My research mainly addresses the determination of the state of the atmosphere using ground-based and spaceborn remote sensing, both active and passive. Which measurement instruments can be usefully combined to observe a height profile of the entire troposphere, especially during cloud cover and precipitation? How could we use such measurements to parameterize precipitation evaporation, for example?

A novel synergistic retrieval approach to enable tropospheric temperature and humidity profiling under all weather conditions for an improved quantification of evaporation rates
