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.Here are several sources of information for you: http://www.arl.noaa.gov/READYVolcAsh.php - You may run the HYSPLIT model on the web for any volcano. This version of HYSPLIT is configured specifically for volcanic ash. A description of the model and references are given. http://www.arl.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.
