Meeting in Chamonix, May 2014

To discuss:

• what's the point?
  • present a model comparison to the community
• what should be compared?
• who wants to be involved?
• what are the goals?
• time frame?

• "exact" ICs:
  • compare models with same/similar physics
• "general" ICs
  • compare models with different physics
• 1D & 2D plan-view (3D?)
• Other things which we may want to include in the far future:
  • ice flow
    • what flow models
  • groundwater flow
  • surface/englacial hydrology
  • ocean
  • etc

• Input fields:
  • bed and surface
  • melt forcing
  • ice flow speed
  • moulins
• Physical parameters:
  • how to set parameters in physically different models?
    • fitting: calibrate parameters to fit some (steady) state. Then predict some others?
      • what do we want to fit?
        • outflow
        • eff. pressure
        • measurable parameters vs full fitting
    • mathematical translation?

• what do we want to test/compare?
• how many ICs do we want?

Synthetic:

• box ice sheet margin (start with this only)
• flat valley glacier (+ overdeepening)
• mountain glacier (Hoffman et al 2013)
• Tide water glacier

Real:

• Russell/Leverett
• Gorner
• Arolla

• steady (start with this)
• diurnal
• seasonal
• seasonal + diurnal
• jokulhlaup
• processed met-data

How to compare the model outputs?

Metrics:

• effective pressure in a area
• flux
• storage

Others: lateral average, elevation bands, statistics

Drainage system morphology:

• channel spacing
• lateral variation in N

Technical:

• file formats: NetCDF

• who wants to participate?
  • Mauro, Tim, Ian, Christian, Basile, Matt, Gag
• time frame
  • hydro workshop: first week of October?
• Mauro makes a web-site
• publication
• name:
  • SHINT STORM
  • GHIP

• Tim Creyts
• Ian Hewitt
• Christian Schoof
• Basile de Fleurian
• Matt Hoffman
• Olivier Gagliardini
• Gwenn Flowers
• Jesse Johnson
