摘要: Explosive volcanic eruptions have the potential to inject gases including sulphur dioxide (SO2) and silicate ash into upper lower stratospheres, which not only has climatic implications but also poses a significant hazard for aircraft flying at these altitudes. The effects of on engines main airframe are well documented although acidic less known, both species result in hazardous extremely costly damage. 2009 eruption Sarychev Peak, Kuril Islands, affected large number flights busy North Pacific (NOPAC) region. Here we observe differential transportation SO2 using satellite-based sensors Atmospheric Infrared Sounders (AIRS) Moderate Resolution Imaging Spectroradiometer (MODIS), highlighting usefulness limitations comparing observed data predicted dispersion from National Oceanic Administratio...
