v1.4.0

[TomasTorsvik]

This release maintains backward compatibility with the CMIP6 version of BLOM/iHAMOCC used by NorESM2.

Release highlights

• Major iHAMOCC code re-organization
  • most pre-processor flags ("ifdefs") replaced by logical flags that are read in via namelist
  • all subroutines placed in modules
  • new module mo_param_bgc collects all model parameters and routines for initialization of model parameters
• Major iHAMOCC code style changes (unified indentation, lower-case keywords)
• Added regression testing functionality for BLOM, when run as part of NorESM
• New mechanisms to create namelist files when run as part of NorESM (consistent with other NorESM components), through the file namelist_definition_blom.xml
• New mesoscale eddy diffusivity options
• C-isotope code for sediment now technically supported
• Added support for simulating Ocean Alkalinity Enhancement
