Abstract: Methods, systems, and articles of manufacture for generating an ensemble of forecasting models are provided herein. A method includes identifying a given environmental event from multiple items of input data; estimating an accuracy value for each of multiple forecasting models applied to an environmental event related to the given environmental event based on historical data; computing a cost and one or more resource requirements for each of the multiple forecasting models; and determining an ensemble of one or more of the multiple forecasting models to apply to the given environmental event based on (i) said estimated accuracy value for each of the multiple forecasting models, and (ii) said cost and said one or more resource requirements for each of the multiple forecasting models.
