GR2Analyst is an advanced Nexrad Level II analysis application. It features a high quality volumetric display and several high resolution reflectivity-derived graphical products in addition to the standard Level II data products.
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.
Using the Volume Renderer
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):
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.
GR2Analyst 1.0 is available for a 21 day trial period. The trial version is fully functional. Click on the link below to install it on your computer.
GR2Analyst Setup (8.5MB)
Your graphics hardware must support Shader Model 2.0. GR2Analyst will not run without that support. See below for more system requirements information.
GR2Analyst has two basic license types: individual/non-profit and commercial. Individual licenses are for personal and other non-commercial users (universities, county EMAs, NOAA, military, etc.). Commercial licenses are for companies (e.g. TV station weather labs, storm chasing companies, forensic meteorologists, etc.).
Please evaluate GR2Analyst with the 21 day free trial before purchasing as there are no refunds once a purchase is made.
Note: If you intend to use GR2Analyst for TV station operations, please contact email@example.com for full details before purchasing. GR2Analyst is only available as a non-exclusive license. GR2Analyst is not available for purchase by TV stations in the following markets:
GR2Analyst supports dual polarization radars and Sigmet's IRIS formatted data files with an additional license.
You must purchase and enter a regular GR2Analyst Individual or Commercial registration key before you will be allowed to enter a Dual Pol/IRIS registration key.
Note: all GRS applications are distributed electronically. There is no boxed product. You must allow email from fastspring.com and grlevelx.com through in order to purchase, register, and sign up on the Owner forums. GRS is not responsible for lost electronic key delivery due to "spam blockers" or other email interference applications. GRS will not make special efforts to communicate with you should a "blocked" reply come your email host.
Note: you must run with administrator privileges in order to enter your registration key(s).
GR2Analyst has significant system requirements:
With the exception of the volume renderer, most shader model 2.0 video cards will be sufficient to run GR2Analyst. The volume renderer is both CPU and GPU intensive. Recommended requirements for the volume renderer:
