REFIR- A multi-parameter system for near real-time estimates of plume-height and mass eruption rate during explosive eruptions
Publisher's version (útgefin grein) Meaningful forecasting of the atmospheric concentration and ground accumulation of volcanic ash during explo-sive eruptions requires detailed knowledge of the eruption source parameters. However, due to the large uncer-tainties in observations and limitations...
