Temporal resolution of meteorological data and photochemical dispersion

Author(s): P. Sahm & N. Moussiopoulos

Abstract:
The temporal resolution of meteorological data may have a considerable influence on model results for the dispersion and transformation of reactive species.

Two dimensional versions of the mesoscale model MEMO and the photochemical dispersion model MARS are used to study the influence of the update interval of the meteorological quantities assuming pollutant dispersion in a thermally induced flow, specifically a sea/land breeze.

Comparison of simulation results achieved at various update intervals reveals that a low update frequency may lead to an overprediction of ozone concentrations, especially in the evening.

This finding is confirmed also by the results of three dimensional applications of MEMO and MARS dealing with the transport and tran...
