Interactions entre poussières désertiques et convection profonde en Afrique de l'Ouest : Observations et modélisation à échelle convective

Autor: Kocha, Cécile

Dans un contexte de réchauffement climatique, la région d'Afrique de l'Ouest, où les sécherresses sont dévastatrices pour les populations, montre les plus fortes incertitudes sur l'évolution des précipitations. C'est aussi la première source

Analysis of the Sentinel-6A Michael Freilich L2P-L3 Sea Level Anomaly SAR-LRM bias correction

Autor: Kocha, Cécile, Pujol, Marie-Isabelle, Prandi, Pierre, Cadier, Emeline, Philipps, Sabine, Dibarboure, Gérald, Maréchal, Christophe, Jouan, Christophe

A bias correction (inter_mission_bias) is computed and applied to L2P Sea Level Anomaly to insure the continuity between Jason-3 and Sentinel-6A MF missions. For Sentinel-6A MF a technical note details the model implemented and its impacts over sea l
