MODIS/Terra Surface Reflectance Daily L2G Global 1km and 500m SIN Grid V061

The MOD09GA Version 6.1 product provides an estimate of the surface spectral reflectance of Terra Moderate Resolution Imaging Spectroradiometer (MODIS) Bands 1 through 7, corrected for atmospheric conditions such as gasses, aerosols, and Rayleigh scattering. Provided along with the 500 meter (m) surface reflectance, observation, and quality bands are a set of ten 1 kilometer (km) observation bands and geolocation flags. The reflectance layers from the MOD09GA are used as the source data for many of the MODIS land products. Known IssuesMOD09GA 6.1版产品可估算Terra中等分辨率成像光谱辐射计（Terra Moderate Resolution Imaging Spectroradiometer, MODIS）第1至7波段的地表光谱反射率，并针对气体、气溶胶及瑞利散射等大气影响因素完成校正。该产品随附500米（m）分辨率的地表反射率、观测波段与质量波段，同时配套提供十组1千米（km）分辨率观测波段及地理定位标识。MOD09GA的反射率图层可作为诸多MODIS陆地产品的源数据使用。已知问题
