MODIS/Aqua Surface Reflectance Daily L2G Global 1km and 500m SIN Grid NRT

The MODIS/Aqua Surface Reflectance Daily L2G Global 1km and 500m 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.MYD09GA provides Bands 1-7 in a daily gridded L2G product in the Sinusoidal projection, which includes 500-meter reflectance values and 1-kilometerobservation and geolocation statistics. 500-meter Science Data Sets provided by this product include reflectance for Bands 1-7, a quality rating, observation coverage, observation number, and 250-meter scan information.1-kilometer Science Data Sets provided include number of observations, quality state, sensor angles, solar angles, geolocation flags, and orbit pointers.

MODIS/Aqua表面反射率每日L2G全球1公里和500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，按地面水平测量。低层数据经过大气气体和气溶胶的校正，为多个高级次格网L2G和L3产品提供了2级基础。MYD09GA产品以正弦投影提供了每日格网L2G产品中的1-7波段，包括500米反射率和1公里的观测与地理定位统计信息。该产品提供的500米科学数据集包括1-7波段的反射率、质量评级、观测覆盖率、观测编号和250米扫描信息。1公里科学数据集包括观测数量、质量状态、传感器角度、太阳角度、地理定位标志和轨道指针。
