Want to take a moment to compare last 2 eruptions of Tonga #Volcano. Can infer ash plume hgt comparing Bt of IR/WV to near radiosonde profile.

1/13 eruption got to ~15-20 km aloft.
1/15 eruption (today) possibly >30 km! Deep Stratospheric injection likely given sat signature. pic.twitter.com/Q1JSI1IHIr
