Flexpart Volcanic Tracer Forecast 

Turrialba (10.03 N, 83.77 W) emission tracer forecasts are calculated with the particle dispersion model FLEXPART based on Global Forecast System (GFS) data of the National Centre for Environmental Prediction (NCEP). Tracer (SO2) masses distributed within 5, 10 and 15 km column a.g.l are carried by particles following trajectories calculated using the GFS winds and stochastic components for turbulence and convection.
