资源简介:
ASTER is an instrument on the Terra satellite. ASTER Global Emissivity Dataset (GED) is a global, 90-meter spatial resolution emissivity map of the Earths non-frozen land surfaces at different wavelengths in the thermal infrared spectrum. ASTER GED bands 13, 14, and Normalized Difference Vegetation Index (NDVI) are used in the surface temperature algorithm for Landsat 4-8 data.
高级星载热发射与反射辐射计(ASTER)是搭载于泰拉卫星(Terra)的对地观测有效载荷。ASTER全球发射率数据集(GED)是一套覆盖全球、空间分辨率为90米的热红外光谱不同波段下的地球非冻结陆地表面发射率分布图。ASTER GED的第13、14波段与归一化差分植被指数(Normalized Difference Vegetation Index,NDVI)被应用于陆地卫星(Landsat)4-8数据的地表温度反演算法当中。
