Discussion
It should be noted here that at the moment the smoothing of the Kalman gain takes place in OpenDA only when the simulation covers the previous analysis time. The results of EnKF-GS shown above are obtained by running the simulation over 1 year splitted into 3 days periods. Hence, no smoothing has actually taken place. The result can be seen simply as another result of the EnKF.
