Remote sensing is an important tool to track hazardous volcanic plumes, providing an overview of the ash cloud. Francis et al. describe a method of using infrared data from instruments on board the Meteosat satellite to detect volcanic ash and derive quantitative measurements of its physical properties. They demonstrated their technique using data from the 2010 Eyjafjallajökull eruption and validated their retrieved properties against space-borne and airborne lidar data. They show that their retrieved properties are realistic, and the method should help improve ash cloud analysis and forecasting.
