Rooftop meteorological data from the BT Tower, London (DAPPLE)
Field
Rooftop meteorological measurements from the BT Tower during the DAPPLE campaign in London, used to reference street-level flows. Useful as reference wind and turbulence data for urban dispersion and emergency-response studies.
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.
Meteorology and air quality field campaign in London in 2011-12, with multiple sites and intensive observations during the 2012 Olympics. Useful for urban boundary-layer and air quality studies; individual datasets are available via the paper authors.
Air pollution field campaigns in London in 2006/7 with measurements at ground level and at 160 m on the BT Tower. Useful for studying pollutant concentrations and transport above and within a megacity.
Time-resolved wind-tunnel velocity data built to validate LES: three approach boundary layers, flow and puff dispersion in a cube array, and the 1:225 idealised Central-European city Michelstadt with flat or slanted roofs.
