S41 Ecological Forecasting: Progress, Challenges and Prospects


Outline

  • Southeastern Universities Research Assn (SURA)

  • Motivation for the Testbed: Improving prediction of environmental processes

  • Design of this Testbed

  • Year 1 Products

  • Future work


SURA’s Mission:To advance nuclear physics, information technology, and facilitate better understanding of coastal and environmental phenomena that impact our lives.

  • Year 1 products

  • Future work


Improving Forecasts of Coastal Environmental Processes

  • Factors:

    • open boundary conditions,

    • surface and river forcing conditions,

    • enhanced physics,

    • adjustable parameters,

    • data assimilation, numerics, amount of data assimilated,

    • skill of modelers(!),

    • vertical and horizontal resolution,

    • coupling to wave and met models.

  • “Which model is better?” is not the right question.

    • What factors in the simulation resulted in a better solution?

    • How much better?

    • At what cost?


Defining Improvement

  • To measure improvement for environmental processes, we need to define skill metrics for specific environmental processes and often for specific region:

  • Inundation ✔

  • Hypoxia ✔

  • Search and rescue

  • Deep oil spills

  • Navigation

  • Harmful algal blooms

  • Diver operations

  • Alternative energy citing

  • Beach erosion

  • Regional impact of climate change

  • -- ALL REQUIRE DIFFERENT SKILL METRICS!

  • Operational centers will directly benefit from the community’s help in this process – too broad for NOAA and NAVY!


  • A Common Cyberinfrastructure for Model Data

    The ocean community needs a common cyberinfrastructure to access, analyze and display data from the different models: each model community currently has their own standards and toolsets.

    A Testbed Framework for Coastal Ocean Models

    • Build a common infrastructure to enable access, analysis and visualization of all coastal ocean model data produced by NOAA, NAVY and IOOS

    • Develop skill metrics and assess models in three different regions and dynamical regimes, to ensure a robust and powerful infrastructure

    • Identify factors that could be transitioned to operations

    • Build stronger relationships between academia and operational centers through collaboration
