Since Mauna Loa is, itself, to one side of the equator (I'd need a map - order of a couple of days sailing ; around a thousand km?), it's not purely going to estimate the interhemispheric mixing. Find an equally high volcano similarly placed south of the equator ... oh. How about funding for a labelled release experiment ? Funding !? | |

To get into the stratosphere might take a couple of years, but the stratosphere (and above) is 90%+ of the volume of the atmosphere and a couple of percent by mass. Whichever you think is more important. | |

GHGs from industrial activity does not get injected above the surface mixing layer in the troposphere, let alone the tropopause. Thus, anything released at the surface takes a lot longer than 2 years to get globally mixed. | |
