[en] In this study, we limited our questions to ORNL, discussing their models with almost a dozen staff members from four divisions. We collected some low-level data about the models, and also tried to gain a sense of the philosophy of the modeler, and how each model fit into the larger perspective of ORNL's and the scientific community's efforts. Time and budget prevented us from conducting any larger study, but we have no reason to suppose that conclusions about ORNL's models and modelers could not be extended to the larger scientific community
