Field tracer experiments in central London (DAPPLE, 2004)
Field
Tracer release experiments from the 2004 DAPPLE field campaign in central London. Useful for validating urban dispersion models against measured concentrations.
A real-city SF6 field release sampled at 20 detectors, plus wind-tunnel pedestrian-level concentration time series for continuous and puff releases in a model of the same downtown.
Urban Dispersion Program field studies in 2005: two intensive periods around Madison Square Garden (March) and six in Midtown (August) with up to seven perfluorocarbon and SF6 tracers, street-level and rooftop samplers, sonic anemometers and sodars, plus indoor and subway sampling in MID05.
DTRA/DHS field study in July 2003: ten 8-hour intensive periods of SF6 releases in the central business district, sampled by 194 bag samplers and 25 fast-response analysers, with winds and turbulence measured at about 100 sites. A classic real-city dispersion benchmark.
Basel Urban Boundary Layer Experiment, 2001–02: a year-long network of energy-balance towers across urban, suburban and rural sites, with a June–July 2002 intensive period adding a wind profiler, sodar/RASS, lidar, a street-canyon tower and four SF6 tracer releases. A reference for urban roughness-sublayer turbulence and energy balance.
Classic multiscale urban dispersion campaign: SF6 and perfluorocarbon tracer releases with meteorology around a single building, across the downtown grid and over the wider city, mostly in stable night-time conditions. Files are openly downloadable by IOP.
TURDATA from the TURBAN Prague campaign: low-cost air quality sensor network, meteorological station and remote-sensing vertical profiles in the Legerova street domain. Intended for validating micro-scale urban dispersion models.
