The Mediterranean Forecasting System (MFS) is an integrated operational activity in the Mediterranean which combines observations, data assimilation and forecasting. Since September 2004 the MFS has deployed 23 ARGO floats in the Mediterranean. In the same period it started to use a new oceanographic model set-up based the 1/16th degree and 71 vertical layers ocean general circulation model combined with a multivariate optimal interpolation scheme. The system produces daily analysis of oceanographic parameters by assimilating satellite observations of sea surface temperature and sea level anomalies, and in situ observations of vertical profiles of temperature and salinity made by XBT and ARGO floats. The presentation will describe the MFS assimilation system and demonstrate the impact of the multivariate assimilation of satellite and in situ observations on the quality of MFS analyses and forecasts.
