It is a great challenge to accurately monitor the atmosphere during climate change. Although sensors and technologies have been developed for basic meteorological variables such as temperatures and humidity, their measurements remain severely lacking or inaccurate in critical regions, such as the planetary boundary and the tropopause region.

The purpose of the project is to support the development of a microwave hyper-spectral remote sensor of the atmosphere, HiSRAMS, designed for the future generation of Earth observation satellites. The main objectives are to acquire collocated high-spectral resolution microwave and infrared atmospheric radiation spectra and verify the radiometric accuracy in the measurements, and to compare microwave hyperspectral to infrared hyperspectral in terms of accuracy and information contents of atmospheric temperature and humidity retrieval.
