2022

New in CROCO v1.3 (November 2022)

CROCO v1.3 is recommended for users of PISCES, MUSTANG and the coupling toolbox. In addition it includes correction of critical bugs, inconsistencies and light improvements

Environment

  • Little updates on create_config.bash : mostly comments and some little bugfixes

Coupling

full description : https://croco-ocean.gitlabpages.inria.fr/croco_doc/model/model.coupling.html and https://croco-ocean.gitlabpages.inria.fr/croco_doc/tutos/tutos.16.coupling.html

  • put by default exchanges of AVERAGE fields over the coupling timestep
  • add possibility to use coupling with WRF moving nests (coupling only on the parent domain, and interpolation in WRF between the parent and moving nest for ocean surface conditions => requires to use the last version of WRF in the WRF-CROCO github fork)
  • some corrections for coupling with a toy model
  • add the possibility to create oasis restart files from pre-existing model outputs
  • coupling scripts: correct some typos, comments, and directory and grid names for oasis files and oce_compile for AROME and ECMWF

Sediment

full description : https://croco-ocean.gitlabpages.inria.fr/croco_doc/model/model.modules.sediment.html

  • Test and reorganise flocculation capabilities. FLOCMOD module is present in MUSTANG and in SEDIMENT with equal routines. To avoid redundancies and clarify maintenance/dev on this module, an independent module has been be created, flocmod.F90 with interfaces in MUSTANG/SEDIMENT

Numerics and parametrisations

full description : https://croco-ocean.gitlabpages.inria.fr/croco_doc/model/model.numerics.html

  • UV_HADV_UP5: change to apply UP5 to both predictor and corrector time steps to avoid checkboard noise detected in regional simulations (thanks to J. Gula)
  • GLS_MIXING: add limitation in potential flow region following Larsen and Fuhrman (2018), to prevent the instable growth of turbulent viscosity for non-breaking external or internal waves

New Configurations

full description : https://croco-ocean.gitlabpages.inria.fr/croco_doc/model/model.test_cases.html

  • 1 new test cases for sediment processes (can be used with USGS or MUSTANG sediment model) :a schematized estuary (from MARS corresponding test case). From TIDAL_FLAT, the grid is set to 200×90 then the cells sizes are fixed to dx = 600m and dy = 100m. The OBC West is the same as in TIDAL_FLAT. The bathymetry is derived from MARS code with the same parameters. A river is placed on the East side with sediment input (400m3/s – 50mg/L of MUD)

Pisces

  • fix various bugs and improve robustness

Runoff

Possibility to add a source point as a volume vertical influx. With this feature there is no need to take care of the position of the source with the mask and a source can be added anywhere on the grid. The outflow is applied at rho point (cpp key PSOURCE_MASS)

Miscellaneous

  • run_croco scripts: some corrections for adequation with prod env, comments and re-organization
  • NC4 for diagnostics
  • Some fixes when writing into existing diagnostics files (diag TS, diag Momentum, Vorticity, PV, EK, PV, VRT…)
  • Various fixes when using NC4PAR
  • Move Surface atmospheric forcing and Lateral forcing cpp-keys upper in cppdefs.h
  • Output in double precisions in case of PARALLEL_FILES (to be compatible with ncjoin)
  • Put back by default previous partit.F to handle with FRC_FRY
  • Changes in compilations options for ifort and gfortran

CROCO_TOOLS

  • Improve octave compatibility
  • Add global attribute in netcdf files (notably: origin date)
  • Tides: add the possibility to create frc files with tides only, and add a routine to create tide-only frc files for interanual simulation
  • Add pre-processing scripts for downlading glorys oceanic reanalysis data.
  • Coupling: add scripts to create weight files and smoothing for the coupler (interpolation between model grids), some corrections in pre-processing for WWIII for adequations with more recent versions of WWIII, and some other minor corrections in scripts
  • Biology: Pre-processing scripts have been moved to Preprocessing_tools/Bio. Update some scripts to handle PISCES-quota
  • Nesting_tools: some small corrections

Bugfix release 1.2.1

Intermediate release v1.2.1 is fixing some bugs in v1.2

Here are the bugfix corrections :

  • ONLINE bulk: wind speed was not properly computed, with a consequent understimation of fluxes when using bulk ONLINE. This is now corrected
  • Runoff : Msrc parameter in param.h was wrongly set to 0, it is now corrected and set to 100
  • Plurimonth_scripts: DT was wrongly intialized with nesting. This is now corrected.
  • In 2D cases, the size of wrthis array was wrong. This is now corrected.
  • A typo in def_diags has been corrected
  • CVTK: some continuous integration tests have been updated

New in CROCO 1.2

Environment

The whole structure of the repository has been updated, please read carefully. It comes with a new set of scripts to help to launch production simulations. See https://croco-ocean.gitlabpages.inria.fr/croco_doc/tutos/tutos.02.contents.html for details.

  • create_config.bash: script to create a configuration environment. 2 typical modes are proposed: all-dev for the usual (“all-in”) architecture for forced CROCO runs and/or dev, and all-prod/all-prod-cpl for production run architecture and coupling with external models
  • SCRIPTS/ directory: where scripts for running croco in production mode are provided
  • croco input and output files for interannual simulations can now be named systematically with 2 digits for month: croco_…Y????M??.nc instead of croco…_Y????M?.nc (the old option is however still available)
  • croco/XIOS/process_xios_xml.sh : stand-alone cpp-process of the XIOS xml files. It is now separated from the jobcomp script. It is deployed in Run/ in all-dev setup, and in CONFIGS/PREPRO/XIOS/ in all-prod setup

2019

25 October 2019 : CROCO V1.1 RELEASE

CROCO stable release V1.1 (25 October 2019):  Download croco-v1.1

  • CROCO_TOOLS stable release V1.1 (25 October 2019):  Download croco_tools-v1.1

    • Reminders:

    CROCO sources and CROCO_TOOLS (the follow-on of ROMS_TOOLS) are now distributed separately (for croco_tools releases, see associated tab at https://www.croco-ocean.org/download/croco-project ). ROMS_AGRIF is not maintained anymore and we strongly encourage ROMS_AGRIF users to switch to CROCO. CROCO version available directly from the git repository is an unstable development version. Standard users should use the stable one downloaded from the web site.

    New in v1.1 :
    • architecture : slight changes
      • CROCO doesn’t come with a default Run directory anymore, first step as a user will be to run the script create_run.bash to create your own
      • as a consequence TEST_CASES files are now stored in croco/TEST_CASES and the scripts for running the model in croco/SCRIPTS
    • parallelisation : in MPI (not OPENMP), CROCO now has the capacity to save computation in MPI partitions set over land. A pre-processing step is required. The corresponding tool is located under croco/MPP_PREP : the namelist has to be filled with the maximum number of CPUs available, then compile and execute the code. It returns the optimal partitioning parameter values for NP_XI, NP_ETA and NNODES.
    # define MPI
# define MPI_NOLAND   (default undef)
    • outputs :
      • NetCDF4 parallel capability is available. When running with MPI activated, the outputs are stored in a single file (different from PARALLEL_FILES) but faster than with serial netcdf writing.
      # define MPI # define NC4PAR (default undef)# define MPI # define XIOS (default undef)
    • diagnostics : several budget equations added. Each of them has its corresponding section in croco.in.
      • vorticity :
      # define DIAGNOSTICS_VRT
      • eddy kinetic energy :
      # define DIAGNOSTICS_EK
      • potential vorticity
      # define DIAGNOSTICS_PV
    • grid : the resolution of a mesh can be locally refined to account for a section reduction (example : keep realistic sections for an under-resolved river canal in a realistic configuration)
    # define REDUC_SECTION  (default undef)`
    • bottom friction :
      • Spatialisation of roughness length Z0 coefficient
      # define Z0B_VAR (default undef)
      • Use sub-timesteps for computation of fast bottom friction. In this case, bottom friction is computed in step3d_fast routine
      # default BSTRESS_FAST `
    • functional : Use of calendar to define start and end date : The user can choose the beginning and the end of the simulation in croco.in , then the number of time steps will be calculated. Also print the date at each time step in screen log.
    # define USE_CALENDAR   (default undef)

    adding additional lines in croco.in : run_start_date: 01/04/2015 00:00:00 run_end_date: 12/04/2015 00:00:00

    • atmospheric forcing :
      • Use MeteoFrance inputs (Arome/Arpege) for online atmospheric reading and interpolation
      # define AROME (default undef)
      • Read atmospherical pressure from meteo files, use it in bulk flux and apply atmospherical pressure gradient in the momentum equations
      # define READ_PATM (default undef)
      • Current feedback added in bulk and forcing cases. Three possibilities: feedback on the stress (CFB_STRESS, default) using a coefficient based on the wind speed, or based on the wind stress (CFB_STRESS2), or feedback on the wind speed (CFB_WIND, less physical)
      # define SMFLUX_CFB (default undef)
    • ocean/wave coupling : add wave average outputs. Add wave-to-ocean stress accounting for wave model bulk
    • tides : Introduction of a new method for harmonic composition : use of Simon (SHOM) method to build tide elevation from harmonic constituents.
    # define TIDES_MAS    (default undef)
    • open boundaries : reduced-form equation for barotropic velocities at boundary conditions in case when tidal currents are not available (#undef UV_TIDES). It’s also useful for test cases, forcing the model with analytical sea surface elevation (for example a M2 tide). In both cases it replaces M2_FRC_BRY (in this case set #undef M2_FRC_BRY to avoid confusion) and it works with M2FLATHER and M2CHARACT obc conditions. This development comes from ROMS-Rutgers source code. This option has been tested in a tidal flat test case for each open boundary condition (north, south, west and east)
    # define OBC_REDUCED_PHYSICS (default undef)

    OBC_M2FLATHER was suppressed (redondant with OBS_M2CHARACT). Use OBS_M2CHARACT instead.

    • vertical mixing : GLS scheme was rewritten. GLS_MIX2017 cpp key was suppressed and only GLS_MIXING stays.
    #define GLS  (KEPSILON model and CANUTO stability function are chosen by default if no other key selected in cppdefs.h)

    Dedicated configuration : SINGLE_COLUMN, a 1D vertical model with several subsettings to test.

    • test cases : additions/changes
      • I_SOLITON : was previously within GRAV_ADJ (#define GRAV_ADJ_SOLITON)
      • FLUME : now SANDBAR
      • TS_HADV_TEST : new case to test horizontal advection for tracers

      • # define  VADV_ADAPT_IMP
    • GLS turbulent closure sub-model (in addition to KPP)  
      • # define GLS_MIXING_2017
    • Wave‐induced (non breaking) vertical mixing in KPP modified according to Wang et al. (JGR 2010) based on Qiao et al (JPO 2004)

    • Basic 3D Smagorinsky model for LES-type applications   
      • # define UV_VIS_SMAGO_3D (with NBQ)
    • Built-in diffusion in barotropic time stepping as an alternative to fast mode filtering (used in NBQ applications)  
      • # define M2FILTER_NONE
    • Updated PISCES version (Aumont et Bopp, GBC 2006)  
      • # define PISCES
    • New vertical coordinate (not dependent on minimum depth), by default,  suited for decreasing pressure gradient errors in the thermocline above steep topography (Shchepetkin and McWilliams, 2009)
      • # define NEW_S_COORD
    • Dedicated log output file croco.log
      • # define LOGFILE

    ROMS_AGRIF  is not maintained anymore and we strongly encourage ROMS_AGRIF users to switch  to CROCO.

    2016

    • 4 Feb. 2016 : In Aforc_NCEP/, if you were using the ROMSTOOLS v3.1.1, there was a bug in the download_CFSR.m routines.
      • We were downloading heat fluxes variable for Upward Long wave, Downward and Upward Short wave. We were using the variables AT THE TOP OF THE ATMOSPHERE that was inducing large biais in SST in all the CFSR simulation. To use the right fluxes at THE SURFACE OF THE OCEAN, the vname values in download_CFSR.m
        -Upward_Long-Wave_Rad_Flux_surface
        -Downward_Short-Wave_Rad_Flux_surface
        -Upward_Short-Wave_Rad_Flux_surface
      • Here are the fixes:
        download_CFSR.m.fix.6fev2016 5.73 kB interp_CFSR.m.fix.6fev2016 4.57 kB
