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.","keywords":"Eyjafjallajokull, MST Radar","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/13762/?format=json","dataPath":"/badc/eyjafjallajokull/data/mstrf","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":499020,"numberOfFiles":11,"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/515/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/25388/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/25393/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/25404/?format=json"],"dataLineage":"Data collected  from the MST Radar Facility's.
