From: Using Himawari-8, estimation of SO2 cloud altitude at Aso volcano eruption, on October 8, 2016
Results of the SO2 simulations by JMA-GATM. Upper row: simulation from initial altitude of SO2 at 2–7 km. Middle row: simulation from initial altitude of SO2 at 7–14 km. Bottom row: simulation from initial altitude of SO2 at 14–17 km. The left column is approximately 1 h after eruption (02:46JST). The center column is approximately 3 h after eruption (04:46JST). The right column is approximately 5 h after eruption (06:46JST). The color bar indicates the height [m] of SO2 tracers
