MODIS/AQUA MYD09Q1 Surface Reflectance 8-Day L3 Global 250m

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, yielding a level-2 basis for several higher-order gridded level-2 (L2G) and level-3 products. Information on individual MODIS Land Surface Reflectance Products along with improvements/changes for Verson 6 are available at: https://lpdaac.usgs.gov/dataset_discovery/?f[0]=im_field_dataset_version%3A32&f[1]=im_field_product%3A10MODIS地表反射率产品（MODIS Surface Reflectance Products）可估算地表光谱反射率，模拟无大气散射与吸收情况下地面实测的反射率数值。其低层数据已针对大气气体与气溶胶完成校正，可为多款高阶网格化二级（L2G）及三级产品提供二级数据基础。 有关各款MODIS陆地地表反射率产品以及第6版的更新与变更信息，可通过以下链接获取：https://lpdaac.usgs.gov/dataset_discovery/?f[0]=im_field_dataset_version%3A32&f[1]=im_field_product%3A10
