Definitions In this title: (1) Administrator The term Administrator means the Administrator of the National Oceanic and Atmospheric Administration. (2) Artificial intelligence weather model The term artificial intelligence weather model means a weather model based primarily on artificial intelligence technology to project future Earth system conditions based on machine learning from an Earth system reanalysis dataset. (3) Earth system reanalysis dataset The term Earth system reanalysis dataset means a dataset that contains continuous global observational data and synthetic data for Earth system variables relevant to weather forecasting. (4) Environmental Information Services Working Group The term Environmental Information Services Working Group means the Environmental Information Services Working Group established under section 401 of the Weather Research and Forecasting Innovation Act of 2017 ( 15 U.S.C. 8541 ), or any similar successor working group. (5) Numerical weather model The term numerical weather model means a weather model based primarily on atmospheric physics and that uses numerical computation to forecast future Earth system conditions. (6) Observational data The term observational data means data from actual observations of environmental conditions. (7) Reforecast analysis The term reforecast analysis means the assessment of a numerical weather model or artificial intelligence weather model by comparing model output and observational data over a period of time in the past. (8) Synthetic data The term synthetic data means data produced from a model or statistical method in order to fill gaps in observational data. 102.
