3.3. NorESM2.0.6

  • Repository: NorESMhub/NorESM

  • Tag: release-noresm2.0.6

  • Commit:

  • Released by: DirkOlivie

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

3.3.1. This release contains:

  • updated NorESM2 documentation

  • addition of extra compsets : new SSP5-3.4 compsets and emission driven SSP compsets (affects CAM-Nor, CLM and NorESM)

  • CAM-Nor

    1. technical (non answer-changing) modifications in CAM-Nor : correction in CCN and COSP diagnostics;

    2. correction in H2O emission file link for f09 for the extended (year 2100-2300) SSP1-2.6 and SSP5-8.5 compsets;

    3. addition for the above-mentioned extra compsets.

  • CLM

    1. addition for the above-mentioned extra compsets.

  • CIME

    1. modification in archiving script noresm2netcdf4.sh : uses ncks instead of nccopy;

    2. other small modifications.

  • CISM

    1. link to cism-wrapper repository on NorESMhub (instead of ESCOMP)

    2. added CISM support, Greenland enabled compsets and usermod

  • BLOM

    1. include option for hybrid vertical coordinates;

    2. include option for sediment spinup;

    3. include support for NUOPC driver;

    4. iHAMOCC source code structure : completed conversion to free-source format and explicit use statements for all imported variables;

    5. modifications 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 for BLOM in the Externals.cfg file : externals = Externals_BLOM.cfg;

    6. changes in model diagnostics in 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) and bfsqlvl (buoyancy frequency squared (constant depth levels));

    7. changes in model diagnostics in BLOM. Pull request #205 included a correction on the variable dp_trc : this variable is supposed to be in unit Pa = kg m-1 s-2 but is wrongly output in unit g cm-1 s-2;

    8. changes in model diagnostics in iHAMOCC. Pull request #202 changed the definition of the variable KWCO2, with the original definition retained in a new variable KWCO2KHM.

3.5. NorESM2.0.4

  • Repository: NorESMhub/NorESM

  • Tag: release-noresm2.0.4

  • Commit: d8c5cec

  • Released by: DirkOlivie

This release is identical to release-noresm2.0.3 except for an additional modification in CIME related to Fram machine and the –pecount option for betzy. 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.

3.5.1. 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)

3.5.2. 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).

3.7. NorESM2.0.2

  • Repository: NorESMhub/NorESM

  • Tag: release-noresm2.0.2

  • Commit: 6581d10

  • Released by: DirkOlivie

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

3.7.1. This release contains:

  • updated documentation

  • bug fixes such that model runs without intermittent crashes on certain machines (nebula, tetralith)

  • automatic download of NorESM-specific inputdata from noresm.org/inputdata

  • indication of which grids are supported for individual compsets

  • modification in the inputdata structure of BLOM

  • extra usermods_dir for keyCLIM simulations and extra compsets for covid simulations

3.7.2. Additional features:

  • restart files for some compsets can now be found on noresm.org/restart

3.7.3. Notice

  1. automatic download of inputdata from noresm.org to certain machines (e.g. nebula) might not work completely as expected. This can partially be solved by or :

    1. change the listed order of servers in cime/config/cesm/config_inputdata.xml : move the cesm-inputdata server before the noresm.org server; or

    2. run ./check_inputdata twice; or

    3. submit the job twice (./case_submit).

  2. reproducing CMIP6 results

    1. on vilje and fram for atmosphere-only compsets (like NF1850norbc, NFHISTnorpibc, …) : this can be obtained by commenting out in cam/src/chemistry/mozart/chemistry.F90 line 1310 : ncldwtr(:,:) = 0._r8

    2. on vilje and fram for fully-coupled simulations (like N1850, NSSP245frc2, …) : we have kept the -init=zero,arrays compiler settings for CAM on fram and vilje

    3. one should use the same number of processor as in the original simulation

  3. it is possible that some NorESM-specific inputdata is missing on noresm.org/inputdata. If that happens, please make an issue, and we will try to upload the missing data.
