pyart.util.column_vertical_profile(radar, latitude, longitude, azimuth_spread=3, spatial_spread=3)[source]#

Given the location (in latitude, longitude) of a target, return the rays that correspond to radar column above the target, allowing for user defined range of azimuths and range gates to be included within this extraction.

  • radar (pyart.core.Radar Object) – Py-ART Radar Object from which distance to the target, along with gates above the target, will be calculated.

  • latitude (float, [degrees]) – Latitude, in degrees North, of the target.

  • longitude (float, [degrees]) – Longitude, in degrees East, of the target.

  • azimuth_spread (int) – Number of azimuth angles to include within extraction list

  • spatial_range (int) – Number of range gates to include within the extraction

column (xarray) – Xarray Dataset containing the radar column above the target for the various fields within the radar object.
