WRFDA - the Weather Research and Forecasting (WRF) Data Assimilation system, developed at the National Center for Atmospheric Research, is an advanced data assimilation system, which provides state-of-art 3D/4D variational (3D/4D-Var) and hybrid varational/ensemble techniques. It is a component of the WRF modeling system and under the WRF software framework.

WRFDA has become the analysis component of several operational data assimilation systems in the world. It has also found its applications in the research community. The recent developments of WRFDA, in particular the 4D-Var optimization and lateral boundary control, will be presented at the conference.
