    "abstract": "A Lagrangian column model has been developed to simulate the mean (monthly\nand annual) three-dimensional structure in ozone and nitrogen oxides\nconcentrations in the boundary layer within and immediately around an urban\narea. Short time-scale photochemical processes of ozone, as well as emissions\nand deposition to the ground are simulated. The results show that the average\nsurface ozone concentration in the urban area is lower than the surrounding\nrural areas by typically 50%. Model results are compared with observations.",
