Clear-sky retrieval of atmospheric temperature and water vapor using microwave and infrared hyperspectrometers Lei Liu et al. http://doi.org/10.17632/524hj3w6r8

Short summary

This study evaluates and compares a new microwave hyperspectrometer with an infrared hyperspectrometer for clear-sky temperature and water vapor retrievals. The analysis reveals that the information content of the infrared hyperspectrometer exceeds that of the microwave hyperspectrometer and provides higher vertical resolution in ground-based zenith measurements. Leveraging the ground–airborne synergy between the two instruments yielded optimal sounding results.
