; (B) hurricane track and intensity forecasting; (C) tornado warning lead times and accuracy; (D) prediction of mid-latitude severe local storm outbreaks; and (E) prediction of storms that have the potential to cause extreme precipitation and flooding lasting from 6 hours to 1 week; and (2) shall be conducted in cooperation with other appropriate entities within the National Oceanic and Atmospheric Administration, other Federal agencies, the United States weather industry, and academic partners to ensure the technical and scientific merit of results from Observing System Simulation Experiments or other appropriate quantitative assessment methodologies. (b) Requirements Observing System Simulation Experiments shall quantitatively— (1) determine the potential impact of proposed space-based, suborbital, and in situ observing systems on analyses and forecasts, including potential impacts on extreme weather events across all parts of the Nation; (2) evaluate and compare observing system design options; and (3) assess the relative capabilities and costs of various observing systems and combinations of observing systems in providing data necessary to protect life and property. (c) Implementation Observing System Simulation Experiments— (1) shall be conducted prior to the acquisition of major Government-owned or Government-leased operational observing systems, including polar-orbiting and geostationary satellite systems, with a lifecycle cost of more than $500,000,000
