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 ...
