  1. Optimal Coastal Siting of HF Ocean Surface Radars for Larger Scale Ocean Dynamics Eric Schulz BMRC

  2. Rational • HF Ocean Surface Radars • Program of research

  3. Rational • Bureau involvement in Australian Integrated Ocean Observing System (AusIOOS) • HF Radars will be a part of AusIOOS • Site selection for HF Radar installations • Scientific input into site selection • Optimal data assimilation for modeling meso-scale ocean dynamics • Develop a tool to provide this

  4. HF Ocean Surface Radar CODAR receive antenna Currents from Rutgers

  5. Meso-scale dynamics around Australia

  6. The Question “Is there an optimal coastal location for observing the East Australian Current using a HF ocean surface radar, which will yield the largest improvement in model forecast skill of meso-scale eddies in the Tasman Sea?”

  7. East Australian Current and the Tasman Front

  8. Program of Research • Use Peter Oke’s Array design method to rank the best coastal locations for a single radar installation for determining meso-scale eddies in the Tasman • Surface current datasets • synTS: derived from climatology, satellite (altimetry & sst) and tide gauges • BRANII: BLUElink ReANalysis II, (ocean model) • Collect observations • Observations of EAC from HF radar (IMOS with UNSW) on the northern NSW coast 6-12 month deployment • Observations in the Tasman Front from a 5 year program of drifter deployments • Assimilation impact study • Use the BLUElink ocean model and • Observations • Compare assimilation impact study and array design results to validate the array design methodology
