1. Study on gaps in NEXRAD coverage and requirement for plan to address such gaps (a) Study on gaps in NEXRAD coverage (1) In general Not later than 90 days after the date of the enactment of this Act, the Secretary of Commerce shall complete a study on gaps in the coverage of the Next Generation Weather Radar of the National Weather Service (referred to in this section as NEXRAD ). (2) Elements In conducting the study required under paragraph (1), the Secretary shall— (A) identify areas in the United States with limited or no NEXRAD coverage below 6,000 feet above ground level of the surrounding terrain; (B) for the areas identified under subparagraph (A)— (i) identify the key weather effects for which prediction would improve with improved radar detection; (ii) identify additional sources of observations for high impact weather that were available and operational for such areas on the day before the date of the enactment of this Act, including Terminal Doppler Weather Radar (commonly known as TDWR ), air surveillance radars of the Federal Aviation Administration, and cooperative network observers; and (iii) assess the feasibility and advisability of efforts to integrate and upgrade Federal radar capabilities that are not owned or controlled by the National Oceanic and Atmospheric Administration, including radar capabilities of the Federal Aviation Administration and the Department of Defense; (C) assess the feasibility and advisability of incorporating State-operated and other non-Federal radars into the operations of the National Weather Service; (D) identify options to improve radar coverage in the areas identified under subparagraph (A); and (E) estimate the cost of, and develop a timeline for, carrying out each of the options identified under subparagraph (D).
