Sensitivity experiments to lateral open boundary conditions dataset used in the physical
component of the MyOcean Mediterranean Monitoring and Forecasting Centre (Med-MFC),
have been performed and the results are presented. The operational Mediterranean Forecasting
System (MFS) is based on the NEMO code and it is currently nested with monthly
climatological means computed from 10 years simulations of the Mercator-Ocean global system
at ¼ deg.
Two additional lateral open boundary condition datasets from the MERCATOR-OCEAN
Global Ocean forecasting System (GLO-MFC) have been considered: the first covers the period
from January 2007 to December 2012 and derives from a pre-operational global model
implementation; the second covers the period January 2013 – May 2014 and has been retrieved
from global products of the MyOcean catalogue. The daily products of the first dataset is
provided on native MERCATOR curvilinear grid, while the second daily operational dataset is
provided on regular grid according to the MyOcean operational procedure.
For each dataset a twin experiment has been performed using also the current MFS
operational set-up. Model results have been evaluated using ARGO floats and sea level data
from the Italian National Tide Gauge Network.
The results show a sensible improvement in the sea surface salinity after 1.5 years of
simulation, while differences in temperature and sea level are less evident.
