pyart.retrieve.quasi_vertical_profile(radar, desired_angle=None, fields=None, gatefilter=None, verbose=False)[source]#

Quasi Vertical Profile.

Creates a QVP object containing fields from a radar object that can be used to plot and produce the quasi vertical profile

  • radar (Radar) – Radar object used.

  • field (string) – Radar field to use for QVP calculation.

  • desired_angle (float) – Radar tilt angle to use for indexing radar field data. None will result in wanted_angle = 20.0

  • verbose (bool) – boolean flag to turn the printing of radar tilts on or off.

Other Parameters:

gatefilter (GateFilter) – A GateFilter indicating radar gates that should be excluded from the import qvp calculation


qvp (Dictonary) – A quasai vertical profile object containing fields from a radar object
