Description

Icepack version 1.5.1 is being released with CICE6.6.1. This is a minor release update from the Icepack1.5.0 release from November, 2024. This release features two major updates, addition of MDF/MOSAiC forcing and a new sea-level pond scheme. This release also includes several bug fixes including a fix for the pond density and area fraction, a fix in the implementation of calc_tsfc=.false., and a fix for negative silicates in ice BGC. This release also includes the ability to use a semi-implicit thermodynamic coupling option, enforce mass and energy conservation for sublimation and deposition, and enable photosynthetic radiation as needed for NASA/GEOS coupling.

Major Changes

  • #500 Add MDF/Mosaic forcing options. Add several new icepack namelist including hi_init_slab, hsno_init_slab, hbar_init_itd, hsno_init_itd, sst_init, sss_fixed, qdp_fixed, hmix_fixed, and precalc_forc. Several migrate model defaults to namelist while precalc_forc modifies the forcing methods.
  • #515, #530 Add a new, sea-level pond scheme

Bug fixes

  • #504 Use freshwater density for ponds and correct pond area fractions. Changes answers for mushy physics with level-ice or topo melt ponds.
  • #513 Fix set_sfcflux argument order, which caused errors for models using calc_tsfc=.false.
  • #519 Fix negative silicate in ice BGC.

Enhancements

  • #509 Update Permutter port
  • #510 Update derecho gnu, add code coverage capability via lcov
  • #521 Complete deprecation of zsalinity
  • #523 Update set_version_number.csh to include automatic updates to the zenodo file, .zenodo.json.
  • #518 #526 Add a semi-implicit thermodynamic coupling option, enforce mass and energy conservation for sublimation and deposition, and enable photosynthetic radiation, as needed for the GEOS model.
  • #529 Move snow metamorphosis tuning parameters to namelist

Documentation

  • #514, #522, #524 Update Copyright, Distribution Policy, and License
  • #524 Update version to Icepack1.5.1
  • #525 Rename attribute in history output for proleptic gregorian calendars
  • #531 Update zenodo author list
