The authors wish to thank the AQMEII initiative for its tools for post-processing and evaluating data, the WOUDC community for making their ozonesondes data available, the free use of tropospheric NO 2 column data from the YYY sensor at www.temis.nl and the MOPITT CO data obtained from the NASA Langley Research Center Atmospheric Science Data Center. The authors would also like to acknowledge Francesc Martínez for technical support and two anonymous referees for the fruitful comments on the manuscript. This work is funded by grants CGL2010-19652 , Supercomputación and e-ciencia Project (CSD2007-0050) from the Consolider-Ingenio 2010 program of the Spanish Ministry of Economy and Competitiveness . Further support was provided by the SEV-2011-00067 grant of the Severo Ochoa Program, awarded by the Spanish Government . All the numerical simulations were performed with the MareNostrum Supercomputer hosted by the Barcelona Supercomputing Center.

N2 - The Air Quality Model Evaluation International Initiative Phase2 aims to intercompare online coupled regional-scale models over North America and Europe. The NMMB/BSC Chemical Transport Model (NMMB/BSC-CTM) is a fully online integrated system for meso- to global-scale applications under development at the Barcelona Supercomputing Center. The NMMB/BSC-CTM is applied to Europe for the year 2010 in the framework of the AQMEII-Phase2 intercomparison exercise. This paper presents a spatial, temporal and vertical evaluation of the gas-phase model results. This is the first time that the model has been evaluated on a regional scale over a whole annual cycle. The model is compared with available ground-based monitoring stations for relevant reactive gases, ozonesondes, and OMI and MOPITT satellite retrievals of NO2 and CO. A comparative analysis of the present results and several European model evaluations is also presented here. The seasonal cycle for O3, NO2, SO2 and CO is successfully reproduced by the model. The O3 daily mean and daily maximum correlations for the analysed period are r = 0.68 and r = 0.75, respectively. The OMI tropospheric NO2 column retrievals are well reproduced, capturing the most polluted areas over Europe throughout the whole year. Modelled SO2 and CO surface concentrations are generally underestimated, especially during the winter months. Two different vertical configurations of the model (24 and 48 vertical layers) are also analysed. Although model results are very similar, the simulation configured with 48 vertical layers provides better results regarding surface O3 concentrations during summer. Compared to previous model evaluations, the NMMB/BSC-CTM's performance corresponds to state-of-the-art regional air quality models.
