How to use the cheat-sheet for plugins

The following sections require using plugins and providing their specifications. Arguments for each plugin are documented on its individual documentation page. To make finding plugins easier, the cheat-sheet organizes them by type (the leftmost column, e.g. chemistry, controlvect, fields). For each type, available plugins are listed with their name and version. Specifying a plugin’s name and version is mandatory; specifying its type is not always necessary.

1.1. Domain#

The up to 4 files defining the simulation domain can be generated as explained in making a new domain.

For a horizontal or vertical grid that is not pre-coded, the relevant files can be written manually.

The domain must be generated using a simple YAML as shown in the tutorial above, or created by hand, or taken from ready-made files. The domain is then used when generating all other inputs.

1.2. Chemistry#

The 12 files defining a chemical scheme for CHIMERE are not pre-processed by the CIF. See the dedicated documentation to create them, or use one of the existing schemes.

1.3. Meteorology#

The CIF can pre-process ECMWF grib files into the format required by CHIMERE.

The recommended approach is to generate the required METEO.nc files in advance, as explained in generating meteo from ECMWF, and store them. Note that pre-processing the meteorology requires a domain to be defined first.

Their content should be checked with plots, maps, etc.

The simulations can afterwards point to these METEO.nc files, as shown in the tutorial for a simulation from ready-made files.

1.4. Emissions#

The CIF can pre-process various raw files into the format required for CHIMERE’s AEMISSIONS and BEMISSIONS, as explained in generating emission files from raw data.

It can also combine ready-made files, as explained here.

Both approaches can be combined, as shown in One species (among several) taken from a raw inventory on one level.

1.5. Boundary conditions#

The CIF can pre-process various raw files into the format required for CHIMERE’s INI_CONCS and BOUN_CONCS, as explained in generating boundary conditions from raw data.
