MODIS/Aqua Atmospherically Corrected Surface Reflectance 5-Min L2 Swath 250m, 500m, 1km NRT

The MODIS/Aqua Atmospherically Corrected Surface Reflectance 5-Min L2 Swath 250m, 500m, 1km NRT, short name MYD09, is computed from the MODIS Level 1B land bands 1, 2, 3, 4, 5, 6, and 7 (centered at 648 nm, 858 nm, 470 nm, 555 nm, 1240 nm, 1640 nm, and 2130 nm, respectively). The product is an estimate of the surface spectral reflectance for each band as it would have been measured at ground level if there were no atmospheric scattering or absorption. The surface-reflectance product is the input for product generation for several land products: vegetation Indices (VIs), BRDF, thermal anomaly, snow/ice, and Fraction of Photosynthetically Active Radiation/Leaf Area Index (FPAR/LAI).

MODIS/Aqua大气校正地表反射率5分钟L2扫描带250米、500米、1公里NRT产品，简称MYD09，由MODIS Level 1B陆地波段1、2、3、4、5、6和7（分别以648纳米、858纳米、470纳米、555纳米、1240纳米、1640纳米和2130纳米为中心波长）计算得出。该产品是对每个波段地表光谱反射率的估计，假设在无大气散射或吸收的情况下，这些反射率将在地面水平上被测量。地表反射率产品是生成多种陆地产品（如植被指数（VIs）、双向反射分布函数（BRDF）、热异常、雪/冰以及光合有效辐射/叶面积指数（FPAR/LAI）的生成）的输入。
