Scatterometer Winds Use in Météo-France
An intense activity is underway around the scatterometer winds, no less than 6 instruments are flying currently around the earth, which is an unedited configuration. The operational numerical weather prediction model of Météo-France assimilates the ASCAT winds from MetOp-A and MetOp-B satellites (EUMETSAT) for many years. ScatSat-1 (ISRO) was successfully added during the last upgrade of the model in July 2019. ASCAT from MetOp-C is currently evaluated by the Operations and should become operational by January 2020. The evaluation of the last two new ones, HY-2B (NSOAS) and CFOSAT (CNSA/CNES), is ongoing with first assimilation experiments in a research context. At the same time, improvements in the assimilation of all these data is sought. The work and the results around this activity will be presented.
