How to run a forward simulation using the results of an inversion

After running an inversion, it may be useful, e.g. for evaluating the results, to run a forward simulation using the results of the inversion as inputs.

This is simply done from the yaml used for the inversion by:

• changing the WORKDIR

• changing the mode to forward (and, for clarity’s sake, remove the arguments which are only useful for the inversion such as the minimizer). Add the optional argumemnt use_xb: False so that the output fiels are NOT created using the prior state.

• in controlvect, add optional arguments reload_xb: True and reload_file to provide the path to the pickle file where the controlvects are stored. It probably is $WORKDIR_inversion/controlvect_final.pickle.

• change the components of the datavect which are not to be the same as in the inversion e.g. concs or satellites for comparing to other data than the assimilated ones.
