多源遥感数据的温度反演算法与分析

Temperature retrieval algalgorithm based on multi-source remote sensing data

该文使用Artis&Camahan的辐射校正温度反演法,通过地表比辐射率和亮温反演结果的综合计算进行温度反演,最后对反演结果进行了精度验证,证明了该算法可以合理的反演出城市地表温度,得出该温度反演方法的有效性。

In this study,radiometric calibration algorithm proposed by Artis & Camahan was used,and the temperature retrieval was calculated by land emissivity and result of bright temperature inversion,which could reduce the complexity of taking atmosphere into account. At last,the precision testing about the retrieval result was carried out,which proved that this algorithm could reasonably reflect the urban surface temperature,and the retrieval algorithm was validity.
