Woods, National Physical Laboratory (NPL). \r\n\r\nThis dataset contains atmospheric methane measurements from a balloon-borne near-IR laser spectrometer.\r\n\r\nThe data shows the methane mixing ratio at different atmospheric pressures. The overall scientific objective within this proposal was to contribute to the understanding of middle latitude ozone loss by making measurements of a number of important tracers of atmospheric motion and photochemistry, and by interpreting these measurements with state-of-the-art models of atmospheric chemistry and transport.\r\n","keywords":"UTLS, THESEO, balloon, chemistry","publicationState":"published","dataPublishedTime":"2007-03-13T15:32:42","doiPublishedTime":null,"updateFrequency":"notPlanned","status":"completed","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/4035/?format=json","dataPath":"/badc/utls/data/theseo/npl","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":70637,"numberOfFiles":7,"fileFormat":"Data are NASA Ames formatted"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/1149/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/779/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/25398/?format=json"],"dataLineage":"Data collected by balloon-borne near-infra-red tunable diode laser spectrometer from the National Physical Laboratory (NPL), launched from Kiruna during the 1999/2000 winter, then interpreted using 3D chemical transport models already developed at Cambridge.\r\nData files were provided as is in 2000 to the BADC for archiving.","removedDataTime":null,"removedDataReason":"","language":"English","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/2767/?format=json"],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/14405/?format=json"],"observationcollection_set":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/4033/?format=json"],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/19632/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/19634/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/19635/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/19636/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/19637/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/55933/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/19629/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/19631/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/55934/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/55935/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/55936/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/55937/?format=json"],"procedureAcquisition":"https://catalogue.ceda.ac.uk/api/v2/acquisitions/4037/?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"}]}
