Field measurements were carried out at the British Antarctic Survey station, Halley, at the Clean Air Sector Laboratory (CASLab). Year-round measurements began in February 2004, and a summer campaign focussing on oxidants ran during January/February 2005, after which CHABLIS fieldwork ended. The dataset includes URG annular denuder with sodium carbonate coating, nitric acid analysed by IC data.\r\nAccess to this dataset is now public.","keywords":"CHABLIS, NERC, Antarctic, boundary layer","publicationState":"published","dataPublishedTime":"2007-02-23T00:55:35","doiPublishedTime":null,"updateFrequency":"notPlanned","status":"completed","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/740/?format=json","dataPath":"/badc/chablis/data/bas-denuder-hno3","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":5476,"numberOfFiles":2,"fileFormat":"File format is NasaAmes.\r\n"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/208/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/9/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/24537/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/52353/?format=json"],"dataLineage":"Data files submitted as is by the CHABLIS campaign participants in 2005/2006 and archived at the BADC.","removedDataTime":null,"removedDataReason":"","language":"English","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/489/?format=json","https://catalogue.ceda.ac.uk/api/v2/identifiers/8657/?format=json"],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/718/?format=json"],"observationcollection_set":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/715/?format=json"],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/2195/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2194/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2193/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2196/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2197/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2198/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2200/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2216/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/54626/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2202/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2213/?format=json"],"procedureAcquisition":"https://catalogue.ceda.ac.uk/api/v2/acquisitions/742/?format=json","procedureCompositeProcess":null,"procedureComputation":null,"permissions":[{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/2526/?format=json","useLimitation":null,"accessConstraints":null,"accessCategory":"public","accessRoles":null,"label":"public: None group","licenceURL":"http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/","licenceClassifications":"any"}],"discoveryKeywords":[{"ob_id":1138,"name":"NDGO0003"}]}
