Google Earth Engine ——MYD09GA.006 Aqua 地表反射率 Daily Global 1km and 500m在没有大气散射或吸收的情况下在地

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. MYD09GA version 6 provides bands 1-7 in a daily gridded L2G product in the sinusoidal projection, including 500m reflectance values and 1km observation and geolocation statistics.

MODIS表面反射率产品提供了在没有大气散射或吸收的情况下在地面测量的表面光谱反射率的估计。低层数据经过了大气气体和气溶胶的校正。MYD09GA第6版在正弦投影的每日网格化L2G产品中提供了波段1-7，包括500米反射值和1公里观测和地理位置统计。
