Efficient estimation of time-mean states of ocean models using 4D-Var and implicit time-stepping
We propose an efficient method for estimating a time-mean state of an ocean model subject to given observations using implicit time-stepping. The new method uses (i) an implicit implementation of the 4D-Var method to fit the model trajectory to the observations, and (ii) a pre-processor which applie...
