Volcanic ash

European domain 0-24 hour ash concentration graphics

Modelled volcanic ash concentration forecasts are available below. Volcanic Ash Forecasts are only available from London VAAC for volcanoes erupting within the London VAAC area.

These charts supplement the London Volcanic Ash Advisory graphics (VAG) and advisories (VAA). They are to be used with caution. The outer edge of the low concentration zones (indicated as cyan) on these charts represent the standard threshold (200 micrograms of ash per cubic meter) as used

Dr Michael Cooke

. Mike's work aims at developing the use of these sensors to improve the information available to the London Volcanic Ash Advisory Centre (VAAC). Career Background Mike has been working in the Satellite Applications group since autumn 2010. Before joining the Met Office, he studied at the University of Bristol and gained a PhD in Chemistry. His research focused on the global simulation of tropospheric ozone using detailed chemical mechanisms.
