4.3.2 Level II RHI Displays

The IDV makes a pseudo-RHI display from Level II data. The display is presented in a conventional 2D plot, and in a 3D display at the correct position in the atmosphere.

The pseudo-RHI display is constructed from the several azimuthal sweeps available in the WSR-88D Level II output files.

If necessary, select Level II data and times as described in Accessing WSR-88D Level II Radar Data.

  1. If other displays are in the main IDV window, select the Edit->Remove All Displays menu item or the icon in the toolbar to clear them out.
  2. In the Field Selector window create a RHI display using the Reflectivity field.
  3. The RHI control window appears in the Dashboard. The RHI display appears inside the RHI control window as a 2D plot.
