According to the Ozone Mapping and Profiler Suite (OMPS) lidar-based satellite, measuring the global distribution of ozone as a remote sensing method, it seems the eruption column height has been measured up to 30 km meaning that reached the stratosphere level.
The TROPOMI satellite-based measurements of SO2 concentrations in the atmosphere detected the total mass of about 400000 tonnes – not enough for climate impacts – in the impressive SO2 plume ejected by the volcano on 15 January. Aerosol plumes (mostly tiny droplets of sulphuric acid in the stratosphere, as well as some very fine ash particles) have been traveling along vast stretches in the southern hemisphere.
