This page is a reduction of the/wiki/spaces/OCNICE/pages/30442728.
Each section (ocean, sea-ice, land-ice, coastal, coupler) get 15 minutes.
Goal of each 15 minute segment is:
- to ID the most important v2 feature(s)
- ID who is willing take the lead in pulling together a design document for feature(s)
ocean (Mark Petersen)
- performance
- Change number of layers to 64 or 128 for vector performance
- Always loop vertically to nVertLevels, or multiples of 8, with a mask ("Strip-mining")
- reduce excessive diagnostics computations, other items, see: /wiki/spaces/OCNICE/pages/82673686
- analysis
- Continued work on analysis members and MPAS Analysis
- smooth automated implementation in ACME, working at high resolution.
- non-Boussinseq / TEOS-10
- needed for steric SLR
- expected for next generation ocean models
- wetting-drying / massless layers
- needed for ocean / land-ice coupling, moving grounding line
- needed for coastal inundation
- high-order pressure gradient
- mitigates errors associated with strongly sloped layer interfaces
- quasi-Lagrangian vertical coordinate (regridding/remapping, hybrid vertical coordinates)
- exploits a capability built into MPAS-Ocean
- should improve representation / preservation of water masses
- super-cycling of tracer transport
- needed to make BGC more computationally tractable
- Mesoscale eddy closure
- funded by SciDAC3, in code base, needed to be validated in global configurations
- thin-wall approach for bottom bathymetry
- a great idea that we never have time to implement
- improved vertical turbulence scheme
- needed to get beyond KPP
- prognostic SW penetration model
- needed to improve ocean boundary layer representation
sea-ice (Adrian Turner)
- Improved snow model
- Icebergs
- Unified ridging and form drag
- Improved radiation extinction in snow (SNCR)
- MPAS-seaIce buoy simulator
- Improve salinity coupling btw ocean and sea ice
- Remaining sea ice metrics for coupled simulations
- Performance enhancements? - concurrent halo exchanges, equatorial grid culling in coupler
land-ice (Stephen Price)
- Improved calving
- spin up initialization
- Sub-glacial hydrology and basal processes
- Spatially-temporally varying sea-level forcing at land ice front
coupler (Jeremy Fyke (Unlicensed))
- Couple icebergs from land ice to sea ice via coupler
- time-variable footprint of land / ocean / sea-ice
- Self-attraction for regional SLR
coastal ocean / coastal BGC (Phillip Wolfram (Unlicensed))
- Tides
- needed for estuary modeling project
- variable time step
- would allow two-way coupling of open to coastal system models
- Surface wave model
- needed for inundation modeling
- needed for improved ocean boundary layer modeling
- Coastal BGC - Coupled river-estuary-coastal ocean reaction eqs.
- includes inorganic carbon chemistry
- extending BGC into the coastal ocean system
- Sediment transport
- needed for the evolution of the coastline and BGC processes
