GR2Analyst Version 2
GR2Analyst Version 2 is an advanced Nexrad Level II analysis application. Key features of GR2Analyst are:
Volumetric Display
GR2Analyst's volume rendering engine produces high quality semi-transparent and isosurface 3D displays for any of the base Level II data products (reflectivity, velocity, storm relative velocity, and spectrum width):

With this unprecedented visualization capability, you will see storm structures develop and be able to predict when and where severe weather will impact the ground.
High Resolution Derived Products
GR2Analyst derives five 2D products from the Level II volume reflectivity: Echo Tops, VIL, VILD, POSH, and MEHS. All are displayed on a high resolution radial grid (1km x 1° x 230km with 256 data levels):

In Live mode, each derived product updates as new tilts are received, keeping you informed even in rapidly changing severe weather events.
