Implementation of Lagrangian particle dispersion model for mesoscale and regional air quality studies M. Uliaszy R.A. Pielke" * Department of Atmospheric Science, Colorado State University, Fort Collins, Colorado 80523, USA * Institute of Environmental Engineering, Warsaw University of Technology, Poland ABSTRACT The possible simplifications of the Lagrangian particle dispersion model are ex- amined in order to develop an efficient tool for mesoscale applications. Computer time requirements for different model versions are also presented. INTRODUCTION The goal of the presented research is the development of an efficient modeling tool to perform intensive calculations of air pollution dispersion on mesoscale and regional scales. Lagrangian particle models linked to numerical meteorolog- ical models have recently become a very important tool for studying dispersion [7, 8]. However, despite advances of computer technology, these models are still computationa
