Validation of a PETSc based software implementing a 4DVAR Data Assimilation algorithm: a case study related with an Oceanic Model based on Shallow Water equation
Luisa Carracciuolo, Emil M. Constantinescu, Luisa D'Amore
In this work are presented and discussed some results related to the validation process of a software module based on PETSc which implements a Data Assimilation algorithm.
Statistical Treatment of Inverse Problems Constrained by Differential Equations-Based Models with Stochastic Terms
Emil M. Constantinescu, Noemi Petra, Julie Bessac +1
This paper introduces a statistical treatment of inverse problems constrained by models with stochastic terms. The solution of the forward problem is given by a distribution repres…
An Optimal Experimental Design Framework for Adaptive Inflation and Covariance Localization for Ensemble Filters
Ahmed Attia, Emil Constantinescu
We develop an optimal experimental design framework for adapting the covariance inflation and localization in data assimilation problems. Covariance inflation and localization are…
A scalable matrix-free spectral element approach for unsteady PDE constrained optimization using PETSc/TAO
Oana Marin, Emil Constantinescu, Barry Smith
We provide a new approach for the efficient matrix-free application of the transpose of the Jacobian for the spectral element method for the adjoint based solution of partial diffe…
