Efficient estimation of time-mean states of ocean models using 4D-Var and implicit time-stepping
Efficient estimation time-mean states ocean models 4D-Var implicit time-stepping
2009/11/3
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 ...
