One of the world's longest urban flux records (tower running since 2004, successor to the BUBBLE experiment): half-hourly CO2, heat and momentum fluxes, friction velocity and stability with footprints for 2015–2025.
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.
Météo-France/CNRM campaign from February 2004 to February 2005: a city-centre flux tower and surface stations, boundary-layer profilers and intensive periods on the urban heat island, the urban boundary layer and aerosols. Widely used to evaluate urban canopy schemes such as TEB.
Long-running tall-tower eddy-covariance records of momentum, sensible and latent heat and CO2 over downtown and suburban Indianapolis, with raw 10 Hz data for turbulence statistics.
Quality-controlled half-hourly fluxes of momentum, sensible and latent heat and CO2 from city towers in Zurich and Paris, plus Doppler wind-lidar profiles, released by the EU ICOS Cities (PAUL) project.
Urban atmospheric observations in London, including meteorological measurements on the BT Tower and Doppler lidar boundary-layer wind profiles. Useful for urban wind profiles, roughness and boundary-layer studies.
