THz波的频段范围（0．1-10 THz）及其特性使THz波具有较高的空间分辨率及大气参数灵敏性，同时THz辐射在地球辐射平衡中的重要作用决定了其在大气探测领域有重大的研究价值和广阔的应用前景。介绍了THz技术在大气探测领域的应用现状，重点分析介绍了THz波遥感探测大气水汽廓线、温度廓线、卷云的微物理参数及大气微量气体成分的原理、特性及存在的问题，最后对THz波大气探测技术的研究提出几点建议和展望，并指出了当前THz波大气探测技术的研究前沿和研究热点。

The range of THz frequency （0.1-10 THz） and its characteristics enable THz wave to have a higher spatial resolution and atmospheric parameter sensitivity. Moreover, the important role of THz radiation playing in the earth＇s radiation balance determines that THz radiation has great research value and broad application prospects in the atmospheric sounding field. The research progress of THz technology application in the atmospheric sounding field was presented, as well as the analysis of the principles, characteristics and existing problems of THz wave remote sensing for the atmospheric humidity profiles, atmospheric temperature profiles, cirrus clouds microphysical parameters and atmospheric trace gas composition. In the last section, several suggestions were put forward for THz wave atmospheric sounding technology research and the frontier and hotspot issues of the research were pointed out.
