Configuration generator for WRF namelists
Project description
wrfconf
A commandline tool for generating WRF configuration from structured YAML files.
The purpose of this package is to be able to easily generate WRF and WPS namelists in an extensible manner. Namelists are generated from configuration files which can be source controlled and include additional metadata not present in the namelist
Quick start
wrfconf can be installed using pip:
pip install wrfconf
Before the WRF and WPS namelists can be generated, a yaml file describing the time, domain and physics settings. This can be generated using python or other scripting language or manually edited. Once you have a configuration file, namelist.input and namelist.wps can be generated by:
- ::
wrfconf create ../examples/run.yml
Configuration file
An example YAML file is included in examples/run.yml:

There are a number of top level keys in these configuration files:
meta
This section includes metadata about the run and does not impact the generated namelists. Any valid YAML can be included in this section
run_info
Information specific to this particular run, such as the start time and length of run
domain
Domain specific information
wps
Override any attributes in the WPS file. This section follows the same structure and naming conventions as in a WPS file
wrf
Override any attributes in the WRF namelist. This section follows the same structure and naming conventions as in a WRF namelist file
Development setup
git clone https://github.com/lewisjared/wrfconf.git cd wrfconf python setup.py develop
