Near Real Time (NRT) product, short name MYD09GQK, provides MODIS bands 1 and 2, daily surface reflectance at 250 m resolution. The product is an estimate of the surface spectral reflectance for each band as it would have been measured at ground level if there were no atmospheric scattering or absorption. The quality information for this product is provided at three different levels of detail: for individual pixels for each band and each resolution and for the whole file.
