  8. from Hawaii from Woods Hole Generic visualization tools via standards: IDV

  9. IDV: Hurricane Katrina

  10. IDV Demo

  11. Matlab/NetCDF

  12. Matlab and CF • Matlab can access Java routines! • Could we do away with machine-dependent “mex” interface by using NetCDF-Java? Maybe. Not a one-to-one correspondence between NetCDF-Java & C/Fortran Interface. • SNCTOOLS reading tools (e.g. nc_varget, nc_attget) now work with Java, but writing still requires mexnc.

  13. RSLICE can run on Java! …and so could any other read-only viz or analysis tool. ROMS_GUI?

  14. Matlab/NetCDF Question: Can we use NetCDF Java to avoid re-coding CF-logic into Matlab routines? Answer: Yes!

  15. CFtime.m (traditional)

  16. CFtime.m (with NetCDF Java)

  19. The Way Forward • Work with CF Conventions Group, IOOS MAST, and ESMF Developers to ensure that developing CF Standards meet ocean community (including ROMS) needs • Build a CF toolbox for Matlab, using NetCDF-Java • Build a CF toolbox for Python, using CF-Lib (C) • Build and support analysis and visualization tools that work with CF standards (e.g. IDV) • Listen to the Community! • Standardize the Interface!

  20. NRL SSC Role in the Battlespace Environments Institute Rick Allard, Tim Campbell • Build ESMF interfaces within existing scalable ocean models (HYCOM, NCOM, SWAN and ADCIRC) • Provide the necessary components for applications with atmospheric, ocean, ice, and riverine models. • Develop coupled applications to support operational Navy: • HYCOM-CICE (ocean, ice) • SWAN-ADCIRC (wave, circulation) • ADCIRC-WASH123D (circulation, riverine, watershed) • COAMPS-NCOM (atmosphere, ocean)

  21. Simple Matlab Access nc=netcdf(‘fem.nc’); lon=nc{‘lon’}(:); lat=nc{‘lat’}(:); ele=nc{‘ele’}(:); salt=nc{‘salt’}(1,1,:); trisurf(ele,lon,lat,salt) [t,b,jday,u]=CFtime(nc,’time’) title([‘Salt ‘,datestr(jday(1))])

  22. CFtime.m (with API)

  23. ERDC’s XMDF 104 pages

  24. UnstructuredAdaptive GridImperial College Ocean Model (ICOM) Matthew Piggott (Imperial College, UK)

  25. FVCOM using LLNL’s “VisIt”Free software based on VTK w/Java,C++,Python interfaces Chen & Cowles, UMASSD

  26. Unstructured Mesh Priorities • CF Conventions (define and adopt) • CF APIs (C in addition to Java) • CF Reference Applications (e.g. IDV, CDAT, VisIt module)

  27. New ESMF-Based ProgramsFunding for Science, Adoption, and Core Development

  28. Origins of the CSTM • “A better understanding is needed of the basic physics that control sedimentary processes such as bottom roughness, aggregation or flocculation and disaggregation, erosion and deposition, and bed consolidation” • “Wide acceptance of a community sediment transport model would make an effective tool for scientific research. …no existing model has the features that would allow wide access and acceptance by the community: freely available code; state-of-the-art hydrodynamic and sediment algorithms with modern, modular coding; comprehensive documentation; and demonstrated performance on a suite of community defined test cases.” • “Coordination of the community modeling effort should be by an impartial organization with long-term stability”

  29. Community Sediment Transport Model (CSTM)

  30. CSTM Project Contributions • Suspended and bed load sediment transport • Multiple sediment classes • Bed framework & stratigraphy • New wave/current bottom boundary layer • Monotonic advection • Umlauf & Burchard GLS mixing • Test cases • Wetting/drying • Nearshore processes
