Ticket #962 – Description
initial v1 1 GitHub Pull Request: https://github.com/myroms/roms/pull/25 2 1 3 In 4D-Var, the background (prior) error covariance, **B**, is a large matrix that cannot be computed or stored directly. Still, its effects can be modeled using spatial correlations, **C**, and spatial convolutions via diffusion operators. To convert correlations into error covariance, we multiply by a diagonal matrix of the background error standard deviations, **S**. Hence, 2 4
