(grid, refl_field=None, frz=4500.0)[source]¶ Estimates fall speed based on reflectivity.
Uses methodology of Mike Biggerstaff and Dan Betten
- Parameters
- Grid: Py-ART Grid
Py-ART Grid containing reflectivity to calculate fall speed from
- refl_field: str
String containing name of reflectivity field. None will automatically determine the name.
- frz: float
Height of freezing level in m
- Returns
- 3D float array:
Float array of terminal velocities
