Block MODEL_VALIDATION

This block is read by task PosVal to perform automatic model validation with a set of quantitative and categorical metrics

1. OBSERVATIONS_TYPE = (options)
   • Type of observations
   • Input options:
     • SATELLITE_DETECTION: Satellite yes/no flag contours
     • SATELLITE_RETRIEVAL: Satellite quantitative retrievals of TEPHRA/SO2 species
     • DEPOSIT_CONTOURS: Deposit isopach/isopleth contours read from a gridded netCDF file
     • DEPOSIT_POINTS: Deposit point-wise observations
2. OBSERVATIONS_FILE = (string)
   • Path to the files with observations
3. OBSERVATIONS_DICTIONARY_FILE = (string)
   • Path to the observations dictionary file
   • Optional
   • Note: Examples can be found in Other/Dep
4. RESULTS_FILE = (string)
   • Path to the FALL3D output file with simulation results (*.res.nc or *.ens.nc)

Sub-block IF_OBSERVATIONS_TYPE_SATELLITE

Used when OBSERVATIONS_TYPE = SATELLITE_DETECTION or OBSERVATIONS_TYPE = SATELLITE_RETRIEVAL

1. COLUMN_MASS_OBSERVATION_THRESHOLD_(G/M2) = (float)
   • Column mass threshold in g/m2 for TEPHRA species
   • Note: It should be consistent with COLUMN_MASS_THRESHOLDS_(G/M2) for ensemble runs
2. COLUMN_MASS_OBSERVATION_THRESHOLD_(DU) = (float)
   • Column mass threshold in DU for SO2 species
   • Note: It should be consistent with COLUMN_MASS_THRESHOLDS_(DU) for ensemble runs

Sub-block IF_OBSERVATIONS_TYPE_DEPOSIT

Used when OBSERVATIONS_TYPE = DEPOSIT_CONTOURS or OBSERVATIONS_TYPE = DEPOSIT_POINTS

1. GROUND_LOAD_OBSERVATION_THRESHOLD_(KG/M2) = (float)
   • Deposit load threshold in kg/m2 for TEPHRA species
   • Note: It should be consistent with GROUND_LOAD_THRESHOLDS_(KG/M2) for ensemble runs
