Mixing of air between compartments of the atmosphere is fundamental to atmospheric composition. Such mixing is commonly studied using tracer-tracer correlations. [...]

The Hunga eruption (20° S) in January 2022 injected a substantial amount of water vapor and aerosols into the stratosphere, primarily impacting the Southern Hemisphere and tropics. Using a combination of satellite observations and in situ measurements with optical particle counters, we show that a significant portion of the aerosol plume was transported into the Northern Hemisphere (NH) mid-latitudes.
