v1.6.0

This release is intended as default BLOM/iHAMOCC component for NorESM2.3.

Release highlights

  • BLOM default to use MKS units
  • BLOM default to use new eddy parameterization
  • iHAMOCC: First release with extended nitrogen cycle (optional)
  • iHAMOCC: Include preformed Si tracer
  • Include new external package M4AGO (optional new sinking scheme in iHAMOCC)

Run BLOM/iHAMOCC with CMIP6 circulation

This release changes default settings in BLOM/iHAMOCC. See the BLOM wiki for settings needed to run the v1.6 version of BLOM/iHAMOCC in a configuration that is equivalent to the CMIP6 version of the model.

Externals_BLOM.cfg

package tag
CVMix v0.98-beta
M4AGO dev-1.0.0

Component (updated/not updated) relative to v1.5.1

NOTE: The inclusion of M4AGO as an external dependency may require checking out a clean version of the source code, as the checkout_externals script will sometimes fail to check out this code with old source code versions.

v1.4.0

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

v1.3.0

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

Release highlights

  • Include option for hybrid vertical coordinates
  • Include option for sediment spinup
  • Include support for NUOPC driver
  • iHAMOCC source code structure:
    • completed conversion to free-source format
    • explicit use statements for all imported variables

Changes in model structure

The hybrid vertical coordinate formulation relies on an external package CVmix, which is included as a git submodule. When building NorESM, the external dependency should be declared in the Externals.cfg file:

[blom]
...
externals = Externals_BLOM.cfg

Changes in model diagnostics

Some of the model output diagnostics have changed in this release, either due to structural changes or bug fixes. Please use v1.2.0 if you need the older versions of these output fields.

BLOM

  • Starting from commit 9e6bd6b, which introduced hybrid vertical coordinates, model output changed for the following 4 fields:
wflx : vertical mass flux
wflx2 : vertical mass flux squared
bfsq : buoyancy frequency squared
bfsqlvl: buoyancy frequency squared (constant depth levels)
  • Pull request #205 included a correction on the variable dp_trc :
dp_trc : This variable is supposed to in unit Pa = kg m-1 s-2 but is wrongly output in unit g cm-1 s-2.

iHAMOCC

  • Pull request #202 changed the definition of the variable KWCO2, with the original definition retained in a new variable KWCO2KHM :
Original definition table:
! KWCO2 - Piston velocity times solubility (kwco2*kh; moist air) [m s-1 mol kg-1 uatm-1]

New definition table:
! KWCO2 - Piston velocity (kwco2) [m s-1]
! KWCO2KHM - Piston velocity times solubility (kwco2*kh; moist air) [m s-1 mol kg-1 uatm-1]
