Two Kipp and Zonen (UK) PREDE POM01-L sunphotometers were used: June 2001 - March 2008 (Unknown serial number) and August 2009 - December 2023 (Serial  Number PS08015). \r\n\r\nThe instruments operated at 7 wavelengths (315, 400, 500, 670, 870, 940 and 1020nm) and scanned at pre-set angles away from the solar disk to determine, using the inversion code of Nakajima et al. (1996), various optical properties of tiny particles called aerosols within the atmospheric column.","keywords":"ACSIS, aerosol, PML, photometer","publicationState":"citable","dataPublishedTime":"2024-01-30T08:03:21","doiPublishedTime":"2024-01-31T14:19:35.067207","updateFrequency":"","status":"ongoing","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/41411/?format=json","dataPath":"/badc/acsis/pml-sunphotometer/data/v1","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":63129401,"numberOfFiles":4,"fileFormat":"BADC-CSV, txt"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/11526/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/4126/?format=json","nonGeographicFlag":false,"phenomena":[],"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":["https://catalogue.ceda.ac.uk/api/v2/identifiers/12807/?format=json"],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/24717/?format=json"],"observationcollection_set":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/24737/?format=json"],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/201710/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/201711/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/201712/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/201713/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/201714/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/201715/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/201716/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/201726/?format=json"],"procedureAcquisition":"https://catalogue.ceda.ac.uk/api/v2/acquisitions/41412/?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, attribution required"}],"discoveryKeywords":[]}
