MODIS/Terra Surface Reflectance Rolling-8-Day L3 Global 500m SIN Grid NRT

The MODIS/Terra Surface Reflectance Rolling-8-Day L3 Global 500m SIN Grid Near Real Time (NRT) product provides Bands 1-7 at 500-meter resolution in a daily rolling 8-day gridded level-3 product in the Sinusoidal projection. The short name of this product is MOD09A1N. Each MOD09A1N pixel contains the best possible L2G observation during an 8-day period as selected on the basis of high observation coverage, low view angle, the absence of clouds or cloud shadow, and aerosol loading. Science Data Sets (SDS) provided for this product include reflectance values for Bands 1-7, quality assessment, and the day of the year for the pixel along with solar, view, and zenith angles.

MODIS/Terra地表反射率滚动8日L3全球500米SIN网格近实时(NRT)产品提供了1-7波段在500米分辨率下的每日滚动8日网格化三级产品，采用正弦投影。该产品的简称是MOD09A1N。每个MOD09A1N像素均包含在一个8日周期内基于高观测覆盖率、低观测角度、无云或云影、以及气溶胶负载的最佳L2G观测结果。为该产品提供的科学数据集(SDS)包括1-7波段的反射率值、质量评估以及像素的年内日数，以及太阳、观测和天顶角度。
