Block ENSEMBLE_POST

The block is used by the task PosEns for post-processing ensemble runs

  1. POSTPROCESS_MEMBERS = (options)
    • Define if individual member results are included in the output file .ens.nc
    • Input options:
      • YES: Include individual members
      • NO: Exclude individual members
    • Note: The option POSTPROCESS_MEMBERS = YES may result in very large files
  2. POSTPROCESS_MEAN = (options)
    • Postprocess the ensemble mean in the output file *.ens.nc
    • Input options:
      • YES: Include ensemble mean
      • NO: Exclude ensemble mean
  3. POSTPROCESS_LOGMEAN = (options)
    • Postprocess the ensemble (log) mean in the output file *.ens.nc
    • Input options:
      • YES: Include ensemble (log) mean
      • NO: Exclude ensemble (log) mean
  4. POSTPROCESS_MEDIAN = (options)
    • Postprocess the ensemble median in the output file *.ens.nc
    • Input options:
      • YES: Include ensemble median
      • NO: Exclude ensemble median
  5. POSTPROCESS_STANDARD_DEV = (options)
    • Postprocess the ensemble standard deviation in the output file *.ens.nc
    • Input options:
      • YES: Include ensemble standard deviation
      • NO: Exclude ensemble standard deviation
  6. POSTPROCESS_PROBABILITY = (options)
    • Generate probabilistic forecasts based on thresholds (see below) in the output file *.ens.nc. Probabilities are obtained by counting the fraction of ensemble members exceeding a given threshold
    • Input options:
      • YES: Include probabilistic forecasts
      • NO: Exclude probabilistic forecasts
  7. POSTPROCESS_PERCENTILES = (options)
    • Generate percentile forecasts in the output file *.ens.nc
    • Input options:
      • YES: Include percentile forecasts
      • NO: Exclude percentile forecasts

Sub-block IF_POSTPROCESS_PROBABILITY

Used when POSTPROCESS_PROBABILITY = YES

  1. CONCENTRATION_THRESHOLDS_(MG/M3) = (float_list)
    • List of values giving the concentration threshold
    • Note: A probability forecast map is generated for each value
  2. COLUMN_MASS_THRESHOLDS_(G/M2) = (float_list)
    • List of values giving the column mass threshold for species TEPHRA
    • Note: A probability forecast map is generated for each value
  3. COLUMN_MASS_THRESHOLDS_(DU) = (float_list)
    • List of values giving the column mass threshold for species SO2
    • Note: A probability forecast map is generated for each value
  4. GROUND_LOAD_THRESHOLDS_(KG/M2) = (float_list)
    • List of values giving the deposit ground load threshold for species TEPHRA
    • Note: A probability forecast map is generated for each value

Sub-block IF_POSTPROCESS_PERCENTILES

Used when POSTPROCESS_PERCENTILES = YES

  1. PERCENTILE_VALUES_(%) = (float_list)
    • List of values giving the percentiles in percent
    • Note: A percentile forecast map is generated for each value
