CALPUFF Training Presented by TRC


CALPUFF is a non-steady-state modeling system, developed by TRC scientists, that is being used for a wide variety of air quality modeling studies, including toxic pollutant deposition, near-field impacts from point, line, area, and volume sources, forest fire impacts, visibility assessments, and long range transport studies. This system is a comprehensive modeling tool that includes meteorological and geophysical data processors, a meteorological model, a puff-based dispersion model, and postprocessing modules.

TRC is pleased to offer an intensive three day training course that includes hands-on application of the models and provides an introduction to their technical basis. Attendees of the course will receive a training workbook that includes example applications, updates on recent model enhancements, and the latest versions of the models and Graphical User Interfaces (GUIs).
