GRLevelX is a suite of data processing and display programs developed by Gibson Ridge Software, LLC (GRS), to view weather radar data. It went on the market in March 2005. It comes in three versions, all of which ingest raw data: ''GRLevel2'' and ''GRLevel2 Analyst Edition'' for viewing Level II data of the National Weather Service (NWS), and ''GRLevel3'' for viewing Level III data. Both program lines feature high speed, high quality displays with an intuitive (if minimalist) user interface. All programs are capable of rendering dual polarization data. The software allows the user to view real-time data as well as archive data stored locally or obtained over the internet. It is used by professional forecasters and researchers for general precipitation analysis as well as severe storm, tornado, and tropical cyclone monitoring and analysis. Its usage base grew to include many television weathercasters, including by The Weather Channel severe storms expert Greg Forbes, as well as storm chasers, storm spotters, emergency managers, weather enthusiasts, private sector meteorologists, and is often used within the NWS, itself. ''GRLevel2 Analyst Edition'' allows the user to take a 3D images of precipitation within clouds, such as in supercell thunderstorms. It's integrated algorithms flag possible hail, tornado vortex signatures (TVSs), and mesocyclones. All GRx applications are written in multithreaded C++ using the base Windows APIs. Software engineer Michael Scott Gibson wrote the programs.〔(About GRLevelX )〕 == 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). In addition to Level III WSR-88D data, GR3 supports TDWR, which is high resolution shorter range radar located at some major airports. Gibson also wrote ''GREarth'', which overlays satellite and other data and, like the GRLevelX radar viewers, is customizable with GIS layers.〔(GREarth User Guide )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「GRLevelX」の詳細全文を読む スポンサード リンク
