A case study
In this case study will run FLEXPART to simulate the imaginary eruption of the Icelandic volcano Eyjafjallajökull.
...
We will run FLEXPART to simulate the release of a volcano eruption by releasing of some SO2 from the Icelandic volcano Eyjafjallajökull.
The simulation is defined via by the 'fwd_conc' FLEXPART Run icon and the 'rel_volcano' FLEXPART Release icons icon, respectively. Both these are encompassed in the a single Macro called 'fw_cond.mv' Macro. For simplicity will use this macro to show examine the simulation settings in detail.
First we define the release like this:
Code Block | ||
---|---|---|
| ||
rel_volcano = flexpart_release( name : "REL 1VOLCANO", starting_date : 0, starting_time : 15, ending_date : 2, ending_time : 12, area : [63.63,-19.6,63.63,-19.6], top_level : 9000, bottom_level : 1651, particle_count : 10000, masses : 1001000000 ) |
This says that the release will happen over a 45 h period between heights 1651 and 10000 m at the location of the volcano and we will release 100 kg worth of particles1000 tons of material.
