Safer navigation in coastal areas with the aid of radar-measured surface currents
Heinz-Hermann Essen, Klaus-Werner Gurgel and Thomas Schlick

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.
