Overview
GRLevel2 is a Windows viewer for live and archived NEXRAD Level II data (volumetric reflectivity and velocity data). Base reflectivity, base velocity, storm relative velocity, and spectrum width sweeps for all radar tilts can be ingested. The display has high speed zooming and panning to allow the user a quickly focus on the area of interest.
GRLevel2 Analyst Edition is an advanced NEXRAD Level II analysis application to produce a high quality volumetric display and several high resolution reflectivity-derived graphical products in addition to the standard Level II data products.
GRLevel3 is a Windows viewer for live NEXRAD Level III data from the NWS Radar Product Central Collection Dissemination Service (already produced 2D images). Many television meteorologists, storm chasers, and weather enthusiasts use this software to locate supercells, tornadoes, rain, and other weather phenomenon.
Gibson also wrote GREarth, which overlays satellite and other data and, like the GRLevelX radar viewers, is customizable with GIS layers.
