Preprocessing

7. Preprocessing#

Preprocessing phase contains all file and configuration preparation before running the model. Depending on the processes you want to take into account you will need diffrent steps of preprocessing, for example for running an interannual regional run you will first need to define :

  • the grid you will work on

  • the initial and boundary condition you will use

  • enventually the atmospheric, tidal or river forcing you will add

  • …

Two possibilities are available to generate the accurate files :

  • croco_tools : historic tools based on Matlab scripts

  • croco_pytools : tools based on Python scripts

7.1. Matlab Tools : croco_tools#

CROCO preprocessing tools have been developed under Matlab software by IRD researchers (former Roms_tools).

These tools have been made to build easily regional configurations using climatological data. To use interannual data, some facilities are available (NCEP, CFSR, QuickScat data for atmospheric forcing, SODA and ECCO for lateral boundaries). However, to use other data, you will need to adapt the scripts. All utilities/toolbox requested for matlab crocotools programs are provided within the UTILITIES directory, or can be downloaded here: http://www.croco-ocean.org/download/utilities/

The documentation for this toolbox is available at: https://croco-ocean.gitlabpages.inria.fr/croco_tools/

7.2. Python Tools : croco_pytools#

These python tools bring together the methods of several users of the CROCO community but do not constitute a definitive toolbox. A new, more complete toolbox is under development by the CROCO team.

For preprocessing, croco_pytools toolbox consists of prepro directory: a set of python routines, interface with fortran to process the grid and forcing files (initialization, open-boundary conditions, tides forcing, rivers forcing)

The documentation for this toolbox is available at: https://croco-ocean.gitlabpages.inria.fr/croco_pytools/
