Purpose, Description

This is the Modular ocean model (MOM5) component of the IOW ESM. The starting point for the IOW ESM development was a IOW-adapted version of the code that is originating from the following commit on https://github.com/mom-ocean/MOM5

Versions

1.01.01 (latest release)

date	author(s)	link
2023-07-24	SK	1.01.01

changes

• apply albedo for direct and diffusive radiation directly in MOM and not in the flux_calculator

dependencies

• OASIS3-MCT libraries
• see build scripts for more dependencies

known issues

• in coupled model this version leads to too cold winter temperatures when evaluated from 1959-201
  • tested bias corrections can improve on that
• model is not running on phy-2
• Caution: this code is not compatible with current 8nm example setups!
  • 8nm examples have to be updated according to version 1.01.00

tested with

• intensively tested on both HLRN machines
  • using example setups available under: (coupled) /scratch/usr/mviowmod/IOW_ESM/setups/ MOM5_Baltic-CCLM_Eurocordex/example_3nm_0.22deg/1.00.00 and https://zenodo.org/record/8167743/files/1.00.00.tar.gz (https://doi.org/10.5281/zenodo.8167743)
    (uncoupled) /scratch/usr/mviowmod/IOW_ESM/setups/ MOM5_Baltic/example_3nm/1.00.00
  • results exhibit known issues
  • can be built and run on Haumea but output is not intensively tested

older versions

1.01.00

2022-12-22	SK	1.01.00

changes

• updated ERGOM module to newest available version
  • Caution: this code is not compatible with current 8nm example setups!
  • 8nm examples have to be updated as well
• build with compiler flags that lead to more stablility (not so many NaN problems)

dependencies

• OASIS3-MCT libraries
• see build scripts for more dependencies

known issues

• in coupled model this version leads to too cold winter temperatures when evaluated from 1979-2009
• model is not running on phy-2

tested with

• intensively tested on both HLRN machines
  • using example setups available under: (coupled) /scratch/usr/mviowmod/IOW_ESM/setups/ MOM5_Baltic-CCLM_Eurocordex/example_3nm_0.22deg/1.00.00 (uncoupled) /scratch/usr/mviowmod/IOW_ESM/setups/ MOM5_Baltic/example_3nm/1.00.00

1.00.00

date	author(s)	link
2022-01-28	SK, HR	1.00.00

changes

• initial release
• main codes is based on branch 5.1.0 on https://github.com/mom-ocean/MOM5.git
• coupling interface has been implemented by authors
• adapted Fopts and added build scripts for
  • both HLRN supercomputers
  • Rostock University's cluster Haumea
  • for IOW phy-2 machine (model is not running here)
• added OASIS interface to flux calculator
  • send SST, fraction of ice and albedo
  • send variables to calculate fluxes for evaporation, latent and sensible heat, momentum
  • receive radiation and precipitation
  • receive calculated fluxes in corresponding variables that have been fed by forcing data in the uncoupled mode
• executable can run in coupled model or as stand alone
  • use parameter type_atmos='flux_calculator' in coupler_nml in input.nml for control, see also documentation in iow_esm/main project
