release-noresm2.0.4

(this release is identical to release-noresm2.0.3 except for an additional modification in CIME related to Fram machine. We therefore repeat here the information mentioned in release-noresm2.0.3.)

Version of code which can be used to reproduce the CMIP6 results of NorESM2. This release builds on the four former releases.

This release contains

• modified setting for machine Fram : minor changes due to removal of preproc queue (this is the only change compared to release-noresm2.0.3)
• settings to run on the machine Betzy
• automatic copying of the case directory to the archive directory
• updated documentation
• modifications in the ocean component BLOM (see a list of main changes below)

Notable changes of BLOM v1.1.0 compared to v1.0.0 that has impact on BLOM operation as a component of NorESM

• Added NorESM multiple instance support.
• Corrected time-smoothing of forcing fields received through the coupler so it works for any coupling interval.
• Corrected the generation of BLOM/iHAMOCC input data list.
• Added handling of N-deposition files for N2000 compsets.
• Major restructuring of code to replace header files and common blocks with Fortran modules.
• Added new pe-layout for OMIP1 compsets with iHAMOCC using the tnx2 grid.
• Added support for tripolar ocean grid with 1/8 deg resolution along equator (tnx0.125v4).
