Evaluating the 3D EnKF - VAR Hybrid Data Assimilation in GSI for Surface and Upper Level Analyses
… the 3 dimensional analysis produced using the Hybrid Ensemble Kalman Filter (EnKF) Variational (VAR) Data Assimilation in the Gridpoint Statistical Interpolation (GSI) System. The data assimilation ingests the 1 hour forecast High-Resolution Rapid Refresh (HRRR) and The Global Ensemble Forecast …

Understanding late Cenozoic western United States mantle dynamics and surface tectonics using forward-adjoint data assimilation models
… the real earth is still not feasible. Different data assimilation methods for mantle simulation therefore have been proposed, all of which have pros and cons. By combining the advantages of the forward and adjoint assimilation algorithms, we created a hybrid data assimilation approach. We …

Efficient formulation and implementation of ensemble based methods in data assimilation
… gained widespread popularity in the field of data assimilation. An ensemble of model realizations encapsulates information about the error correlations driven by the physics and the dynamics of the numerical model. This information can be used to obtain improved estimates of the state of …
