摘要
为了对比研究针对Landsat 8数据的地表温度反演算法,选择南京市为研究区,采用Jiménez-Muoz等提出的SC和SW算法对地表温度进行反演,结果表明,SC算法比SW算法反演的地表温度平均高3.67 K.然后采用模拟数据法来验证两种算法的反演精度,结果表明,基于TIRS 10波段数据的SC算法平均反演误差在1K以内,与基于TIRS 10,11波段数据的SW算法相比结果更为可靠.
In order to compare algorithms to invert land surface temperature (LST) with Landsat 8 satellite data, the paper tries to invert LST through selecting Nanjing as the research area by use of SC and SW algorithms proposed by Jim6nez-Mufioz, et al. The results show that the LST inverted by SC algorithms is 3.67 K more than LST by SW algorithms on average. Then the pa- per uses the simulated data method to evaluate the accuracies of two algorithms. The results show that the average inversion tolerance of SC algorithm based on TIRS 10 band data is restrict- ed within 1 K. Compared with SW algorithm based on band 10, 11 data, SC is more reliable.
