WRF Data Assimilation System Users Page
Welcome to the page for users of the Weather Research and Forecasting (WRF) model data
assimilation system (WRFDA). The WRFDA system is in the public domain and is freely available for community
use. It is designed to be a flexible, state-of-the-art atmospheric data assimilation system that is portable
and efficient on available parallel computing platforms. WRFDA is suitable for use in a broad range of
applications, across scales ranging from kilometers for regional and mesoscale modeling to thousands of
kilometers for global scale modeling.
The Mesoscale and Microscale Meteorology (MMM) Division of NCAR currently maintains and
supports a subset of the overall WRF code (Version 3) that includes:
- WRF Software Framework (WSF)
- Advanced Research WRF (ARW) dynamic solver, including one-way,
two-way nesting and moving nests, grid and observation nudging
- WRF Pre-Processing System (WPS)
- WRF Data Assimilation System (WRFDA) (found on this site)
- Numerous physics packages contributed by WRF partners and the research community
Other components of the WRF system will be supported for
community use in the future, depending on interest and available resources.
