On Table 1 of your study, it’s measuring residence time of stratospheric water vapor in days. How are you getting years from that?
- JAlexoid 6y agoThe article doesn't mention the water vapor lifetime in stratosphere... But they do mention that cryoplanes should not fly close to tropopause, for the fear of water vapor escaping to stratosphere.
- Hypx 6y agoIt states: > f Residence time = accumulated H2O divided by emitted H2O (days). Corresponding values for the stratosphere only are given in parenthesis. That seems like it is in days. Unless there's something that I missed, I'm not seeing the part that claims water vapor lasts for years in the stratosphere.
