3d-LIIVID provides 2d, 3d, and isosurface radar loops.  The 2d radar provides a base reflectivity return which is taken at a radar tilt angle of .5 degrees above the horizon.  This is what many typical radars display.  The 3d radar provides a reflectivity scan from the base elevation, but it displays it at the actual elevation above the horizon as opposed to locking it to the ground like the 2d radar.  The isosurface scan is the heart of the 3d-LIIVID product.  The isosurface scan is used to render an image which displays volume and density creating a vivid three dimensional view of storm structure.   Understanding the basics of how a radar station works will greatly improve the ability to understand the 3d-LIIVID product. Due to the tilt angle of the radar scan and altitude isosurface and 3d views appear to be displaced from the base map. The further the storms are from the radar station the more amplified this effect is.  Using the traditional 2d radar in conjunction with the isosurface and 3d radars can help maintain perspective on where storms are.  Learn more from NOAA about how radar stations operate.
