“…Agricultural emissions are taken into account in only a few models and even in those models, they are crudely calculated and poorly validated. A more detailed description of windblown dust emissions can be found in the report of Schaap et al (2009) and references therein. Apart from uncertainties in parameterisations of wind-blown dust emissions, there is uncertainty in the underlying land use and soil texture maps.…”

“…For any type of emitted primary aerosol, a better physicochemical characterisation in terms of number and mass size distributions, hygroscopicity, and internal versus external mixture, would be desirable as number concentrations and size distribution have a major impact on their cloud forming properties and radiation effects, rather than their mass concentrations. Such inventories are currently being developed (Denier van der Gon et al, 2009). Wind-blown dust emissions from dry soils and resuspension of particles are still poorly understood and described in models.…”

Published by Copernicus Publications on behalf of the European Geosciences Union. A. Baklanov et al.: Online coupled regional meteorology chemistry models in EuropeAbstract. 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 models are also of interest for numerical weather prediction and regional climate modelling as they can consider not only the effects of meteorology on air quality, but also the potentially important effects of atmospheric composition on weather. Two ways of online coupling can be distinguished: online integrated and online access coupling. Online integrated models simulate meteorology and chemistry over the same grid in one model using one main time step for integration. Online access models use independent meteorology and chemistry modules that might even have different grids, but exchange meteorology and chemistry data on a regular and frequent basis. This article offers a comprehensive review of the current research status of online coupled meteorology and atmospheric chemistry modelling within Europe. Eighteen regional online coupled models developed or being used in Europe are described and compared. Topics discussed include a survey of processes relevant to the interactions between atmospheric physics, dynamics and composition; a brief overview of existing online mesoscale models and European model developments; an analysis on how feedback processes are treated in these models; numerical issues associated with coupled models; and several case studies and model performance evaluation methods. Finally, this article highlights selected scientific issues and emerging challenges that require proper consideration to improve the reliability and usability of these models for the three scientific communities: air quality, numerical meteorology modelling (including weather prediction) and climate modelling. This review will be of particular interest to model developers and users in all three fields as it presents a synthesis of scientific progress and provides recommendations for future research directions and priorities in the development, application and evaluation of online coupled models.

“…The participating CTMs in this study are CHIMERE (Schmidt et (Schaap et al, 2008), and RCG (Stern et al, 2003). To represent, as much as possible, the uncertainty 162 in our current knowledge of air quality processes, we allow all models to freely and independently 163 utilize their best estimate for most input data and parameters (e.g., meteorological input, boundary 164 conditions, natural emissions).…”

information, but will cubically increase computational costs and pose additional challenges 35 concerning high resolution input data. The motivation for the present study was therefore to explore 36 the impact of using finer horizontal grid resolution for policy support applications of the European 37 variability. This study clearly shows that increasing model resolution is advantageous, and that 49 leaving a resolution of 50 km in favour of a resolution between 10 and 20 km is practical and 50worthwhile. As about 70% of the model response to grid resolution is determined by the difference 51 in the spatial emission distribution, improved emission allocation procedures at high spatial and 52 temporal resolution are a crucial factor for further model resolution improvements. 53 54

“…There are a number of models that can be applied to each single médium, or to a combination of two. Examples of spatially explicit chemical fate models that can be applied to model large regions for different single (or coupled) environmental media include GREAT-ER (Feijtel et al, 1997), a stochastic simulator based on a plug-flow equation model of rivers, that predicts concentrations of chemicals from wastewater and other sources in inland waters and has been used in the context of water management; SWAT (Neitsch et al, 2002), a model including catchment hydrology, soil processes, stream processes, with the resolution of a subcatchment, used for the simulation of nutrients and pesticides over large domains; and LOTOS-EUROS (Schaap et al, 2008), an atmospheric transport model for continental Europe.…”

Keywords:Spatially explicit fate models GIS Data assimilation Analytical solutions Simplifl catión A review by Hollander et al. (in preparation), discusses the relative potentials, advantages and shortcomings of spatial and non spatial models of chemical fate, highlighting that spatially explicit models may be needed for specific purposes. The present paper revie ws the state of the art in spatially explicit chemical fate and transport modeling in Europe. We summarize the three main approaches currently adopted in spatially explicit modeling, namely (1) múltiple box models, (2) numerical solutions of simultaneous advection-dispersion equations (ADE) in air, soil and water, and (3) the development of meta-models. As all three approaches experience lfmitations, we describe in further detail geographic information system (GlS)-based modeling as an alternative approach allowing a simple, yet spatially explicit description of chemical fate. We review the input data needed, and the options available for their retrieval at the European scale. We also discuss the fmportance of, and lfmitations in model evaluation. We observe that the high uncertainty in chemical emissions and physico-chemical behavior in the environment make realistic simulations difficult to obtain. Therefore we envisage a shift in model use from process simulation to hypothesis testing, in which explaining the discrepancies between observed and computed chemical concentrations in the environment takes fmportance over prediction per se. This shift may take advantage of using simple models in GIS with residual uses of complex models for detailed studies. It also calis for tighter joint interpretation of models and spatially disfributed monitoring datase ts, and more refined spatial representation of environmental drivers such as landscape and climate variables, and better emission estimates. In summary, we conclude that the problem is not "how to compute" (i.e. emphasis on numerical methods, spatial/temporal discretization, quantitative uncertainty and sensitivity analysis...) but "what to compute" (i.e. emphasis on spatial disfribution of emissions, and the depiction of appropriate spatial patterns of environmental drivers).
