| 摘 要： | 在进行一定区域地表温度时间序列的研究中,常遇到由于天气原因造成的温度数据缺失问题,针对这一突出问题,在分析土壤发射率数据库的基础上,提出了一种裸露地表晴空时段热红外、微波亮温数据与非晴空时段微波亮温数据相结合来获取时间序列中缺失的地表温度数据的算法.此算法不仅解决了被动微波进行地表温度反演过程中下垫面发射率难以确定的问...

| Abstract: | In the research of the land surface temperature time series,the critical problem is the miss of partial temperature data due to bad weather.Therefore,a novel method based on the analysis of soil emissivity database was put forward.The core of the method was to reconstruct bare soil temperature time series by means of combining thermal infrared and passive microwave remote sensing technology.It conquered the difficulty of determining the land microwave emissivity in the process of land surface temperature in... |
