South Asian Monsoon: whole air sample halocarbon measurements onboard FAAM aircraft flights
This dataset contains halocarbon measurements made from whole air samples collected on board the FAAM (Facility for Airborne Atmospheric Measurements) aircraft during the NERC (National Environmental Research Council) South West Asian Aerosol Monsoon Interactions (SWAAMI) project and the Interaction of Convective Organization and Monsoon Precipitation, Atmosphere, Surface and Sea (INCOMPASS) project - both of which were funded under the 'Drivers of Variability in the South Asian Monsoon' programme.
Whole air samples were collected in 3 L stainless steel cylinders (WAS flasks) aboard the FAAM aircraft during 11 flights (b957, b959, b963, b966, b968, b969, b971, b972, b974, b975, b976). In total, 176 samples were collected above India and the Indian Ocean, from the 12th June - 10th July 2016. Samples were returned to the University of Bristol for analysis by Medusa Gas Chromatography Mass Spectrometry, resulting in concentration (mole fraction) data for chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and chlorocarbons (e.g. dichloromethane). Each sample was analysed three times in total, with the reported mole fraction taken to be the average of these three analyses. Samples were collected by Daniel Say, with significant input from Anita Ganesan (flight planning) and Simon O'Doherty (interpretation of measurements).
