| attribute | NC_GLOBAL | summary | String | Surface ocean velocities estimated from HF-Radar are representative of the upper 0.3 meters of the ocean. The main objective of near-real time processing is to produce the best product from available data at the time of processing. Radial velocity measurements are obtained from individual radar sites through the U.S. HF-Radar Network. Hourly radial data are processed by unweighted least squares on a 500m resolution grid of the U.S. West Coast to produce near real-time surface current maps. |
