The ESMValCore package provides the
esmvaltool command line tool, which can
be used to run a recipe.
To run a recipe, call
esmvaltool run with the desired recipe:
esmvaltool run recipe_python.yml
If the configuration file is not in the default location
~/.esmvaltool/config-user.yml, you can pass its path explicitly:
esmvaltool run --config_file /path/to/config-user.yml recipe_python.yml
It is also possible to explicitly change values from the config file using flags:
esmvaltool run --argument_name argument_value recipe_python.yml
To automatically download the files required to run a recipe from ESGF, set
false in the User configuration file
or run the tool with the command
esmvaltool run --offline=False recipe_python.yml
This feature is available for projects that are hosted on the ESGF, i.e. CMIP3, CMIP5, CMIP6, CORDEX, and obs4MIPs.
To control the strictness of the CMOR checker, use the flag
esmvaltool run --check_level=relaxed recipe_python.yml
Possible values are:
ignore: all errors will be reported as warnings
relaxed: only fail if there are critical errors
default: fail if there are any errors
strict: fail if there are any warnings
To run a reduced version of the recipe, usually for testing purpose you can use
esmvaltool run --max_datasets=NDATASETS --max_years=NYEARS recipe_python.yml
In this case, the recipe will limit the number of datasets per variable to NDATASETS and the total amount of years loaded to NYEARS. They can also be used separately. Note that diagnostics may require specific combinations of available data, so use the above two flags at your own risk and for testing purposes only.
To run a recipe, even if some datasets are not available, use
esmvaltool run --skip_nonexistent=True recipe_python.yml
It is also possible to select only specific diagnostics to be run. To tun only one, just specify its name. To provide more than one diagnostic to filter use the syntax ‘diag1 diag2/script1’ or ‘(“diag1”, “diag2/script1”)’ and pay attention to the quotes.
esmvaltool run --diagnostics=diagnostic1 recipe_python.yml

ESMValTool command line interface is created using the Fire python package. This package supports the creation of completion scripts for the Bash and Fish shells. Go to https://google.github.io/python-fire/using-cli/#python-fires-flags to learn how to set up them.
