METplus can perform comparison against gridded datasets using the grid_stat
tool. Enable grid_stat comparisons by adding to your rose-suite.conf:
RUN_METPLUS_GRID_STAT = True
Observations have to be configured for your site so that METplus knows the correct source data paths.
Select which observations to run using e.g.:
METPLUS_GRID_STAT_OBS = ["GPM"]
The workflow creates spatial plots of the model field, observation field and
difference between model and observation. grid_stat handles regridding both
data sources to a common grid.
