1 The Air Pollution Model (TAPM) Version 1: Technical Description and Examples

Air pollution predictions for environmental impact assessments usually use Gaussian plume/puff models driven by observationally-based meteorological inputs. An alternative approach is to use prognostic meteorological and air pollution models, which have many advantages over the Gaussian approach and are now becoming a viable tool for performing year-long simulations. Continuing rapid increases in computing power are bringing this approach within reach of a desktop PC. This report provides a comprehensive technical description of a newly developed prognostic model called The Air Pollution Model (TAPM), and provides two example simulations which illustrate model performance.
