WRF-Hydro®

Description

Meta-repository for the WRF-Hydro® modeling ecosystem. For additional information on WRF-Hydro® please visit our official website.

What is WRF-Hydro®?

The WRF-Hydro® modeling system was originally designed as a model coupling framework to facilitate easier coupling between the Weather Research and Forecasting model and components of terrestrial hydrological models. WRF-Hydro is both a stand-alone hydrological modeling architecture as well as a coupling architecture for coupling of hydrological models with atmospheric models. WRF-Hydro is fully-parallelized to enable its usage on clusters and high performance computing systems alike.

Like the WRF model it does not attempt to prescribe a particular or singular suite of physics but, instead, is designed to be extensible to new hydrological parameterizations. Although it was originally designed to be used within the WRF model, it has evolved over time to possess many additional attributes as follows:

The architecture is intended to significantly simplify the often laborious task of integrating, or coupling, existing and emerging hydrological models into the WRF modeling framework. In doing so, an extensible, portable and scalable environment for hypothesis testing, sensitivity analysis, data assimilation and environmental prediction has emerged.

The WRF-Hydro system has adopted a ‘community-based’ development processes with an open and participatory working group environment. NCAR in collaboration with other NSF and university entities are developing a support structure for WRF-Hydro in the way of model documentation, public, online code repositories, test cases and many pre- and post-processing utilities.

What is this repository?

The WRF-Hydro modelling system encompasses many ancillary tools, and we are continually in the process of making these tools available for general community use. This repository serves as a hub for our publically available tools so that they can be more easily discovered. Furthermore, these tools are in varying stages of support and this page indicates the current support level for each tool set.

Tag	Description
