It has been 10 years since the ash cloud from the eruption of Eyjafjallajökull caused
unprecedented disruption to air traffic across Europe. During this event, the London Volcanic …

This paper discusses how epistemic uncertainties are currently considered in the most
widely occurring natural hazard areas, including floods, landslides and debris flows, dam …

Volcanic eruptions can cause significant disruption to society, and numerical models are
crucial for forecasting the dispersion of erupted material. Here we assess the skill and …

Uncertainty-bounded satellite retrievals of volcanic ash cloud properties such as ash cloud-
top height, effective radius, optical depth and mass loading are needed for the robust …

Developing a comprehensive understanding of the interactions between the atmosphere
and the geosphere is an ever-more pertinent issue as global average temperatures continue …

This paper presents model validation results for the latest version release of the FALL3D
atmospheric transport model. The code has been redesigned from scratch to incorporate …

Modelling atmospheric dispersal of volcanic ash and aerosols is becoming increasingly
valuable for assessing the potential impacts of explosive volcanic eruptions on buildings, air …

Abstract The London Volcanic Ash Advisory Centre (VAAC) provides forecasts on the
expected presence of volcanic ash in the atmosphere to mitigate the risk to aviation. It is …

Currently, the National Oceanic and Atmospheric Administration (NOAA) National Weather
Service (NWS) runs the HYSPLIT dispersion model with a unit mass release rate to predict …

Accurate tracking and forecasting of ash dispersal in the atmosphere and quantification of its
uncertainty are of fundamental importance for volcanic risk mitigation. Numerical models …
