Table 4 Thresholds of cell segment search
Threshold | Meaning | Default value |
|---|---|---|
Reflectivity(dBZ) | A set of minimum effective reflectivity which the reflectivity factor of a sample volume must meet or exceed to be included in a cell segment | 25, 30, 35, 40, 45, 50, 55 |
Dropout reflectivity difference (dBZ) | The difference below threshold (reflectivity) in effective reflectivity that a sample volume may still be included in a cell segment | 5 |
Dropout count(unit) | The maximum number of contiguous sample volumes with a reflectivity factor less than the threshold (reflectivity) by less than or equal to the threshold (dropout reflectivity difference) that may be included in a cell segment | 2 |
Segment length (km) | Set of minimum lengths of a component for each reflectivity threshold | 1 |
