SABER is the System Agnostic Background Error Representation.

It provides generic software utilities for computing and working with the background error covariance matrix, often referred to as the B matrix.

SABER blocks

The B matrix is generally modeled as a series of linear operators, represented in SABER by “SABER blocks”. Such blocks, even if they come from different SABER components of SABER, are interoperable.

SABER testing

SABER has its own pseudo-model for testing purposes, called QUENCH.

A low-level description of the classes, functions, and subroutines is also available, produced by means of the Doxygen document generator.
