【摘要】 目前利用ASTER数据反演陆面温度的算法可划分为3类:ASTER TES(Temperature/Emissivi-ty Separation)算法,多通道算法,辐射传输算法。对上述3类方法进行了分析比较,提出了今后工作中要:实现遥感的综合反演、地表发射率的精确获取以及反演实用价值更大的组分温度的努力方向。更多还原

【Abstract】 At present the algorithms of retrieving land surface temperature(LST) by using ASTER data can be divided into three kinds: ASTER TES algorithm,Multi-channel algorithm and radiative transmission algorithm.Comparing them with each other,the authors pointed out the direction for the future work: realizing the integrative inversion in remote sensing,getting more accurate emissivity and retrieving component temperature with more applied value.更多还原
