In this tutorial we will simulate a volcano eruption by releasing some SO2 from the Icelandic volcano Eyjafjallajökull and visualise the results in various ways. |
The simulation itself is defined by the 'fwd_conc' FLEXPART Run icon and the 'rel_volcano' FLEXPART Release icon, respectively. Both these are encompassed in a single macro called 'fwd_conc.mv'. For simplicity will use this macro to examine the settings in detail.

Here we defined both the input and output path and specified the simulation period, the output grid and levels as well. We also told FLEXPART to generate gridded mass concentration and flux fields and plume trajectories on output..
