EPA Models Should Undergo 'Life-Cycle' Evaluation
Print This
June 18 -- Although the computer-model results behind many U.S. Environmental Protection Agency regulations will always be constrained by computational limitations, assumptions, and data gaps, models can be improved through continuous evaluation, says a new National Research Council report. Peer review should be considered at each stage of a model's life, uncertainties should be communicated clearly, and all stakeholders should be ensured access to information about the models, the report adds.
