| Zusammenfassung |
| Different formulations of SEIK filter have been implemented and validated for NOAA sea
surface temperature (SST) data assimilation into BSH operational 5 km resolution circulation
model for the North and Baltic Seas. Initial model variance/covariance matrix has been
computed with given one year (10.2007 — 09.2008) of model integration. The SST data are
assimilated every 12(24) hours in order to improve model forecast for the sea surface
temperature. Salinity, sea surface high and velocity fields are also included in the model state
vector. As some independent information we have used temperature and salinity
profiles from a number of Marnet stations and sea level observations at tide gauges. |
