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 1km resolution grid of the U.S. East and Gulf Coast to produce hourly near real-time surface current maps. The month average is computed from all available hourly near real-time surface current maps for the given month. instrument: Earth Remote Sensing Instruments, Active Remote Sensing, Profilers/Sounders, Radar Sounders, Doppler RADAR keywords: Earth Science, Oceans, Sea Surface, Coastal Processes, Marine Environment Monitoring, Ocean Circulation, Ocean Currents, Wind-Driven Circulation, Atlantic Ocean, North Atlantic Ocean, Gulf of Mexico geospatial_lat_min: 21.7 geospatial_lat_max: 46.49442 geospatial_lon_min: -97.88385 geospatial_lon_max: -57.192493 processing_level: Near real-time dataset with automated data acquisition and processing quality control history: 2024-03-13T00:25:59Z hfrnet ltaSaveNetcdf: Writing values to file references: Terrill, E. et al., 2006.
