+case_id: Save JSON and figure files into this subdirectory so that results from multiple tests can be readily organized.
+test_data_set: List of model names.
+realization: List of realizations or “*” to use all realizations.
+test_data_path: File path to directory containing model/test data.
+filename_template: File name template for test data, e.g., “%(variable)_SImon_%(model_version)_historical_r1i2p2f1_gr_201001-201112.nc” where “model_version” and “variable” will be analyzed for each of the entries in test_data_set and vars.
+var: Name of model sea ice variable
+msyear: Start year for test data set.
+meyear: End year for test data set.
+ModUnitsAdjust: Factor to convert model sea ice data to fraction of 1. Uses format (flag (bool), operation (str), value (float)). Operation can be “add”, “subtract”, “multiply”, or “divide”. For example, use (True, ‘multiply’, 1e-2) to convert from percent concentration to decimal concentration.
+area_template: File path of model grid area data.
+area_var: Name of model area variable, e.g. “areacello”
+AreaUnitsAdjust: Factor to convert model area data to units of km 2 . Uses format (flag (bool), operation (str), value (float)). Operation can be “add”, “subtract”, “multiply”, or “divide”. For example, use (True, ‘multiply’, 1e-6) to convert from m 2 to km 2 .
+metrics_output_path: Directory path for metrics output in JSON files, e.g., ‘~/demo_data/PMP_metrics/’. The %(case_id) variable can be used here. If exists, should be empty before run.
+reference_data_path_nh: The reference data file path for the northern hemisphere. If data is global, provide same path for nh and sh.
+reference_data_path_sh: The reference data file path for the southern hemisphere. If data is global, provide same path for nh and sh.
+ObsUnitsAdjust: Factor to convert reference sea ice data to fraction of 1. Uses format (flag (bool), operation (str), value (float)). Operation can be “add”, “subtract”, “multiply”, or “divide”. For example, use (True, ‘multiply’, 1e-2) to convert from percent concentration to decimal concentration.
+reference_data_set: A short name describing the reference dataset, e.g. “OSI-SAF”.
+osyear: Start year for reference data set.
+oeyear: End year for reference data set.
+obs_var: Name of reference sea ice variable.
+ObsAreaUnitsAdjust: Factor to convert model area data to units of km 2 . Uses format (flag (bool), operation (str), value (float)). Operation can be “add”, “subtract”, “multiply”, or “divide”. For example, use (True, ‘multiply’, 1e-6) to convert from m 2 to km 2 .
+obs_area_template: File path of grid area data. If unavailalbe, skip and use “obs_cell_area”.
+obs_area_var: Name of reference area variable, if available. If unavailable, skip and use “obs_cell_area”.
+obs_cell_area: For equal area grids, the area of a single grid cell in units of km 2 . Only required if obs area file is not available.
+pole: Set the maximum latitude for the Central Arctic and Arctic regions to exclude ice over the pole. Default is 90.1 to include all ice.
