    Very short-lived substances (VSLS) of marine origin, such as bromoform (CHBr3), contribute to stratospheric bromine loading and, thus, to ozone depletion. However, amount, timing, and region of bromine delivery to the stratosphere through one of the main entrance gates, the Asian monsoon circulation, are still uncertain.
