Parameter estimation

Some calibrators provide a mechanism for training the coefficients in the method by using a set of training forecasts and training observations. The “gridpp_train” program is used for this.

gridpp_train <obs_files> type=netcdf <fcst_files> type=netcdf -p netcdf file=parameters.nc

It is important that you specify the same calibrator options when training as when applying, since the parameters will be specifically computed using those options.
