Modelling static 3-D spatial background error covariances – the effect of vertical and horizontal transform order

A major difference in the formulation of the univariate part of static background error covariance models for use in global operational 4DVAR arises from the order in which the horizontal and vertical transforms are applied. This is because the atmosphere is non-separable with large horizontal scale...
