GR2Analyst Version 3 is an advanced NEXRAD Level II analysis application. Key features of GR2Analyst 3 are:
GR2Analyst's user defined products feature allows users to create their own derived products like GR2Analyst's own built-in derived products. For example, the image below shows the evolution of max ZDR above the -10°C level prior to tornado formation for KFWS on 2019/10/21 from 0044z to 0202z using the new Max Value Trail support:
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, spectrum width, and KDP):

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.
Using the Volume Renderer
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):
High Resolution Echo Tops
In Live mode, each derived product updates as new tilts are received, keeping you informed even in rapidly changing severe weather events.
