WRF for GRID (WRF4G) is a framework for the execution and monitoring of the WRF Modelling System in distributed computer resources (see this presentation). It provides a flexible and easy way of designing complex experiments involving many simulations (multiple start/end dates, multiparametric simulations, long climate runs, ...). The monitor allows a precise control of the state of the experiment, where broken simulations are automatically detected and relaunched on the next submission. The computer resources the user can access are managed transparently and used to run the experiment assigned to them. Remote desktop computers, workstations, clusters, etc. can be merged and used at the same time to run different simulations of a WRF experiment.

As another source of computer resources, the GRID provides transparent access to geographically distributed computational and storage resources. Several applications areas as high energy physics or bio-applications have benefited from this computational paradigm. These applications are organized around communities known as virtual organizations (VO). WRF4G is being deployed in different GRID initiatives: EELA2 project and Spanish e-Science network. See the EGEE'09 press note.
