Case 4.3: Lessons Learned
EKF and EnKF both provided satisfactory
estimates of soil moisture.
EKF cheaper (for 1.5D; equivilant to 4
ensembles), but EnKF more accurate for 6
(or more) ensemble members.
EnKF has the potential to include higher
order moments than mean and std dev
(ie. skewness)
EnKF more promising for including horizontal
correlations.
