The volcanic ash cloud produced covered much of Northern Europe for several weeks causing extensive disruption to air travel. The UK and European atmospheric communities had many instruments - both airborne and ground-based, remote sensing and in-situ - taking measurements of the ash cloud throughout this period. This dataset contains Leosphere and Halo Doppler Lidar images from the Chilbolton Observatory, Hampshire.\r\n","keywords":"Eyjafjallajokull, Lidar, Chilbolton","publicationState":"published","dataPublishedTime":"2014-09-19T13:24:43","doiPublishedTime":null,"updateFrequency":"notPlanned","status":"completed","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/13734/?format=json","dataPath":"/badc/eyjafjallajokull/data/chilbolton","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":14184866,"numberOfFiles":55,"fileFormat":"Images are PNG formatted"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/513/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/92/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/25404/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/54654/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/54655/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/54656/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/54657/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/54658/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/54659/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/54660/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/54661/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/54662/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/54664/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/54665/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/54666/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/54667/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/55839/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/55840/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/55841/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/55842/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/55843/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/55844/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/89372/?format=json"],"dataLineage":"Data collected from the Chilbolton Facility for Atmospheric and Radio Research (CFARR).
