U34A:
Are We Ready to Observe the Next Large Volcanic Eruption?

Note: Abstract submissions to Union sessions are by invitation only.


Session ID#: 7470

Session Description:
The next large-magnitude volcanic eruption offers the opportunity to observe the injection of particles and gases into the stratosphere, the formation of sulfate aerosol particles, the evolution of their size distribution, their transport, their lifetime, their impact on ozone chemistry and stratospheric dynamics, and their modification of Earth’s radiative budget.  What needs to be observed, how promptly and at what time and space resolution, to initialize forecasting systems to predict the next season’s climate and to learn about proposed stratospheric geoengineering schemes?  Are our current observing systems capable of making all relevant measurements?  If not, what could be designed to be ready for the eruption and take useful observations in the meantime?  What background state observations do we need in advance of a major eruption?  What are the probabilities and current candidates for major eruptions and do we understand the mix of emitted species for various eruption types?
