TL;DR: In this paper, the authors compared and compared ozone simulations from seven regional air quality models, the Unified EMEP model, CHIMERE, RCG, MATCH, DEHM and TM5, and showed that the ensemble average concentrations almost always exhibit a closer proximity to observations than any of the models.

TL;DR: In this paper, five three-dimensional chemical transport models of different complexity were applied to Central Europe to assess the ability of models to reproduce PM10 concentrations under highly polluted conditions, and the results showed that there is an increasing underestimation of primary and secondary species with increasing observed PM10.

TL;DR: In this article, the authors compared six different models to simulate a full year (1999) of air quality pollutant concentrations over domains encompassing a large area around four major European cities: Berlin, Milan, Paris and Prague.

TL;DR: The CityDelta project as mentioned in this paper was designed to evaluate the impact of emission-reduction strategies on air quality at the European continental scale and in European cities, with particular attention to the differences between large-scale and fine-scale models.

TL;DR: In this article, the authors evaluated the performance of chemistry transport model performances in terms of bias, root mean square error and correlation with respect to the concentrations of air pollutants (NO2, O3, SO2, PM10 and PM2.5), as well as key meteorological variables.
