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

The MODIS/Aqua Surface Reflectance Daily L2G Global 250m SIN Grid Near Real Time (NRT) product is 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.MYD09GQ provides Bands 1 and 2 at a 250-meter resolution in a daily gridded L2G product in the Sinusoidal projection. Science Data Sets provided for this product include reflectance for Bands 1 and 2 a quality rating observation coverage and observation number. This product is meant to be used in conjunction with MYD09GA where important quality and viewing geometry information is stored.

MODIS/Aqua表面反射率每日L2G全球250米SIN网格近实时（NRT）产品是对地表光谱反射率的估计，该反射率在无大气散射或吸收的情况下，理论上在地表水平测量得到。低层数据经过大气气体和气溶胶的校正，从而为多个高阶格网化L2G和L3产品提供了二级基础。MYD09GQ产品在正弦投影中以每日格网化L2G产品的形式，提供了1号和2号波段的数据，分辨率为250米。为此产品提供的数据集包括1号和2号波段的反射率、质量评级、观测覆盖范围和观测编号。该产品旨在与存储重要质量和视几何信息的MYD09GA产品结合使用。
