Template plugin for fluxes flux/template#

Description#

This is a template to write a flux plugin. It includes all required functions to run properly.

It generates random values and can be directly used with a working test case.

Warning

Please gradually document your plugin properly when starting from the template. It includes input_arguments (see here for details), as well as all information about the original data the plugin is supposed to accommodate.

Please include licensing information, permanent link to download the data (or a contact person if no link is publicly available), as well as data format (temporal and horizontal resolution, names and shape of the data files), and any specific treatment that prevents the plugin from working with another type of files.

Summary steps to integrate a new flux data plugin#

First steps to integrate your own flux plugin from the template#

To integrate your own flux plugin, please follow the steps:

  1. copy the flux_plugin_template directory into one with a name of your preference

  2. Start writing the documentation of your plugin by replacing the present docstring in the file __init__.py. Use rst syntax since this doctring will be automatically parsed for publication in the documentation

  3. Change the variables _name, _version (default is std) if not specified, and _fullname (optional, is used as a title when automatically generating the documentation here)

Now your new plugin is ready to be used in your test case with random data.

Further integration of your own plugin#

Now that your plugin can be used in a yml and generate random values, you need to integrate the main functions feeding the plugin.

  • fetch: fetch data files

  • read: read data files

  • write: write data files

Please find further details here.

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 “1D”

The time frequency at which data files are available.

split_freq : str, optional

Force splitting the processing at a given frequency different to file_freq

dummy_arg : str, optional, default “let’s say it’s not mandatory”

document here the argument

lon_min : float, optional, default -180

Minimum longitude

lon_max : float, optional, default 180

Maximum longitude

lat_min : float, optional, default -90

Minimum latitude

lat_max : float, optional, default 90

Maximum latgitude

nlon : int, optional, default 90

Number of grid cells in the zonal direction

nlat : int, optional, default 45

Number of grid cells in the meridional direction

nlev : int, optional, default 1

Number of levels in the data

average_value : float, optional, default 1

Average value for the generation of random values

std_value : float, optional, default 1

Standard deviation value for the generation of random values
