AbstractAbstract
[en] After an introduction of issues related to a scale change in the field of air quality (existing scales for emissions, transport, turbulence and loss processes, hierarchy of data and models, methods of scale change), the author first presents Gaussian models which have been implemented within the Polyphemus modelling platform. These models are assessed by comparison with experimental observations and with other commonly used Gaussian models. The second part reports the coupling of the puff-based Gaussian model with the Eulerian Polair3D model for the sub-mesh processing of point sources. This coupling is assessed at the continental scale for a passive tracer, and at the regional scale for photochemistry. Different statistical methods are assessed
