In collaboration with Leeds, participation in the TORCH 2004 field campaign.\r\n-Obtain parallel measurements for as many NMHCs as can be resolved and deconvoluted by GC-MS techniques. Key species included isoprene, 1,3-butadiene, benzene and toluene together with the n- and iso- C2 to C6 alkanes.\r\n-From the resolved OVOCs and NMHC measurements investigation was made into hydrocarbon degradation products in air of different photochemical age and origin.","keywords":"Polluted Troposphere, OVOCs, NMHCS, Chemistry","status":"","publicationState":"published","identifier_set":[],"observationCollection":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/14346/?format=json"],"parentProject":"https://catalogue.ceda.ac.uk/api/v2/projects/1345/?format=json","subProject":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/45988/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/55780/?format=json"]}
