An ensemble of perturbed analyses to approximate the analysis error covariance in 4dvar

The analysis error covariance is not readily available from four-dimensional variational (4dvar) data assimilation methods, not because of the complexity of mathematical derivation, but rather its computational expense. A number of techniques have been explored for more readily obtaining the analysi...
