icepack - Icepack1.5.0

Icepack version 1.5.0 is being released with CICE6.6.0. This is a major release update from the Icepack1.4.1 release from May, 2024. The Icepack BGC has been significantly updated. The public Icepack interfaces have been refactored, and two public interfaces were renamed with backwards compatibility provided. . The floe size distribution conservation properties were improved, and the snow and ice enthalphy calculation was updated in the lateral melt process. Finally, an alternative congelation formulation following Plante et al. was added.

NOTE: This version is not backwards compatible with earlier versions of Icepack due to changes in public interfaces (see below for a detailed summary). In addition, all answers are changed.

Major Changes

• BGC update #497 (updates BGC physics consistent with E3SM, begins deprecation of skeletal-layer BGC, cleans up interfaces, updates bgc namelist defaults and settings in icepack_in and bgc tracer sizing in set_env files)

Bug fixes

• Fix conservation issues in the floe size distribution. Changes answers in FSD cases. #495
  • Use initial ice and snow volume values at the beginning of the lateral melt routine to update the snow and ice enthalpy as well other tracers for lateral melting. Changes answers in all cases.
  • Move the computation of vi0new_lat (lateral growth from FSD) outside of subroutine fsd_lateral_growth and check that the category new ice volume (vin0new) does not exceed the total vi0new.
  • Redefine floe_area_c to be precisely halfway between floe_area_l and floe_area_h.
• BGC update #497 fixes bug in subroutine snow_redist computation of hsn_new when nslyr=1
• Add a check and abort for negative values in the sqrt in computation of Tin in function calculate_Tin_from_qin. #502

Enhancements

• Update Icepack interfaces to remove arguments that are not needed, for minor physics changes, and as part of the BGC refactor. See below for more details. #497 #495 #502
• Alternative congelation formulation following Plante et al. 2024 #494
• Make dsnow and dsnown optional in icepack_step_therm1 #506
• Rename two public Icepack subroutines. Backward compatibility was maintained but we urge users to update their drivers to use the new names. #502
  • use icepack_therm_shared , only: icepack_init_thermo => icepack_init_salinity
  • use icepack_therm_shared , only: icepack_init_trcr => icepack_init_enthalpy
• Store static FSD information in Icepack rather than passing it through argument lists; remove fside #495
• Update timeseries script plot fonts and titles, add run_testoutput script #490
• Machine ports #496, #501, #502

Documentation

• Update version number to 1.5.0 #507
• Update documentation for adding a tracer and the tutorial #493
• Update comments associated with floeshape constant attribution and kice #502

icepack - Icepack1.4.0

Icepack version 1.4.0 is being released with CICE6.5.0. This is a major release update from the Icepack1.3.4 release from September, 2023.

Some of the interfaces have changed, some new parameters were added, the 5-band snicar shortwave feature was added, the frazil ice coupling was updated, and a bug was fixed lateral bottom melting term that doesn't impact science.

Major Changes

Add NO_SNICARHC to turn off large hardcoded 5-band data table during compilation to save compilation time.

  • Update icepack parameters, add hi_min, Tliquidus_max, snw_ssp_table, 'dEdd_snicar_ad' option to shortwave, 'constant' to tfrz_option
  • Update the Tf implementation to make values internally consistent. Remove hardcoded Tocnfrz in a couple places, add tfrz_option='constant' which sets Tf to Tocnfrz.

This release fixes a couple of minor bugs in the floeshape setting and in the convergence criteria in the atmo_boundary_layer method. In addition, some namelist variables were added and moved between namelist groups.

Major changes:

Bug fixes:

• Remove duplicate definition of floeshape and set it to 0.66. Prior versions had it set to 0.666 in fsd and 0.66 outside fsd. This changes answers but only affect the results of the fsd cases. #342

icepack - Icepack1.2.3

Icepack version 1.2.3 is being released with CICE6.1.3. This is a minor release update from the Icepack1.2.2 release in June, 2020. This release fixes a couple of minor bugs in the old aerosol scheme and in the snow melt term. It also revises the shortwave redistribution option and adds a few other features. Documentation was updated as well.

