The UMIST instrumented light aircraft (Cessna 182) was used during summer 1999 and winter 2000 to make measurements of aerosol and trace gases in the Boundary Layer (BL) and Free Troposphere (FT) both upwind and downwind of the city of Birmingham in the UK. These measurements were made as part of the NERC URGENT/ASURE program PUMA (Pollution of the Urban Midlands Atmosphere). Gradients in the concentrations of fine and accumulation mode aerosol and of the trace gases NO[sub x] and ozone were observed both in the vertical and horizontally across the conurbation. Examples are presented. These, and thermodynamic data have been made available to initialise and validate output from a high spatial resolution meso-scale model (coupled to dispersion and atmospheric chemistry modules) developed elsewhere in PUMA (in order to predict primary and secondary air pollutant concentrations at urban background locations across the West Midlands region of England).
