Variational Data-Consistent Assimilation
Rylan Spence, Troy Butler, Clint Dawson
This work introduces a new class of four-dimensional variational data assimilation (4D-Var) methods grounded in data-consistent inversion (DCI) theory. The methods extend classical…

Sequential Maximal Updated Density Parameter Estimation for Dynamical Systems with Parameter Drift
Carlos del-Castillo-Negrete, Rylan Spence, Troy Butler +1
We present a novel method for generating sequential parameter estimates and quantifying epistemic uncertainty in dynamical systems within a data-consistent (DC) framework. The DC f…
