A Time-parallel Approach to Strong-constraint Four-dimensional Variational Data Assimilation
Vishwas Rao, Adrian Sandu
A parallel-in-time algorithm based on an augmented Lagrangian approach is proposed to solve four-dimensional variational (4D-Var) data assimilation problems. The assimilation windo…
