HYSPLIT Simulations for Eyjafjallajokull (Varying Eruption Date)
The simulations will be computed using HYSPLIT, a model developed by the National Oceanic and Atmospheric Administration (NOAA)'s Air Resources Laboratory. The model is used for trance transport and computes air parcel trajectories; it is similar to ESGlobe, which we used in Project II.
Although the eruptions contributing to the majority of ash fall lasted for 6 days, the simulations will cover the first three days of eruptions.
