An error estimate of Gaussian Recursive Filter in 3Dvar problem
S. Cuomo, R. Farina, A. Galletti +1
Computational kernel of the three-dimensional variational data assimilation (3D-Var) problem is a linear system, generally solved by means of an iterative method. The most costly p…

A Revised Scheme to Compute Horizontal Covariances in an Oceanographic 3D-VAR Assimilation System
R. Farina, S. Dobricic, A. Storto +2
We propose an improvement of an oceanographic three dimensional variational assimilation scheme (3D-VAR), named OceanVar, by introducing a recursive filter (RF) with the third orde…

A PCG Implementation of an Elliptic Kernel in an Ocean Global Circulation Model Based on GPU Libraries
Salvatore Cuomo, Pasquale De Michele, Raffaele Farina +1
In this paper an inverse preconditioner for the numerical solution of an elliptic Laplace prob- lem of a global circulation ocean model is presented. The inverse preconditiong tech…
