Developmental SEVIRI-based
Volcanic Ash Trajectory Predictions

July 30, 2010 - As part of activities under the NOAA Volcanic Ash Working Group (VAWG) Science Team, Advanced Satellite Products Branch (ASPB) scientists Brad Pierce and Mike Pavolonis used aerosol trajectory forecast capabilities from the International version of Infusing Satellite data into Environmental Applications (IDEA-I) to demonstrate how Spinning Enhanced Visible and Infrared Imager (SEVIRI) volcanic ash visible optical depth and ash top pressure retrievals could be used to initialize volcanic ash trajectory predictions associated with the April 2010 Eyjafjoll eruption in southern Iceland. IDEA-I trajectory initialization software was adapted for SEVIRI ash retrievals and delivered to scientists at the NOAA Air Resources Laboratory (ARL) for use in Operational HYbrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) volcanic ash predictions.

The IDEA-I trajectories are colored by their pressure (mb) and were initialized using SEVIRI ash visible optical depth (colored circles) and ash top pressure retrievals provided by Mike Pavolonis (NESDIS/STAR). 500mb wind predictions from the NWS Global Forecasting System (GFS) are shown in white.
