Release Units
Specifies the concentration units of the mass of the released species. The possible options are mass (mass concentration) and mixr (mass mixing ratio). The default value is mass. See the table below to figure out what the actual units mean.
| Simulation Direction | Release Units | Receptor Units | ||
|---|---|---|---|---|
| keyword | units | keyword | units in output concentration grib fields (generated when Output Field Type = conc or both) | |
| Forward | mass | kg | mass | kg m**-3 |
| Forward | mass | kg | mixr | kg kg**-1 |
| Forward | mixr | 1 | mass | kg m**-3 |
| Forward | mixr | 1 | mixr | kg kg**-1 |
| Backward | mass | 1 | mass | s |
| Backward | mass | 1 | mixr | s m**3 kg**-1 |
| Backward | mixr | 1 | mass | s kg m**-3 |
| backward | mixr | 1 | mixr | s |
Releases
Specifies the releases as a group of FLEXPART Release icons.

Enables computing sensitivity to initial conditions in backward simulations. The possible values are none, mass (mass concentration units) or mixr (mass mixing ratio units). The default value is none.