Major changes:

Bug fixes:

• Fix aerosol tracer bug #330. This fixes a bug in the old aerosol scheme (tr_aero). Some quantities were divided by aice and should not have been. This will changes answers for some configurations with tr_aero=.true.
• Fix snow melt bug #328. This fixes a bug in the thermodynamics. When the sea ice completely melts away, the final little bit of snow melt was not added to the melts array. This will probably change answers for most cases, but not science.

Enhancements:

• Update and Document C Preprocessor (CPP) flags. #329
• Add shortwave redistribution option including sw_redist, sw_frac, and sw_dtemp namelist. This could change answers, but proper namelist settings should recover bit-for-bit results. Users should review the new settings. Prior to this update, sw_redist was turned on automatically for (bl99) thermodynamics and turned off for mushy thermodynamics. By default, sw_redist is false (off) for all thermodynamics settings now. #326, #332
• Add fswthru as four components #320

icepack - Icepack1.2.0

Icepack version 1.2.0 is being released with CICE6.1.0. This release adds the joint thickness and floe size distribution (FSD) feature as well as other technical enhancements. Because of changes in several interface routines noted below, this version is NOT backwards compatible with prior versions. We continue to work toward a set of interfaces for Icepack that are flexible, extensible and easy to maintain, so that future Icepack upgrades minimize the amount of changes required in host models.

Major changes:

icepack - Icepack version 1.0.2

This minor update of version 1.0.0 is largely to establish a DOI number for the Icepack repository. We skipped releasing version 1.0.1 because the documentation move to readthedocs was incomplete in that edit.

Enhancements:

• Moved documentation to readthedocs #187

icepack - Icepack version 1.0.0

The CICE Consortium’s new sea ice column physics code includes all physical parameterizations from the CICE sea ice model that are limited to single grid-cell columns or Lagrangian elements, independent of the grid and other sea ice model infrastructure. Many aspects of the physics and biogeochemistry that were previously embedded in CICE version 5 now reside within Icepack, and new features have also been added. In addition to the column physics modules from CICE, this software package includes a stand-alone driver and automated testing using a comprehensive test suite.

Enhancements:

• Full vertical biogeochemistry code, including particulate iron, humic material, modal aerosols, proteins, stationary and mobile phases
• Biogeochemical feedback on sea ice physics through the shortwave formulation
• Optional inclusion of ice velocity in the calculation of wind stress
• Multiple options for column forcing, including CFS model output, Arctic and Antarctic physical and biogeochemical measurements, and an Arctic climatology
• A warning package that captures diagnostic and error information from within the column physics, for printing by the driver
• A comprehensive test suite of various configuration options for full code coverage
• Automated testing using Travis CI
• Automated test reporting organized by hash, version, machine and branch, for both the primary Consortium repository and user forks
• Online documentation
• A flexible, extensible, robust interface between the column physics modules and the driver

Bug fixes:

• limit exponential arguments to avoid underflows in shortwave, mechanical redistribution, brine height (PR #127 #132 #158 #169)
• Use vvel instead of uvel for y-component of atmosphere-ice stress with high-frequency option (PR #142)
• Use net shortwave sum instead of cosine of the zenith angle to limit shortwave calculation for low-/no-light conditions
• Correct roundoff errors in the delta-Eddington shortwave calculation
• Define interface temperature in the brine height parameterization
• Provide flexibility for tracking frazil ice salt/water in the ice or ocean model component
• When ponds are very thin, ignore them in the radiation calculation
• Ensure fractions of snow, ponds and bare ice sum to 1
• Wrap pond tracers in conditional blocks in mushy thermodynamics and form drag parameterization
• Miscellaneous bug fixes for biogeochemistry and brine height tracer (hbrine)
