| Zusammenfassung |
| Sander et al. (2006) proposed that CaCO3 precipitation can be an
important factor in triggering tropospheric ozone depletion events.
Recently, Morin et al. (2008b) presented calculations with the FREZCHEM model
and concluded that their results and interpretation cast doubt on the
validity of this hypothesis. In this joint publication, we have
re-analyzed the implications of the FREZCHEM results and show how they
can be reconciled with the proposal of Sander et al. (2006). The chemical
predictions of both approaches are consistent. Although an
interpretation solely based on the alkalinity change in the brine does
not support the conclusion of Sander
et al. (2006), we show that the
bromide/alkalinity ratio (which increases during the cooling of the
brine) can be used as an indicator of the potential for triggering
bromine explosions. |
