Impact of Grid Resolution on Aerosol Predictions: A Case Study over Italy

Abstract: This study investigates the effect of grid resolution on the particulate matter (PM 10 , PM 2.5 ) mass concentrations and its chemical composition simulated with the AMS-MINNI modelling system. The air pollution was simulated over Italy with grid resolutions of 20 and 4 km, for a whole year. The gridded emissions were produced performing speciation and spacetime disaggregation of aggregated inventory data, using both land use information and anthropogenic activity-based profiles. Often, the fine grid simulatio… Show more

“…Eight state-of-the-art air quality CTMs delivered their results for the EDT experiments: CHIMERE (Mailler et al, 2017;Menut et al, 2013), CMAQ (Byun and Schere, 2006), EMEP MSC-W (Simpson et al, 2012), LOTOS-EUROS (Manders et al, 2017;Schaap et al, 2008), MATCH (Andersson et al, 2015(Andersson et al, , 2007Robertson et al, 1999), MINNI (Mircea, 2016), Polyphemus (Mallet et al, 2007;Sartelet et al, 2012) and WRF-Chem (Grell et al, 2005;Mar et al, 2016). Given the large computational demand of the simulations, only five modeling teams were able to deliver 21 years of continuous air modeled data: CHIMERE, EMEP MSC-W, LOTOS-EUROS, MATCH and MINNI, the results of which are used in this study.…”

“…A set of state-of-the-art air-quality models participating in the EDT exercise is used here: LOTOS-EUROS (Schaap et al, 2008;Manders et al, 2017), EMEP/MSC-W (Simpson et al, 2012), CHIMERE (Mailler et al, 2017), MATCH (Robertson et al, 1999) and MINNI (Mircea et al, 2016 Colette et al, 2017a for further details). For instance, the boundary conditions were defined from a climatology of observational data for most of the experiments of the EDT exercise (including the data used here).…”

“…ME, NI, or FR) where MLRs are able to describe more than 80 % of the variance in CTMs and observations. This could be attributed to the major role of meteorology in summer influencing local photochemistry processes of ozone production, while in spring long-range transport plays a stronger role (Monks, 2000;Tarasova et al, 2007). As it includes the bias, the RMSE reveals more differences among the MLRs when compared to each other (e.g.…”

“…The model was validated for both meteorological parameters and pollutant concentration. For further details on the emission inventories, domains, input data, and model set-up, see [24,54]. In the context of the present paper the pollutant concentrations simulated with the AMS-MINNI model provide continuous, well-spaced and representative air concentrations that are not available from measurements.…”
