Abstract. Online coupled mesoscale meteorology atmospheric chemistry models have undergone a rapid evolution in recent years. Although mainly developed by the air quality modelling community, these are also of interest for numerical weather prediction and regional climate as they can consider not only effects on quality, but potentially important composition weather. Two ways online coupling be distinguished: integrated access coupling. simulate over same grid one model using main time step...
Abstract. We discuss the capability of current state-of-the-art chemistry and transport models to reproduce air quality trends interannual variability. Documenting these strengths weaknesses on basis historical simulations is essential before are used investigate future projections. To achieve this, a coordinated modelling exercise was performed in framework CityZEN European Project. It involved six regional global chemistry-transport (BOLCHEM, CHIMERE, EMEP, EURAD, OSLOCTM2 MOZART)...
Abstract. We present a comparison of tropospheric NO2 from OMI measurements to the median an ensemble Regional Air Quality (RAQ) models, and intercomparison contributing RAQ models two global for period July 2008–June 2009 over Europe. The model forecasts were produced routinely on daily basis in context European GEMS ("Global regional Earth-system (atmosphere) Monitoring using Satellite in-situ data") project. vertical column shows spatial distribution which agrees well with observations,...
Abstract. In order to explore future air quality in Europe at the 2030 horizon, two emission scenarios developed framework of Global Energy Assessment including varying assumptions on climate and energy access policies are investigated with an ensemble six regional global atmospheric chemistry transport models. A specific focus is given paper assessment uncertainties robustness projected changes quality. The present work relies models giving insight into model spread. Both scale were...
Abstract. Systematic measurements of dust concentration profiles at a continental scale were recently made possible by the development synergistic retrieval algorithms using combined lidar and sun photometer data establishment robust remote-sensing networks in framework Aerosols, Clouds, Trace gases Research InfraStructure Network (ACTRIS)/European Aerosol Lidar (EARLINET). We present methodology for these capabilities as tool examining performance transport models. The includes...
Abstract. A detailed 3-D evaluation of an ensemble five regional Chemistry Transport Models (RCTM) and one global CTM with focus on free tropospheric ozone over Europe is presented. It performed a summer period (June to August 2008) in the context GEMS-RAQ project. data set about 400 vertical profiles from balloon soundings commercial aircraft at 11 different locations used for model evaluation, addition satellite measurements infrared nadir sounder (IASI) showing largest sensitivity ozone....
Fourth-order moments of vertical velocity in the convective boundary layer (CBL) are seldom available because unsteady nature atmospheric flows makes time statistics unreliable for evaluation high-order moments. In this paper, sound detection and ranging (sodar) measurements well-developed, almost steady conditions selected analyzed to investigate relationship between skewness kurtosis. Moments up fourth order computed with special attention assessment errors connected number independent...
Abstract. The simulation of the coupled evolution atmospheric dynamics, pollutant transport, chemical reactions and composition is one most challenging tasks in environmental modelling, climate change studies, weather forecasting for next decades as they all involve strongly integrated processes. Weather influences air quality (AQ) transport hazardous materials, while can influence both by directly modifying radiation budget or indirectly affecting cloud formation. Until recently, however,...
A preliminary analysis of boundary layer data acquired during the Arctic Radiation and Turbulence Interaction Study Experiment (ARTIST) at Ny-Ålesund (Spitzbergen) in 1998 is presented. As expected, wind fi eld thermal structure are strongly infl uenced by katabatic fl ow blowing along Kongsfjorden. In particular, if large scale circulation has a component same direction, resulting low level reaches velocities comparable with geostrophic wind. Stable to neutral conditions occurred most time,...

The properties of mesoscale Lagrangian turbulence in the Adriatic Sea are studied from a drifter data set spanning 1990-1999, focusing on role inhomogeneity and nonstationarity. A preliminary study is performed dependence turbulent velocity statistics bin averaging, preferential scale 0.25 chosen. Comparison with independent estimates obtained using an optimized spline technique confirms this choice. Three main regions identified where approximately homogeneous: two boundary currents, West...
In this short review it is suggested that the relationship between third- and fourth-order moments of turbulence in atmospheric boundary layer depends on stability. This can explain some differences among datasets, provides a key point for modelling improvement.

Abstract. The interaction between air quality and climate involves dynamical scales that cover a very wide range. Bridging these in numerical simulations is fundamental studies devoted to megacity/hot-spot impacts on larger scales.
