Professor Li’s research has focused on the theoretical and observational foundations of meteorological satellite remote sensing, with particular emphasis on radiative transfer modelling, atmospheric profile retrieval algorithms, and the calibration and validation of satellite-borne infrared and microwave sounders. Through international collaborative projects involving China’s meteorological satellite programme, NASA, NOAA, and the University of Wisconsin–Madison, his work has addressed the assimilation of satellite observations into numerical weather prediction models, hyperspectral infrared sounding techniques, and the development of next-generation geostationary meteorological satellite observation systems in China. He has authored numerous peer-reviewed publications in remote sensing and atmospheric science journals and has contributed to the development of satellite-based meteorological observation capabilities in China. Through sustained research, leadership of national satellite programmes, and international scientific collaboration, Professor Li has contributed to connecting advances in radiative transfer physics and satellite remote sensing with operational applications in weather forecasting, climate monitoring, and disaster early warning.
