The global ensemble calculates the initial condition perturbations using a local version of the ensemble transform kalman filter (etkf). For an ensrf, for instance, the ensemble transform kalman filter (etkf) , , the analysis ensemble is generated by adding perturbations to the ensemble mean. All the da schemes used in this study are based on the framework of the local ensemble transform kalman filter (etkf, ).
