Title 15 › CHAPTER 111 — WEATHER RESEARCH AND FORECASTING INNOVATION › SUBCHAPTER I — UNITED STATES WEATHER RESEARCH AND FORECASTING IMPROVEMENT › § 8512a
NOAA must make its operational weather and Earth-system models, plus other models it chooses, available to the public for free under an open license. The release must include documentation, relevant metadata, and government-owned data used in forecasts, including data used by NOAA as of December 23, 2022. The agency must prioritize operational models, can exclude models expected to be retired or replaced within five years after December 23, 2022, and may limit releases to protect national security, intellectual property, trade secrets, contract rules, privacy, or its mission. NOAA can host the materials on government servers or private platforms and must plan for the infrastructure needed to do this. Definitions in one line each: Administration = NOAA; Administrator = the NOAA Under Secretary and agency head; Earth Prediction Innovation Center = the community global weather research modeling system; Model = a vetted numerical Earth-system model developed by NOAA or with federal funds; Operational model = a model NOAA uses for operations; Open license = as defined in title 44; Suitable model = a model meeting the law’s listed requirements. NOAA must review outside improvements to shared operational models and adopt useful innovations into suitable models. The Administrator must report to the specified congressional committees within 2 years after December 23, 2022 about how the plan and review process work and how federal funds were used to encourage outside contributions. The law authorizes $2,000,000 per year for fiscal years 2023 through 2027. The Administrator, after consulting with the Secretary of Defense when appropriate, may withhold any model or data tied to the Department of Defense if needed for national security.
