Introduction

WRF4G is a framework for executing and monitoring weather and climate experiments with the WRF Modeling System (see this presentation) for an introduction to WRF). It provides a flexible and easy way of designing complex experiments involving many simulations (multiple start/end dates, multi-ensemble simulations, long climate runs and so on). The monitor allows a precise control of the experiment's state, where broken simulations are automatically detected and relaunched at the next submission.

Given a list of computing resources that the user can access, WRF4G submits the experiment to them according to the experiment needs. Users can configure different (Distributed Computing Infrastructures (DCIs) such as HPC, Grid and Cloud resources. The output files are going to be stored depending on the resources used to run the simulations.

First steps with WRF4G

The current version of WRF4G (3.0.0) can be installed in any Linux machine using the wrf4g pip package. If you want to try new features, you can download the source code from the WRF4G github site.

If you are still using WRF4G 2.0, we encourage to upgrade to version 3.0. Documentation of WRF4G 2.0 can be accessed from the old WRF4G site.
