On adaptive mesh refinement for atmospheric pollution models

Abstract

This paper discusses an implementation of an adaptive resolution system for modeling regional air pollution based on the chemical transport model STEM. The grid adaptivity is implemented using the generic tool Paramesh. The computational algorithm uses a decomposition of the domain, with the solution in different sub-domains computed at different spatial resolutions. We analyze the parallel computational performance versus the accuracy of long time simulations. © Springer-Verlag Berlin Heidelberg 2005.
