When viewing results from an air dispersion model run, the primary concern of many modelers are conditions measured at receptors located in areas generally accessible by the public. This may preclude modeling from occurring within well-defined property boundaries that restrict public access to a facility.
Most air dispersion modeling analyses will result in a large number of data files. Besides input and output files, projects can contain meteorological data, terrain data, digital base maps, and other external data files. Whether you’re modeling a simple scenario in AERMOD or a complex regional study in CALPUFF, there will be many different file types to account for.
When using CALPUFF, modelers can add hourly background concentration or deposition flux values to the modeled results before averages are processed in CALPOST. Lakes Environmental added a Background Data File Maker utility to CALPUFF View to make this process even easier.
