Solver BasalMelt3D

General Information

• Solver Fortran File: BasalMelt3D.F90

• Solver/User Function Name: BasalMelt3D

• Required Output Variable(s): BasalMeltRate

• Required Input Variable(s):

  • Grounded mask (GroundedMask Variable = String...) - this will default to 'GroundedMask' if not specified

• Optional Output Variable(s):

  • None

• Optional Input Variable(s):

  • None

• Solver Keywords:

  • Basal Melt Stats File = String... (The path to write a file containing some stats to)

  • Basal Melt Mode = String... (can be 'seasonal' or 'off'. The latter is fairly self-explanatory; the former requires the following additional options:)

  • Basal Melt Summer Rate = Real... (The rate to apply basal melt at in summer)

  • Basal Melt Winter Rate = Real... (The rate to apply basal melt at in winter)

  • Basal Melt Summer Start = Real... (The time in the simulation to begin using summer melt rates (expressed as a number between 0 and 1))

  • Basal Melt Summer Stop = Real... (The time in the simulation to stop using summer melt rates (expressed as a number between 0 and 1))

General Description

This is a very simple solver written by Joe Todd that applies a specified basal melt rate to any ungrounded parts of the glacier base. This solver is part of the coupled calving-GlaDS-plumes suite described in this document. It may require additional work to be used outside of this context.

Known Bugs and Limitations

None
