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 Add MACHINFO and ENVINFO #323 Add lcov code coverage tool #324 Documentation: Update version number and interface documentation #335 Update citation information #327 Correct Pstar units #325 General documentation updates
