Classic example of a CODAR station (coastal ocean dynamics applications radar). land-based, High Frequency (HF) radar. It was developed between 1973 and 1983 at NOAA’s Wave Propagation Laboratory in Boulder, Colorado. CODAR is a noninvasive system that permits to measure and map near-surface ocean currents in coastal waters. It is transportable and offers output ocean current maps on site in near real time. Moreover, using CODAR it is possible to measure waves heights and it provides an indirect estimate of local wind direction.
