Airborne Measurements of Volcanic Ash and Current State of Ash Cloud Prediction
Eyjafjallajökull 2010 and Grímsvötn 2011 eruptions created great problems for commercial aviation in the North Atlantic because of the large extent of the predicted ash clouds from these eruptions. Comparison to satellite pictures showed the predictions very much larger than the ash cloud. Measureme...
