1-Land: Experimental campaign (Sodankylä, Finland) and satellite data analysis (CyGNSS, TDS1) to determine the geophysical information content of GNSS-R in wetlands (great uncertainty in climatic studies), contributory activity to a NASA project for 'Land Cover and Land Use (LCLUC) Research in Southeast Asia. '
2-Ocean: improvement of data retrievals through upgrades of the open source code 'wavpy', developed by the group (simulation/analysis); data analysis of the first GNSS-R synoptic receiver for precise altimetry designed to be embarked in drones (SPIR-UAV) and spatial data of the CyGNSS mission. Demonstration of the grazing angle altimetry from space using CyGNSS data. New spaceborne wind speed retrieval algorithms with CyGNSS. Demonstration of a new concept for direct measurement of sea currents, based on the Doppler effect of SoOP reflections.
3-Cryosphere: Campaigns and analysis of satellite data to understand the response of GNSS-R over sea ice (MOSAiC campaign), and on permafrost (Sodankylä, Finland). Processing of data from TDS-1 and CyGNSS satellites with the same purpose, which is a potential new ice thickness estimation technique.
4-Atmosphere: Maintenance, exploitation and dissemination of the ROHP-PAZ experiment on the PAZ satellite, demonstrator of the new GNSS PRO measurement concept developed in the group and representing the only sensor capable of simultaneously measuring the thermodynamic and precipitation structure of extreme phenomena. The experiment involves international agreements (NOAA, UCAR, JPL) for ROHP-PAZ data use in operational meteorology and research.
