CICE6.4.1 updates CICE6.4.0 from August, 2022 and includes Icepack1.3.3. This release provides several minor upgrades to the recently released C-grid option. It has several bug fixes including in dEdd scheme affecting modal aerosols and the snow grain implementation. It has updated the VP dynamics option to improve robustness and reproducibility. It moved the evp dynamics deformation calculation to the end of the subcycling loop. It adds new features such as the saltflux_option. Testing and scripts have been updated including addition of a new variable spacing rectangular box option. This version deprecates the zsalinity option. Please contact the CICE Consortium with any concerns regarding deprecated code. We will consider keeping it. Important NOTES The C-grid implementation is available. However validation is ongoing. Some noise is generated in the solution when incremental remapping advection is used with the C-grid. One solution seems to be to use the upwind advection scheme instead which is more ...
