This paper presents a review on the PECASUS service, which provides advisories enhanced space weather activity for civil aviation. The are tailored according to Standards and Recommended Practices of International Civil Aviation Organization (ICAO). Advisories disseminated in three impact areas: radiation levels at flight altitudes, GNSS-based navigation positioning, HF communication. review, is based experiences authors from two years running pilot ICAO services, describes empirical models...
Explosive volcanic eruptions can leave behind widespread ash deposits that subsequently be remobilised during strong winds. The London Volcanic Ash Advisory Centre (VAAC), based at the Met Office UK, provides forecasts for resuspended clouds in southern Iceland. In this article we consider a significant event on 24 April 2017, which was captured by VAAC forecast. We examine meteorological observations and NWP data from identify specific synoptic conditions conducive to remobilisation of...
