Displays of Level II isosurfaces are controlled by the Isosurface controls. The Radar Isosurface display type allows you to visualize radar data in the 3D, including all elevation angles, at specific data values. An example of when this display type can be useful is if you are looking for only very high reflectivity values that may coincide with a hail spike. WSR-88D Level II Radar data has three moments or data types: Reflectivity, Radial Velocity, and Spectrum Width, indicated by the icon in the Field Selector. WSR-88D Dual Pole radar includes these three moments, as well as DifferentialReflectivity, CorrelationCoefficient, and Differential Phase. In order for Radar Isosurface to be listed as a valid Display Type in the Field Selector, one of the moments (ex. Reflectivity, RadialVelocity, etc.) must be chosen in the Fields panel, not one of their individual elevation angles.
Many of the menu items seen utilizing this display are standard options that can be found in the Menus section of the Layer Controls page. However, there is one option that is unique to this display.
The View menu has this unique option:
