Attend webinars on new volcanic ash forecast services
The London Volcanic Ash Advisory Centre (VAAC) operated by the Met Office is an International Civil Aviation Organization (ICAO) designated centre, responsible for issuing advisories for volcanic eruptions originating in Iceland and the north-eastern corner of the North Atlantic.
The Met Office is pleased to announce that, in accordance with Amendment 82 to ICAO Annex 3 Meteorological Service for International Air Navigation and the first edition of Doc 10157 (PANS-MET) a new Quantitative Volcanic Ash (QVA) forecast service will become available for the first time on 27 November 2025. The new QVA service will provide higher resolution ash location information compared to traditional Volcanic Ash Advisory (VAA) products. Further details are available in an AIC issued on 21 August 2025.
The Met Office is running two webinars where you can learn more about QVA forecasts and how to obtain these through a new QVA API.
