The variable IVULCAN selects one of the predefined stratospheric aerosol model, thus defining the aerosol optical properties (i.e., extinction, absorption and scattering) and vertical profile used for the stratospheric-layer (10-30 km). The available options are shown in the Table below:
Value(s) | Description |
---|---|
1 |
Background stratospheric Default value
|
2 |
Moderate volcanic aerosols
|
3 |
High volcanic aerosols |
4 |
Extreme volcanic aerosols |
This variable, therefore, has an impact on the simulation of the absorption-scattering processes caused by suspended particles in the sun-target-sensor optical path.
The amount/vertical profile of suspended particles is fixed .
