Question:
I am doing a project on air pollution due to Volcanic activity. I am missing one major part of the project: a model for the plume so that I can calculate the contaminant dispersion. I was wondering if one of you were familiar with such models and if I could get any information about them.
Answer:
Here are several sources of information for you:
https://www.ready.noaa.gov/HYSPLIT.php – This is a more general application of the HYSPLIT transport and dispersion model. You can run the model on the web, but it has a pre-set source of 1.0 micron dia. particles. The model may be downloaded so you can run it yourself; you then can set the source, the particle size, density, etc. Model documentation is also on the web.
http://www.ssd.noaa.gov/VAAC/washington.html – Washington Volcanic Ash Advisory Center – Has much information on volcanoes – focusing on aviation hazards. Also included are links to the other Volcanic Ash Advisory Centers. I hope this will help you with your project.

Post questions, comments and links to research (research papers, web sites, etc) involving HYSPLIT and volcanic ash. This section is also to facilitate collaborations between researchers involved in volcanic ash transport and dispersion.
