NOAA-AOML/UM-RSMAS Ocean Modeling and OSSE Center (OMOC)

The Ocean Modeling and Observing System Simulation Experiments Center (OMOC) is a joint center between UM/RSMAS and NOAA/AOML. Activities at UM are carried out by OCE and CIMAS scientists and are focused on the design, optimization, and evaluation of observing systems, especially related to the improvements of ocean forecasts. These forecasts cover a broad range of applications, such prediction of the transport and dispersion of oil and marine debris and hurricane prediction (improving the oceanic component of coupled hurricane models). The Center has developed a prototype system for ocean OSSEs (Observing System Simulation Experiments) for the North Atlantic Ocean and the Gulf of Mexico, with plans to expand on the global scale and with fully relocatable capabilities. The OSSE system methodology incorporates both modeling and observational techniques and analyses, including data assimilation and data based model evaluation.

Key Goals:

Research Projects:

  • Develop, evaluate, and validate a prototype ocean OSSE (Observing System Simulation Experiment) relocatable system
  • Use OSEs (Observing System Experiments) and OSSEs (both regional and basin-wide) to improve the quality of ocean analysis and forecasts for a broad range of applications:

    • Hurricane intensity prediction using coupled hurricane forecast models
    • Predicting the transport and dispersion of oil and marine debris
    • Monitoring and forecasting ocean climate variability
  • Communicate results of observing system impact studies to key stakeholders, such as:
    • Ocean and weather forecast centers
    • Ocean observing system programs
