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 contains Formaldehyde concentration measured by Aerolaser HCHO Monitor Model AL4021. Access to this dataset is now public.","keywords":"CHABLIS, NERC, Antarctic, boundary layer, hcho","publicationState":"published","dataPublishedTime":"2007-02-23T00:45:11","doiPublishedTime":null,"updateFrequency":"notPlanned","status":"completed","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/727/?format=json","dataPath":"/badc/chablis/data/bas-aerolaser-hcho","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":2761868,"numberOfFiles":20,"fileFormat":"NASA-Ames"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/205/?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/25849/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/83612/?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/479/?format=json","https://catalogue.ceda.ac.uk/api/v2/identifiers/8660/?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/2115/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2114/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2113/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2116/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2117/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2118/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2124/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2136/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/54623/?format=json"],"procedureAcquisition":"https://catalogue.ceda.ac.uk/api/v2/acquisitions/729/?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"}]}
