Recently the atmospheric pressure gradient forcing has been implemented in the oceanographic model used in the Mediterranean Forecasting System data assimilation scheme. Experiments show that there is an impact on how the temperature and salinity is updated in the assimilation when the ocean model is forced by the atmospheric pressure gradient. It is, however, necessary to perform longer data assimilation experiments to quantify the impact on the quality of the MFS analyses of the state of the Mediterranean Sea.
