pyart.retrieve.create_cappi#
- pyart.retrieve.create_cappi(radar, fields=None, height=2000, gatefilter=None, vel_field='velocity', same_nyquist=True, nyquist_vector_idx=0)[source]#
Create a Constant Altitude Plan Position Indicator (CAPPI) from radar data.
- Parameters:
radar (Radar) – Py-ART Radar object containing the radar data.
fields (list of str, optional) – List of radar fields to be used for creating the CAPPI. If None, all available fields will be used. Default is None.
height (float, optional) – The altitude at which to create the CAPPI. Default is 2000 meters.
gatefilter (GateFilter, optional) – A GateFilter object to apply masking/filtering to the radar data. Default is None.
vel_field (str, optional) – The name of the velocity field to be used for determining the Nyquist velocity. Default is ‘velocity’.
same_nyquist (bool, optional) – Whether to only stack sweeps with the same Nyquist velocity. Default is True.
nyquist_vector_idx (int, optional) – Index for the Nyquist velocity vector if same_nyquist is True. Default is 0.
- Returns:
Radar – A Py-ART Radar object containing the CAPPI at the specified height.
Notes
CAPPI (Constant Altitude Plan Position Indicator) is a radar visualization technique that provides a horizontal view of meteorological data at a fixed altitude. Reference: https://glossary.ametsoc.org/wiki/Cappi
