Model inter-comparison study between NMMB/BSC-CTM and Enviro-HIRLAM on-line systems contributing to the AQMEII-phase2 initiative

Abstract

The Air Quality Model Evaluation International Initiative (AQMEII) Phase-2 aims to inter-compare on-line couple regional-scale models over North America and Europe. Common chemical boundary conditions, emissions, and domain configurations are pre-defined. In this study, we present the 2010 annual modelling results from two on-line integrated models, NMMB/BSC-CTM and Enviro-HIRLAM, as a contribution to the European domain simulations of AQMEII-Phase2 initiative and COST Action ES1004 EuMetChem. Both models have been configured according to requirements of AQMEII-Phase2 initiative. Model results will be evaluated against ground-based monitoring stations and vertical profiles. The performance and capability of both systems to reproduce surface and vertical structure of relevant reactive gases and aerosols will be discussed.
