Short summary
Halogenated very short-lived substances (VSLSs) are naturally produced in the ocean and emitted to the atmosphere. In the stratosphere, these compounds can have a significant influence on the ozone layer and climate. During a research cruise in the west Indian Ocean, we found an important source region of halogenated VSLSs during the Asian summer monsoon. Modeling the transport from the ocean to the stratosphere we found two main pathways, one over the Indian Ocean and one over northern India.
