HF Radar surface current velocity dataset in the Eastern Australia (2012-2023): version 1.0

This dataset contains the HF radar surface current velocity collected along the eastern Australian coast from 2012 to 2023. It includes data from two radar sites: Coff Harbour (COF, 153°9'E 30°18'S) and Newcastle (NEWC, 151°49'E 32°55'S). The spatial resolutions of the data are 1.5km upstream (COF radar) and 6km downstream (NEWC), and they cover an area approximately 150km from the coast. The dataset covers the period from 2012 to 2020 for the upstream radar (COF) and from 2018 to 2024 for the downstream radar (NEWC). The dataset was quality-checked and gap-filled by the variational approach (2dVar). Two-dimensional variables: Sea-surface current velocity in zonal (UCUR) and meridional (VCUR) directions.
