Model-based aviation advice on distal volcanic ash clouds by assimilating aircraft in situ measurements:
The forecast accuracy of distal volcanic ash clouds is important for providing valid aviation advice during volcanic ash eruption. However, because the distal part of volcanic ash plume is far from the volcano, the influence of eruption information on this part becomes rather indirect and uncertain,...
