The Tasman International Geospace Environment Radar systems (TIGER) located in Tasmania and New Zealand are High Frequency (HF) Over-The-Horizon Radar (OTHR) systems and represent Australia’s contribution to the Super Dual Auroral Radar Network (SuperDARN). SuperDARN is a network of more than 20 HF radars located at mid-high latitudes with fields of view covering the polar regions for the study of ionospheric physics. The TIGER systems have overlapping fields of view that cover much of the Southern Ocean in the Australian sector. The development and operation of TIGER has been led by La Trobe University. The BoM-IPS has and continues to support their development and operation. Previous studies have shown that HF sky-wave radars are capable of determining dominant wind-wave direction, a proxy for surface wind direction, and line-of-sight velocities (towards or away from the radar) of ocean surface currents using the first-order Bragg peaks of backscattered ocean echoes. They have also shown that significant wave heights and mean wave periods can be estimated using the second-order Bragg peaks of backscattered ocean echoes. Whilst this kind of data can be obtained using satellites, ground-based radars have the advantage of being able to provide continuous coverage in the same geographical region of interest. For this project, estimates of dominant wind-wave directions, ocean surface currents, significant wave heights, and mean wave periods were obtained with the TIGER Bruny Island and Unwin systems.
