MODIS/Aqua Surface Reflectance Daily L2G Global 250m SIN Grid NRT

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.

MODIS/Aqua地表反射率每日L2G全球250米SIN网格近实时(NRT)产品，简称MYD09GQK，提供了MODIS第1和第2波段，以250米分辨率每日地表反射率。该产品是对每个波段地表光谱反射率的估计，若在无大气散射或吸收的情况下，该反射率应与地面测量值相吻合。该产品的质量信息以三个不同详细程度提供：针对每个波段和每个分辨率的单个像素，以及整个文件的质量信息。
