     2== Introduction ==
     4The Weather Research and Forecasting (WRF) modelling system is composed of
     5several components which need to be executed sequentially. The manual execution
     6of this workflow is a time-consuming and error-prone task. Thus, it is customary to automate the process to
     7some degree. However, the automation depends on the experiment to be carried
     8out since the workflow depends on the experiment. This leads to the development
     9of specific WRF workflow automation scripts for each experiment. But this is a time consuming task.  When the experiment requires running more
     10than a single model run, the complexity increases and the workflow of the
     11different runs needs to be taken into account. At this point the problems multiply: the large
     12number of simulations now require a monitoring system to check their successful
     13completion; failed runs need to be re-run. If failures are common, the
     14re-running process also needs to be automated. 
     16'''WRF4G''' is a flexible
     17framework to manage the WRF workflow covering a wide range of
     18simulation experiments composed of multiple runs with different degrees of
     19dependence. The framework is layered to separate the experiment design from the
     20execution environment. WRF4G includes a monitoring system and easily restarts
     21broken simulations until the experiment is completed.
