Kalman Filters and 3DVaror a closed-form solution that minimizes the cost function, and then we continue discussing how specific cases lead to several well-known methods. The first case assumes that the measurements are all located at the initial time of the assimilation window. Thus, there is no need for any model integra

Localization and Inflationases the effective rank of the ensemble covariance matrix and allows it to fit a large number of independent observations. Thus, we use localization to reduce sampling errors, in combination with inflation, to reduce the underestimation of the ensemble variance caused by the low-rank approximation.

We will also dive deeper into the behavior of the SC-4DVar with highly nonlinear- and
