Limited effect of urban tree vegetation on NO2 and O3 concentrations near a traffic route
Concentrations of NO2 and O3 were measured inside and outside a dense broad-leaved forest canopy adjacent to a busy traffic route in the City of Gothenburg, Sweden, with duplicate passive diffusion samplers during six one-week periods starting well before leaf senescence and ending when leaves were largely senescent. Concentrations of NO2 were lower inside the forest canopy during all periods (rep
