Physical Oceanography - In-situ and satellite data analysis. Characterization of salinity variability at global scale from ARGO profiler data and model outputs for SMOS data validation purpose: horizontal, temporal and vertical variability. Statistical methods for global mapping. Validation of SMOS brightness temperature images. Error analysis and post-calibration of polarimetric SMOS data : characterization of spatial biases in the antenna frame, temporal and latitudinal biases based on specific data selection strategies; RFI detection; Total electronic content inversion; Empirical forward model improvement : roughness contribution to emissivity, bistatic celestial signal reflection; Salinity inversion at L-band.
Past : surface waves, wind and air-sea momentum flux, altimeter backscatter. Characterization of wave growth impact on altimetric roughness and surfave wave statistics . Coastal hydrodynamical modelling.
