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 near real-time surface current maps. 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, Tides, Tidal Currents, 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: 2020-06-28T01:19:35Z hfrnet rtvMergeData: Saving 1142 new solutions 2020-06-28T01:49:27Z hfrnet rtvMergeData: Saving 1326 solutions; 184 new or updated, 1142 unmodified from previous run(s) 2020-06-28T02:19:29Z hfrnet rtvMergeData: Saving 2729 solutions; 1403 new or updated, 1326 unmodified from previous run(s) 2020-06-28T13:19:48Z hfrnet rtvMergeData: Saving 2846 solutions; 117 new or updated, 2729 unmodified from previous run(s) 2020-06-28T13:19:51Z hfrnet rtvSaveNetcdf: Removed 784 solutions exceeding HDOP threshold of 1.25 references: Terrill, E. et al., 2006.
