The chamber experiments were carried out with hydroxyl (OH) radical as oxidant in both high- and low-NOx conditions and the resultant aerosol samples were collected using quartz filters and analysed by the two dimensional Gas Chromatography Time-Of-Flight Mass Spectrometry (GC×GC-TOFMS) at the University of Birmingham.","keywords":"APHH, aerosol","publicationState":"published","dataPublishedTime":"2024-02-15T14:26:01","doiPublishedTime":null,"updateFrequency":"","status":"ongoing","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/41477/?format=json","dataPath":"/badc/aphh/data/beijing/bham-gc-pam/","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":10072,"numberOfFiles":3,"fileFormat":"BADC-CSV"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/11561/?format=json","geographicExtent":null,"nonGeographicFlag":true,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/79912/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/79913/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/79914/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/79915/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/79916/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/79917/?format=json"],"dataLineage":"Data were produced by the project team and supplied for archiving at the Centre for Environmental Data Analysis (CEDA).","removedDataTime":null,"removedDataReason":"","language":"English","identifier_set":[],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/24808/?format=json","https://catalogue.ceda.ac.uk/api/v2/projects/41476/?format=json"],"observationcollection_set":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/24817/?format=json"],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/202161/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/202154/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/202155/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/202156/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/202157/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/202158/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/202159/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/202153/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/202160/?format=json"],"procedureAcquisition":"https://catalogue.ceda.ac.uk/api/v2/acquisitions/41479/?format=json","procedureCompositeProcess":null,"procedureComputation":null,"permissions":[{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/2522/?format=json","useLimitation":null,"accessConstraints":null,"accessCategory":"registered","accessRoles":null,"label":"registered: None group","licenceURL":"http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/","licenceClassifications":"any, attribution required"}],"discoveryKeywords":[]}
