Appendix C National Research Council's Statement of Task for the Pane! on the Adequacy of NEXRAD Based on tasking from the Department of Commerce to the National Academy of Sciences/National Academy of Engineering, the National Weather Service Modernization Committee's Pane! on the Next Generation Radar (NEXRAD) of the National Research Council will: Examine and assess the adequacy of NEXRAD coverage for the nation from the scientific and technical standpoint, in terms of the "no degradation of service" requirement of the Weather Service Modernization Act, October 1992. As defined by section 702 (4) of Public Law 102-567, "degradation of service means any decrease in or failure to maintain the quality and type of weather services provided by the National Weather Service to the public in a service area, including but not limited to a reduction in existing weather radar coverage at an elevation of 10,000 feet." Subtasks: A. Review the specifications of the NEXRAD and NEXRAD network coverage. B. Examine the performance of the operational NEXRADs in relation to their coverage and their ability to detect significant weather. C. Establish criteria for evaluating the adequacy of coverage of He pre-NEXRAD and the proposed NEXRAD network and areas for decommissioning of existing radars. D. Examine and evaluate the adequacy of coverage of the pre-NEXRAD network and the proposed NEXRAD network. The findings and recommendations will be provided in a report targeted at the leadership of NWS, NOAA. and DOC, as well as at Congress and others. 95
