MARCOORA Products

being added to SAROPS •  WeatherFlow wind monitoring stations •  Long Range HF radar surface currents •  Short-Term (24hr) Predictive System (STPS) surface currents based upon HF radar currents

WeatherFlow

Next Steps & Issues •  HF radar •  STPS •  WeatherFlow •  Canadian HF radars •  National HF servers •  Numerical models •  Dispersion / Uncertainty modeling

HF radar •  Issue with Null data values •  Verify daily file aggregation over UTC

rollover •  Currently on ASA Production EDS •  Needs to be moved to USCG EDS along

with STPS

STPS •  Short Term Predictive System

– Uses HF surface currents to predict next 24 hours of currents, tides plus persistence

•  Currently on ASA Staging EDS •  Aggregation issues w/STPS

– 24 hour forecasts – Aggregated with HF surface currents fields

•  Needs to be moved to ASA production EDS

WeatherFlow •  Issue with Time Windowing

– Not in sink with SAROPS data calls – Length of archiving

•  Currently deployed on ASA production EDS

Canadian HF radar •  Just coming on line •  Project funded by Canadian CG for

inclusion into CANSARP •  CGC looking into SAROPS as replacement

for CANSARP •  Add Canadian HF data be sent to US

national system?

Eastern Gulf of Maine HF radar

National HF servers •  NDBC, Scripps, Rutgers •  HF data, but where’s the forecasts? •  Coverage is expanding, for now •  One stop shopping! Sweet.

National HF Coverage

Numerical Models •  Year 2 and 3 of MARCOOS work to add

numerical models •  Focused on NY area •  Data assimilation of HF surface currents! •  Data assimilation of surface drifters !! •  To be added to the EDS

Dispersion Uncertainty modeling

•  SAROPS uses simple random flight model – High / Low values

•  Would like to improve random flight model in SAROPS

•  Would like to explore other models of dispersion for SAROPS

•  Would like to explore uncertainty determination of model outputs.
