F1BM on the right. 
3.4 Salinity 
Unfortunately only few observations were available in die chosen calibration period, so 
only salinity at some Baltic stations has been analyzed. Generally the model captured the 
surface salinity quite well. Moreover, due to good initial conditions, the salinity below the 
halocline i.e. at depths greater than 60-80m, shows also a good agreement. At depths 
above die permanent halocline and below the surface like the bottom of all German Bal 
tic stations measurements show generally stronger fluctuations than die model does and 
the bias and die RMSD are also relatively high. This is most probably owed to a combina 
tion of the complicated batiiymetry of the Baltic Sea and die (probably too) coarse verti 
cal resolution of die applied model setups. As an example Fig. 10 shows the salinity time 
series at station Fehmam Belt.
