Abstract: Atmospheric temperature and humidity profile is the key and basic meteorological parameter in the analysis of 
atmospheric thermal state, the study of atmospheric development and changes, severe weather warning, and numerical 
weather prediction. Retrieval algorithm of atmospheric temperature and humidity based on infrared spectra has 
been developed since 1960s, and can be divided into ground-based infrared retrieval algorithm and satellite-based 
infrared retrieval algorithm according to different observation positions. Basic types of retrieval algorithms 
of atmospheric temperature and humidity based on infrared spectra are summarized. The development 
of ground-based and satellite-based infrared detection methods for atmospheric temperature and humidity profile 
retrieval is introduced. Meanwhile, the retrieval method of atmospheric states combining ground-based with 
satellite-based infrared sounder is analyzed. Finally, the applications and development trend of atmospheric 
temperature and humidity profile retrieval method based on infrared spectra are briefly discussed.

Key words: infrared spectra, temperature and humidity profiles, retrieval, combining retrieval
