The Federal Aviation Administration has been concerned for some time about the number of aircraft accidents during terminal flight in which weather has been identified as the cause or a contributing factor. The next generation weather radar (NEXRAD), for which final specifications are being worked out on a multiservice basis, offers the possibility of dedicated and detailed surveillance of hazardous weather in the terminal airspace. This paper outlines considerations for choosing a site for a NEXRAD installation to fulfill this role in an optimum manner. It is shown that the detection of low-level shear without precipitation imposes the most severe constraints on NEXRAD siting. Three general siting areas are considered: 1) within the airport area, 2) within the terminal area, but outside the airport area, and 3) outside the terminal area. When a single NEXRAD radar must cover all hazardous phenomena over the terminal area, siting within the airport area appears to be the best choice. Under certain conditions, a case exists for siting the NEXRAD outside the terminal area.
