Allison Ring and Alice Crawford developed a prototype web page which produces HYSPLIT trajectory runs based on alerts produced by the volcanic cloud monitoring system at NESDIS-CIMSS (the National Environmental Satellite, Data, and Information Service – Cooperative Institute for Meteorological Satellite Studies). More information on the alerts can be found at and the prototype web page with HYSPLIT trajectories can be found at The web page is the one of the first steps in developing a system which will incorporate satellite information on volcanic clouds into the HYSPLIT modeling system.

Alice Crawford extended the experimental ensemble fire-smoke HYSPLIT products from the CONUS to Alaska. The products can be found at
