Volcanic Ash – T+0 annotated satellite image Issued 0315 UTC on Fri 29 Aug 2014 HIGH CONFIDENCE- -Red colour at tip of arrow is meteorological cloud and not VA. -No ash detected by Radar. -No ash detected on geostationary or polar orbiting satellite images. -No lightning detected by Met Office ATDNet, implying no eruptive plume. © Crown copyright Met Office

Volcanic Ash – T+0 annotated satellite image Issued 1230 UTC on Tue 09 Jan 2018 EXERCISE VOLCICE LOW CONFIDENCE- VA suggested by model winds and plume forecast. Radar indicates plume at 24km. However currently not visible due to frontal cloud, and ice on webcams, hence low confidence EXERCISE VOLCICE © Crown copyright Met Office

Volcanic Ash – T+0 annotated satellite image Issued 1345 UTC on Fri 18 May 2018 LOW CONFIDENCE- PIREP reports sighting of VA here, further north than expectations, and none visible in satellite imagery HIGH CONFIDENCE- Large gaps in cloud means VA is clearly visible in satellite imagery © Crown copyright Met Office
