DART

The Data Assimilation Research Testbed (DART) implements many ensemble assimilation methodologies including the Ensemble Kalman Filter (Evensen, 2003) 1 and the Ensemble Adjustment Kalman Filter (Anderson, 2001). 2

Forward operators required to assimilate observations perform line-of-sight integration, volume integration, interpolation, and other common techniques.

These forward operators are optimized given the grid structures and the parallelization scheme.
