Jason-3 data assimilated operationally in Météo France model

Category: News of the Jason-3 mission

Assimilation of Jason-3 Significant Wave Height into an operational Numerical Operational Prediction (NWP) system at Météo France.

Altimeters can measure sea surface height first and foremost the waves height, which is of prime importance to marine weather forecasters in terms of maritime safety. Since the run of 18:00 (UTC) on 6 october 2016, the operational wave model MFWAM at Météo-France assimilated operationally the Jason-3 wave data. The map below shows a snapshot of significant wave height (SWH) in meters capturing the high waves generated by the tropical storms NICOLE and MATTHEW. The SWH values are superimposed over the map along the Jason-3 ground tracks. By assilimilating into wave models, Jason-3 data improves the wave forecast.
