Under development

Under Development

  • 2-way coupling between ocean and atmosphere circulation models – put the O in COAMPS

  • Couple wave models with ocean and atmospheric circulation models

  • Automate flow of data and model results from one model to another – DIOPS for waves

  • Integrate sediment transport models with coastal circulation models

  • And I haven’t even talked about ice modeling!

Surface drift modeling

Surface Drift Modeling

  • Coupled operational models for wind, waves and 3D currents now exist, and we can now build (and assess!) an operational surface drift model.
