Comparison of drifting buoy velocities to HF radar radial velocities from the Ocean Networks Canada Strait of Georgia 25 MHz CODAR array [electronic resource] / By Mark Halverson, Jim Gower, Rich Pawlowicz. Sidney, B.C. : Fisheries and Oceans Canada, 2018. vi, 38 p. : charts (mostly col.), col. ill., maps (mostly col.)

"In August 2012, Ocean Networks Canada installed the second of two high frequency (HF) oceanographic radar systems in the Strait of Georgia to measure surface currents in and around the Fraser River plume area. These systems are used, in conjunction with software provided by the vendor, to generate maps of surface currents over a rectangular grid with a nominal resolution of 1 km at hourly intervals. As with any measurement, it is important to quantify the accuracy and precision of the HF radar current vectors. The vendor provides two quality metrics for this purpose. While helpful, it is necessary to compare the data to independent velocity measurement to determine whether any bias exists, and to check if the temporal and spatial quality are reasonable. In this data report we quantify the accuracy by analyzing drifter trajectories from a series of deployments that took place in the HF radar footprint. Surface drifters of two different designs were released, and their velocities were compared with those from the radar system”--Introd., p. 1.
