  • This dataset contains volatile organic compound (VOC) fluxes recorded during two intensive field campaigns in Beijing (winter: 12/11/2016 - 10/12/2016; and summer: 15/05/2017 - 24/06/2017) as part of the Atmospheric Pollution & Human Health in a Chinese Megacity (APHH) programme. VOC concentrations were recorded using the GIG: Proton Transfer Reaction-Time of Flight- Mass Spectrometer (PTR-ToF-MS). Measurements were made at 102 m on the Institute of Atmospheric Physics (IAP) meteorological mast. Fluxes were processed by Lancaster University.

  • ClearfLo (Clean Air for London) Project was a collaborative scientific project involving several academic institutions in the UK, which aimed to set up air pollution monitoring sites alongside meteorological measurements to investigate boundary layer pollution across London. This dataset contains NAME airmass footprint images and measurements of ammonia, carbon dioxide, methane, carbon monoxide, nitrogen, nitrogen oxide and ozone at the BT-Tower, London.

  • ClearfLo (Clean Air for London) Project was a collaborative scientific project involving several academic institutions in the UK, which aimed to set up air pollution monitoring sites alongside meteorological measurements to investigate boundary layer pollution across London. This dataset contains NAME airmass footprint images and measurements of ammonia, nitrate, sulphate, chloride and carbon monoxide at North Kensington, London.

  • ClearfLo (Clean Air for London) Project was a collaborative scientific project involving several academic institutions in the UK, which aimed to set up air pollution monitoring sites alongside meteorological measurements to investigate boundary layer pollution across London. This dataset contains and measurements of ozone and carbon monoxide at Chilbolton Observatory.

  • The NERC URGENT thematic programme was set up to integrate urban environmental research across the geological, ecological, freshwater and atmospheric sciences. It worked in partnership with city authorities, industry and regulatory bodies. Airborne Particulate Pollutants: PHYsicochemistry and TOXicity (PHYTOX) is a NERC Urban Regeneration and the Environment (URGENT) Air project (GST/02/2222 - Duration: 1/10/1998 - 30/9/2001) led by Prof Roy Richards, University of Wales, Cardiff. The objectives of this project were: -to collect and provide detailed physiochemical analysis of PM10 (defined as particulate matter which has an aerodynamic diameter of less than 10microns) from four sites (industrial, densely populated urban, open cast mining and rural) in the South Wales conurbation -to examine the ability of the characterised samples of PM10 to produce lung inflammation, increase lung permeability or initiate epithelial damage -to determine if the effects are transient or progressive. This project has a multi-disciplinary approach to collect, quantify, physicochemically characterise and determine the respiratory toxicology of different samples of airborne particles. The research is especially timely because of the increasing concerns by government, medical and environmental professionals about possible adverse health effects of particulate pollution. In addition, there is growing public concern, particularly amongst asthmatics and the healthy population, who live near traffic or other particle-generating sources, that airborne pollutants may be detrimental to health.

  • The Emissions around the M25 motorway (EM25) campaign took place over the megacity of London in the United Kingdom in June 2009 with the aim of characterising trace gas and aerosol composition and properties entering and emitted from the urban region. It featured two mobile platforms, the UK BAe-146 Facility for Airborne Atmospheric Measurements (FAAM) research aircraft and a ground-based mobile lidar van, both travelling in circuits around London, roughly following the path of the M25 motorway circling the city. This dataset collection contains atmospheric airborne and insitu measurements.

  • Airborne Particulate Pollutants: PHYsicochemistry and TOXicity (PHYTOX) was a Natural Environment Research Council (NERC) Urban Regeneration and the Environment (URGENT) Air project (GST/02/2222 - Duration: 1/10/1998 - 30/9/2001) led by Prof Roy Richards, University of Wales, Cardiff. This dataset contains rat atmospheric pollution exposure measurements.

  • The Brazil-UK Network for Investigation of Amazonian Atmospheric Composition and Impacts on Climate (BUNIAACIC) collaboration was a NERC (Natural Environment Research Council) funded project (NE/I030178/1) This project aimed to develop a coherent strategy for UK studies of atmospheric composition and impacts in the Amazon. This dataset contains flags to indicate pollution episodes during the BUNIAACIC deployment.

  • This dataset contains chemical composition measurements of PM2.5 particles made at the Institute of Atmospheric Physics land station (IAP), Beijing site during the winter APHH-Beijing campaign for the Atmospheric Pollution & Human Health in a Chinese Megacity (APHH) programme. Daily fine particles were collected on the PTFE (Polytetrafluoroethylene) filters using the Partisol samplers. The filters were then analysed for metals using X-ray fluorescence (XRF) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and for ion species using Ion Chromatography. Quartz filters were collected by Tisch high vol, samplers and then were analysed for organic and elemental carbons using the DRI Model 2015 Multiwavelength Thermal/Optical Carbon Analyser, and organic tracers using Gas chromatography–mass spectrometry (GC-MS).

  • This dataset contains Laser induced fluorescence (LIF) OH reactivity measurements made at the Institute of Atmospheric Physics land station (IAP), Beijing site during the winter and summer APHH-Beijing campaigns for the Atmospheric Pollution & Human Health in a Chinese Megacity (APHH) programme. The Leeds OH reactivity instrument measures OH reactivity by photolysing ozone at 266 nm to produce OH, decay of OH with ambient air is measured with LIF (laser induced fluorescence) at 308 nm. The results generate a bi-exponential curve and a line of best fit can be used to calculate OH lifetime. The instrument is calibrated by flowing air zero through the instrument. The units for OH reactivity is in s-1. The data has been filtered for instrument instabilities such as pressure, laser power, high background (laser scatter) and laser alignment
