In 2000, coastal currents off the coast of Norway were
measured and modelled during an experiment of the European Radar Ocean Sensing
(EuroROSE) project (funded by EU). The objective of EuroROSE was to develop a
radar based ocean monitoring system in support of safe navigation in port
approach areas and otherwise densely operated sea areas. Radar measured data
were assimilated into a fine gridded numerical model with the aim of
predicting, for a few hours, currents and waves. Maps and time series of
current velocity measured by the HF radar WERA (Wellen-Radar) are compared with
results of the numerical model. The model is capable of reproducing the spatial
and temporal variability of the measured currents for nowcasting. The
correlation between the measured current velocities and those predicted by the
model decreases from about 0.9 of the nowcast to 0.8 of the 2-h forecast and to
0.6 of the 6-h forecast.
