Plan and implementation of plan to make certain models and data available to the public (a) In general The Administrator shall develop and implement a plan to make available to the public the following: (1) Operational models developed by the Administration. (2) Models that are not operational models, including experimental and developmental models, as the Administrator determines appropriate. (3) Applicable information and documentation for models described in paragraphs (1) and (2). (4) Subject to section 7, all data owned by the Federal Government and data that the Administrator has the legal right to redistribute that are associated with models made available to the public pursuant to the plan and used in operational forecasting by the Administration, including— (A) relevant metadata; (B) data used for operational models used by the Administration as of the date of the enactment of this Act; and (C) a description of intended model outputs.

(e) Platforms In carrying out subsections (a) and (b), the Administrator may use government servers, contracts or agreements with a private vendor, or any other platform consistent with the purpose of this Act. (f) Support program The Administrator shall plan for and establish a program to support infrastructure, including telecommunications and technology infrastructure of the Administration and the platforms described in subsection (e), relevant to making operational models and data available to the public pursuant to the plan under subsection (a). (g) Technical correction Section 102(b) of the Weather Research Forecasting and Innovation Act of 2017 ( 15 U.S.C. 8512(b) ) is amended by redesignating the second paragraph (4) (as added by section 4(a) of the National Integrated Drought Information System Reauthorization Act of 2018 ( Public Law 115–423 ; 132 Stat. 5456)) as paragraph (5). 5. Requirement to review models and leverage innovations The Administrator shall— (1) consistent with the mission of the Earth Prediction Innovation Center, periodically review innovations and improvements made by persons outside the Administration to the operational models made available to the public pursuant to the plan under section 4(a) in order to improve the accuracy and timeliness of forecasts of the Administration; and (2) if the Administrator identifies an innovation for a suitable model, develop and implement a plan to use the innovation to improve the model. 6. Report on implementation (a) In general Not later than 2 years after the date of the enactment of this Act, the Administrator shall submit to the appropriate congressional committees a report on the implementation of this Act that includes a description of— (1) the implementation of the plan required by section 4; (2) the process of the Administration under section 5— (A) for engaging with interested stakeholders to learn what innovations those stakeholders have found; (B) for reviewing those innovations; and (C) for operationalizing innovations to improve suitable models. (b) Appropriate congressional committees defined In this section, the term appropriate congressional committees means— (1) the Committee on Commerce, Science, and Transportation and the Committee on Appropriations of the Senate; and (2) the Committee on Science, Space, and Technology and the Committee on Appropriations of the House of Representatives. 7.
