The National Weather Service NWS, Federal Aviation Administration FAA, and Department of Defense are in the process of fielding the Next Generation Weather Radars NEXRAD. These doppler weather radars, also known as Weather Surveillance Radar WSR88D, will be replacing the WSR-57 and WSR-74 weather radars in use today. The NEXRAD data will be used by the FAAs Advanced Automation System AAS in place of the Air Route Surveillance Radar ARSR weather data currently being used by air traffic controllers. Because the NEXRADs scanning strategy is more time consuming than the ARSRs, there have been some concerns expressed within the FAA about using untimely NEXRAD data in an Air Traffic Control ATC environment. In response to these concerns, the FAAs Center For Advanced Aviation System Development CAASD at MITRE conducted a study, under the sponsorship of the FAAs National Airspace System NAS system Engineering Service ASE, to assess the relative ability of NEXRADs and ARSRs to detect and present significant weather in order to determine the operational impact of using NEXRAD data in lieu of ARSR data. This paper documents the NEXRADARSR operational comparison study. NEXRAD, TDWR, ASR-9, WSR-88D, Radar, Weather, Surveillance, Reflectivity, Air traffic control.
