Abstract

An important new emphasis in meteorological models evaluation is the thorough discussion of vertical profiles of meteorological parameters. This discussion contributes to the understanding of why different mesometeorological models calculate quite different wind and temperature profiles and atmospheric boundary layer heights (even when using the same method) while all show good agreement between simulated and measured surface data. The wind, temperature and turbulence profiles influence significantly the transport and diffusion of pollutants in the air. The calculations of a number of crucial parameters in air quality models, such as deposition and biogenic emissions, also depend on meteorological parameters. The availability of 3D measured wind fields provided by wind profile radars and lidars give a new challenge for such studies. The 3D model to measurements comparisons should consider new performance statistics. This study presents few examples from the COST 728 intercomparison exercise for the winter of 2003 in Europe.
