pyart.graph.RadarMapDisplay#

class pyart.graph.RadarMapDisplay(radar, shift=(0.0, 0.0), grid_projection=None)[source]#

A display object for creating plots on a geographic map from data in a Radar object.

This class is still a work in progress. Some functionality may not work correctly. Please report any problems to the Py-ART GitHub Issue Tracker.

Parameters:

  • radar (Radar) – Radar object to use for creating plots.

  • shift ((float, float)) – Shifts in km to offset the calculated x and y locations.

Variables:

  • plots (list) – List of plots created.

  • plot_vars (list) – List of fields plotted, order matches plot list.

  • cbs (list) – List of colorbars created.

  • origin (str) – ‘Origin’ or ‘Radar’.

  • shift ((float, float)) – Shift in meters.

  • loc ((float, float)) – Latitude and Longitude of radar in degrees.

  • fields (dict) – Radar fields.

  • scan_type (str) – Scan type.

  • ranges (array) – Gate ranges in meters.

  • azimuths (array) – Azimuth angle in degrees.

  • elevations (array) – Elevations in degrees.

  • fixed_angle (array) – Scan angle in degrees.

  • grid_projection (cartopy.crs) – AzimuthalEquidistant cartopy projection centered on radar. Used to transform points into map projection.
