对于定量热红外遥感的一些思考

SOME THINKING ON QUANTIATIVE THERMAL INFRARED REMOTE SENSING

作者根据在热红外遥感工作中的长期实践经验，介绍了热红外遥感的现状，特别指出了定量反演地表温度的难点———地物比辐射率的测定和区域范围内的比辐射率估算。文中提出了定量热红外遥感研究中常见的一些问题。最后，讨论了定量热红外遥感的未来发展趋势和目前现实工作的对策，旨在抛砖引玉，以求得热红外定量遥感的发展。

In terms of the practice of author for long time, development and situation in thermal infrared remote sensing research field were introduced in the paper. Particulary, major difficult in quantitatively investing of ground surface temperature, measurement of emissivity and its estimation in regional scale, was presented. Some problems in the quantitative application of thermal infrared remote sensing for some researchers were also pointed out. Finally, developing tendency in future and countermaeasure for recent works were discussed. The goal in the paper is “to cast brick and to attract jade' in order to promote the development in quantitative thermal infrared remote sensing.
