| Abstract: | This study presents the upgrade of the Optimal
Interpolation scheme used in the basin scale assimilation
scheme of the Mediterranean Forecasting System. The modifications
include a daily analysis cycle, the assimilation of
ARGO float profiles, the implementation of the geostrophic
balance in the background error covariance matrix and the
initialisation of the analyses. A series of numerical experiments
showed that each modification had a positive impact
on the accuracy of the analyses: The daily cycle improved
the representation of the processes with the temporal variability
shorter than a week, the assimilation of ARGO floats
profiles significantly improved the salinity analyses quality,
the geostrophically balanced background error covariances
improved the accuracy of the surface elevation analyses, and the initialisation removed the barotropic adjustment in the forecast first time steps starting from the analysis. |
