Lidar observations by circling the London orbital motorway

Abstract : A field campaign was conducted in London between 15 and 23 June 2009 in order to study the influence of emissions from within the London orbital motorway (M25) in terms of aerosol concentrations within the planetary boundary layer (PBL). The instrumental set-up involves a compact aerosol backscatter lidar, onboard a mobile van, developed by the CEA/LSCE and commercialized by LEOSPHERE Company and in situ instrumentation onboard the British Facility for Airborne Atmospheric Measurements (FAAM) BAe 146 research aircraft devoted to aerosol and gas measurements. For this experiment, the eye-safe lidar has been working at the wavelength of 355 nm. These observations represent the first application of this lidar around the London area. Thanks to the excellent manoeuvrability of the van, we monitored the particulate emissions from vehicles on the M25 by circling the M25.
