New Features in CICE 5.0

physics

  • A method for prognosing sea ice salinity, including improved snow-ice formation
  • Two new explicit melt pond parameterizations (topo and level-ice)
  • Sea ice biogeochemistry
  • Elastic-Anisotropic-Plastic rheology
  • Improved parameterization of form drag
  • The "revised EVP" under-damping approach
  • Gracefully handles the case when an internal layer melts completely

infrastructure

  • Ice and snow enthalpy defined as tracers
  • Gregorian calendar with leap years
  • Reduced memory and floating-point operations for tracer calculations
  • Restarts in binary, netCDF or PIO formats
  • CPP options for categories, layers and tracers
  • Read/write variables on the extended grid, including ghost (halo) cells

efficiency

  • Parallelism option via OpenMP threads
  • Improved parallel efficiency through halo masks and new block distributions
  • Parallel I/O option via the PIO library

miscellaneous

  • New history variables for melt ponds, ridging diagnostics, biogeochemistry and more
  • Corrected bugs, particularly for nonstandard configurations.
