Maps of computational domains of the coupled CTM setup for Marseille simulations: (a) nested domains for CMAQ simulations over Europe with horizontal grid resolutions 36 km × 36 km (yellow frame, d01), 12 km × 12 km (white frame, d02), and 4 km × 4 km (black frame, d03); (b) urban domain for EPISODE-CityChem simulations with extent of 22 km × 22 km and grid resolution of 500 m × 500 m (zoom into area indicated by red frame, d04, in figure part (a). Dark blue frame in figure part (b) indicates the extent of the port city area.
