LMDZ/mass-fluxes-acc LMDZ/mass-fluxes-acc#

Description#

Legacy meteorology plugin for LMDZ’s monthly mass-flux NetCDF files (defstoke, fluxstoke, fluxstokev, phystoke), using an accumulated (-acc) time-stepping scheme superseded by the newer lmdz_mass_fluxes (mass-fluxes) plugin.

The single defstoke.nc file (holding the LMDZ physics time step information) can be located either alongside the other monthly files or at a custom path given via defstoke_file.

YAML arguments#

The following arguments are used to configure the plugin. pyCIF will return an exception at the initialization if mandatory arguments are not specified, or if any argument does not fit accepted values or type:

Optional arguments#

dir : str, optional, default “”

Path to the corresponding component. This value is used if not provided in parameters

file : str, optional, default “”

File format in the given directory. This value is used if not provided in parameters

varname : str, optional, default “”

Variable name to use to read data filesinstead of the parameter name if different to the parameter name

file_freq : str, optional, default “”

Temporal frequency to fetch files

split_freq : str, optional

Re-bucket this tracer’s fetched dates/files onto a fixed pandas-frequency grid (e.g. '1D', '1MS', '1YS'), independently of the native frequency the files were found at (file_freq). This fixes the sub-simulation boundaries that fromcontrol inherits for this tracer. For minimal memory usage, match it to the consuming model’s own periodicity: a finer value costs an extra time_interpolation bridge for no memory benefit, while a coarser value keeps the tracer’s data resident in memory across every one of the model’s sub-simulations it spans. See the ‘Splitting the temporal grid’ section on the observation operator page for the full mechanism and worked examples.

defstoke_file : str, optional

Path to the ‘defstoke.nc’ file if it is in a different location
