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.
