Short summary

This study presents a new version of the multi-scale model Street-in-Grid (SinG) that interconnects regional and local scales in air-quality modeling in urban areas. The new version of SinG performs the finest coupling between transport and chemistry, leading to a numerically stable partitioning between NO and NO₂. Multi-scale, local-scale and regional-scale simulations of NO, NO₂ and NO_x over Paris are compared to observations, and SinG shows good performance for both local and regional scales.
