The data were recorded using a proton transfer reaction-time of flight-mass spectrometer (PTR-ToF-MS) from a sampling height of 100m.","keywords":"Volatile Organic Compounds, VOCs, APHH, Beijing","publicationState":"published","dataPublishedTime":"2018-01-11T14:05:37","doiPublishedTime":null,"updateFrequency":"","status":"completed","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/25424/?format=json","dataPath":"/badc/aphh/data/beijing/lanc-gas","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":298161,"numberOfFiles":4,"fileFormat":"Data are NASA Ames formatted"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/6881/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/1856/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/66080/?format=json"],"dataLineage":"Data produced by APHH project participants at University of Lancaster and uploaded to CEDA archive","removedDataTime":null,"removedDataReason":"","language":"English","identifier_set":[],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/24808/?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/105659/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105657/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105658/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105660/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105661/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105662/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105663/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105655/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105656/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105664/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105665/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105666/?format=json"],"procedureAcquisition":"https://catalogue.ceda.ac.uk/api/v2/acquisitions/25427/?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":[{"ob_id":1138,"name":"NDGO0003"}]}
