In the transition from He old system to the new, Congress and others have expressed concerns about the adequacy of the new radar network to detect significant weather events over vulnerable areas of the contiguous United States such that there will be no degradation of the service currently provided by the NWS.i It is important to note that degradation in any one component of the new system, including NEXRAD coverage, does not necessarily imply a net degradation in the overall system. Congress asked the National Research Council (NRC)

the pane! agreed to receive public comments and "to conduct an independent scientific assessment of Me proposed NEXRAD radar coverage and consolidation of field offices in terms of 'no degradation of services' and to establish criteria for identifying service areas where the decommissioning of existing radars could degrade service." The panel did not explicitly address nontechnical issues, such as economic, safety, and population risk factors, that were beyond the scope of this study.
