Treatment of Some Classes of PDEs and ODEs Part A: Complex Numerical Atmospheric Environmental Models - Overall Description and Applications

Pp. 3-28 (26)

Adolf Ebel and Michael Memmesheimer

Abstract

An overview is presented regarding the development, structure and problems of applications of complex numerical atmospheric environmental models. Different model types based on the mass balance equation for minor reactive atmospheric constituents are briefly described. General aspects of process treatment in aerosol chemistry transport models are addressed. They include chemical mechanisms, particle dynamics and chemistry, emission of anthropogenic and natural compounds and wet and dry deposition. The role of the atmospheric boundary layer is highlighted.

Keywords:

Chemistry transport model, anthropogenic emission, volatile organic compounds (VOC), deposition, aerosol, particle size spectra, atmospheric chemical data assimilation, evaluation of models, climate change, human health.
