DART: Tools and Support for Ensemble Data Assimilation Research, Operations, and Education
This poster focuses on recent developments for coupled data assimilation with DART and NCAR's Community Earth System Model. DART interfaces to the Community Atmosphere Model (CAM), the Parallel Ocean Program (POP) and the Community Land Model (CLM) can now be used to do multiple component data assimilation with the fully-coupled CESM prediction model. The software innovations required to enable this are described. The latest results for ensemble assimilation experiments with each of the component models are presented along with initial comparisons to corresponding assimilations with the coupled model. A newly developed DART interface to the Whole Atmosphere Community Climate Model (WACCM) is now available. An overview of results of the relative value of assimilating tropospheric and middle atmosphere observations in WACCM is presented.
DART is also used with many other types of geophysical models. Highlights of the latest results using DART with the Weather Research and Forecasting (WRF) model for springtime weather over the central United States are also presented.
The poster includes instructions on how to get started using DART for research or educational applications.
