BEI Goals (cont.)

• Support battlefield decisions, improve
  interoperability, reduce operating costs,
  streamline the transition of cutting-edge
  environmental technologies from research into DoD
  operations.

5
BEI Strategy

• Use the Earth System Modeling Framework (ESMF) as
  an enabling technology to develop the
  whole-earth system.
• Bring in DoD as a partner to the ESMF.
  Transition non-DoD ESMF applications to DoD.
• Foster wider collaborations between DoD, multiple
  government agencies, academia and industry.

• BEI-02 Coupled Ocean-Atmosphere
• BEI-03 Space Weather Modeling System
• BEI-04 Coupled Watershed-Nearshore

BEI-01 Coupled Ocean-Ice

• Develop coupled HYCOM-CICE application
• ESMF-based HYCOM developed by NRL-SSC
• ESMF-based CICE developed by LANL
• All coupling by NRL-SSC
• Alpha/Beta test in 3Q/4Q FY06
• CICE is BEIs first non-DoD application
• Expect HYCOM-CICE to be in routine use at NRL-SSC
  during FY06
• Initially for Arctic-only domain
• Then for fully global domain
• ESMF-based global HYCOM-CICE expected to be
  transitioned to NAVO (OpTest) in FY07

BEI-02 Coupled Ocean-Atmosphere

• Develop ESMF based coupled ocean-atmosphere
  mesoscale prediction system (COAMPS)
• NRL Coastal Ocean Model (NCOM)
• ESMF version developed at NRL-SSC
• NRL COAMPS Atmospheric model
• ESMF version developed at NRL-MRY
• ESMF based coupler developed jointly by NRL-SSC
  and NRL-MRY
• Goals
• Include two-way coupling in COAMPS w/ESMF
• Allow for other models (e.g., HYCOM, WRF)
• Use WRF infrastructure to allow for other
  physics, standard I/O
• Alpha (one-way coupled) and Beta (two-way
  coupled) tests in FY06/07
• ESMF based two-way coupled system will be
  operational at Mission Support Center, San Diego

BEI-02 Motivation

• COAMPS one-way coupling tests have demonstrated
• Hi-res atmospheric fields improve ocean
  prediction
• Ocean model can be used as an atmospheric model
  metric
• Importance of native grid, unfiltered fields
• Importance of atmospheric data assimilation and
  high-resolution grids
• Encouraging results from prototype two-way
  coupling
• Improved atmosphere and ocean boundary layer
  predictions
• Successful simulation of hurricane-induced SST
  cooling
• ESMF based COAMPS will be more flexible
• Enhance development of more advanced models of
  the air-sea interface
• Enable coupling with other ESMF components (ocean
  wave, hydrological, etc.) in the future

11
BEI-02 Prototype Two-Way Coupling

• COAMPS one-way coupling tests have demonstrated
• Hi-res atmospheric fields improve ocean
  prediction
• Ocean model can be used as an atmospheric model
  metric
• Importance of native grid, unfiltered fields
• Importance of atmospheric data assimilation and
  high-resolution grids
• Encouraging results from prototype two-way
  coupling
• Improved atmosphere and ocean boundary layer
  predictions
• Successful simulation of hurricane-induced SST
  cooling

12
BEI-03 Space Weather Modeling System

• The sun emits electromagnetic energy and
  particles that interact with the earth. These
  emissions and interactions are called space
  weather
• Space weather impacts electronics devices and
  electromagnetic based communication
• Non-Solar Events Satellite communication
  interference, GPS navigation errors, surveillance
  errors
• Solar Flare Events Radio blackout, satellite
  communication interference, satellite damage,
  orbit changes, geomagnetic storms

13
BEI-03 Modeling Goals

• Couple ESMF versions of Hakamada-Akasofu-Fry
  (HAF) kinematic solar wind model and Global
  Assimilation of Ionospheric Measurements (GAIM)
  models
• Provide DoD with the ability to extend the
  forecast lead time of the arrival of a shock in
  the solar wind created by a Coronal Mass Ejection
  at the sun from 1 hour to 1-3 days.
• HAF predicts solar wind conditions (speed,
  density and magnetic field) at the Earth based
  upon observations of the Sun.
• GAIM provides a global ionospheric specification
  and forecast of electron density from 90km to
  1600km with a 15-minute cadence.

14
BEI-03 Prototype Success

• Prototype HAF-GAIM system developed that clearly
  establishes the motivation for coupling
• The coupled solution (right) was able to
  accurately predict an ionospheric event over
  southern Greenland and northern Canada while the
  stand alone, climatologically-based GAIM failed
  to do so.

15
BEI-03 Plans

• Scalable versions of HAF and GAIM FY06
• ESMF based coupled HAF-GAIM application FY07
• Operational ESMF based coupled HAF-GAIM at AFWA

  flow, and contaminant and sediment transport in
  WAterSHed systems

  and Estuaries (ADCIRC)

  dimensions

BEI-04 Coupling Issues Plans

• Initial coupling will be single shared boundary
  at coast
• ADCIRC provides water-levels to WASH123D
• WASH123D provides fluxes to ADCIRC
• ESMF support for unstructured grids currently
  under development
• Incorporate ESMF-ADCIRC into Community
  Sediment-Transport Model
