Climate Change - Earth and Climate Modeling - Fortran
Published by rem1776 8 months ago

FMS Coupler - 2024.02

[2024.02] - 2024-07-11

Known Issues

  • SPEAR errors have been reported due to a string length being exceeded during the fredb section of the code in the full coupler before initialization. (#136)

Added

  • SIMPLE: Adds option to obtain concurrent drag and heat transfer coefficents via monin_obukhov functions. To control the new option, new namelist options have been added to the surface_flux_nml. The rough_scheme_ocean in ocean_rough_nml must be set to hwrf17 for the options to be effective. (#113)
    • do_iter_monin_obukhov controls whether to iterate over ocean with updated roughness length
    • niter_monin_obukhov controls the number of times to iterate
    • use_u10_neutral if true uses 10m neutral wind rather than the standard 10m wind to obtain rough_mom, rough_heat, and rough_moist

Changed

  • FULL: A number of changes have been made as part of a refactorization effort for the full coupler.
    • A module full_coupler_mod has been added and contains routines and imports previously included in the coupler_main.F90 file. (#104)
    • A new type, coupler_clock type, has been added to handle the usage of any clocks used in the full coupler. This will cause changes in the output order of clock statistics (#106)
    • Updates the written version number to use the version in file_version.h (#109)
    • Refactors atmos_ice_land_chksum and ocean_chksum calls into new routines in full_coupler_mod (#114)
    • Refactors flux_ocean_to_ice and flux_ice_to_ocean calls into new routines in full_coupler_mod (#117)
    • Refactors exchange updates for ice as well as setting ice surface fields and unpacking ocean ice boundary into new routines (#118)
    • Refactors ice surface exchange grid generation into a new routine (#119)
    • Adds a coupler_chksum_type used to compute checksums when do_chksum is true and adds wrapper routines for atmos_tracer_driver_gather_data and sfc_boundary_layer (#123)
    • Refactors update_atmos_model_dynamics, update_atmos_model_radiation, update_atmos_model_down, and flux_down_from_atmos into new routines (#124)
    • Refactors update_land_model_fast, update_ice_model_fast, update_atmos_model_up, flux_up_to_atmos, and update_atmos_model_state into new routines (#125)
    • Refactors unpack_land_ice_boundary, update_ice_model_slow_and_stocks, and update_ocean_model into new routines (#127)
    • Refactors routines for writing intermediate restarts and summarizing timesteps (#128)
  • SHIELD: data_override has been enabled for nest domains (#102)

Removed

  • FULL: Two variables that enabled bugged behaviour from past releases have been removed, ex_u_star_smooth_bug and sw1way_bug. (#99)

Climate Change - Earth and Climate Modeling - Fortran
Published by rem1776 over 1 year ago

FMS Coupler - 2023.02

[2023.02] - 2023-07-28

Fixed

  • SHARED: Fixes crashes due to uninitialized namelist variables.

Changed

  • Routines/variables from FMS have been updated to include a prefixes containing fms and the subdirectory/module name. This was necessitated by aliases being added to the 'global' libFMS.F90 module in FMS.
  • FULL: Adds logic for PE assignment in order to allow for a data atmosphere to be used alongside the combined ice-ocean driver.

Removed

  • Usage of fms_io and mpp_io has been deprecated. If using these modules in a model, you must compile both FMS and FMScoupler with the -Duse_deprecated_io CPP flag.

Climate Change - Earth and Climate Modeling - Fortran
Published by rem1776 almost 4 years ago

FMS Coupler - 2021.02

[2021.02] - 2021-05-20

Added

  • FMS2_IO was implemented to the full coupler:
    - The coupler restart files are now read with fms2_io's ascii_read
    - Ascii writes are now done with fortran's open, close, and write. They are wrapped in an if, so that only the root pe does the io, newunit ensures that the unit number is unique for each file.
    - The variables named unit have been renamed to avoid fortran conflicts.
    - The coupler type restarts are now written with fms2_io.
    - The grid file is now read with fms2_io in: full/flux_exchange.F90:check_atm_grid
  • FMS2_IO was implemented to the simple coupler:
    - Changed ice_model.F90 so that it reads the land_mask files and it reads/writes the ice restart with fms2io.
    - Removed the native formatted restart file code
    - Fms2_io ascii_read is used to read to the coupler_restart
    - Fotran's open, close, and write are used to write the coupler_restart
    - Removed the read_grid_data and get_grid_size subroutines from simple/ice_model.F90. These are never used.
  • Test cases added for varying the latitude of SST maximum in the simple coupler ice model.

Changed

  • Changes all imports from FMS to use the global FMS module and the FMSconstants module
  • Changes to the ice_model restart files:
    • With fms_io, the variables mlon and mlat are written as:
      double mlon(Time, zaxis_1, yaxis_1, xaxis_1) ;
      double mlat(Time, zaxis_1, yaxis_1, xaxis_1) ;
      where:
      xaxis_1 = 1 ;
      yaxis_1 = 1 ;
      zaxis_1 = 1 ;
      Time = UNLIMITED ; // (1 currently)
    • fms_io wrote this as 4d variables as default. In FMS2_io these variables are scalars as they should be. With fms_io, the other non scalar variables where written as:
      double t_surf(Time, zaxis_1, yaxis_2, xaxis_2) ;
      where:
      zaxis_1 = 1 ;
    • In FMS2_io these variables are not a function of the zaxis_1. They are 2d + time as they should be.
      double t_surf(Time, yaxis_1, xaxis_1) ;
      With fms_io, the variables attributes:
      long_name = {The same name as the longname}
      units = "none"
      were written by default.
    • FMS2_io does not do this. Users can specify real long_names and units by calling register_variable_attribute.

Removed

  • FMS_io was almost completely removed from FMScoupler and replaced with fms2_io.

FMS Coupler - Patch release version 2019.01.02

The public interface diag_axis_init has changed in 2020.02 (fms2 work).
One optional argument is added. However this optional argument is required
for the "corner" diagnostics to work.
MOM6/SIS2 developers requsted an interim FMS "release" with just this interface
change so that they can use it to make changes to their dev/gfdl branch that
uses the new interface without actually using fms2 diag_manager.
This update is an attempt to address that request.
