From: Using Himawari-8, estimation of SO2 cloud altitude at Aso volcano eruption, on October 8, 2016
The two left figures are the time series (FT = 1(02:46JST)-FT13(14:46JST)) of the JMA-GATM simulations and pilots’ reports. (The upper figure is the result from an initial altitude of SO2 at 5–14 km. The bottom figure is the result from an initial altitude of SO2 at 7–14 km.) The lettered points are pilots’ reports including “VA SMELL” or “SULFUR” as follows: a;06:00JST(FL270–320), b;09:16JST(FL210), c;09:34JST(FL210–240), d;09:50JST(FL180), e;10:20JST(FL190), ff’;10:28JST(FL090), g;10:39JST(FL290), h;13:32JST(FL090–100), xx’;06:08JST(FL370–390), y;08:31JST(FL170), zz’;10:40JST(FL360). FL is flight level (FL100 = 10,000 feet). The right upper figure is SO2 observation from Aura/OMI, 00:35–02:17JST (NASA-GFSC et al. 2016). The right bottom figure is the Ash RGB at 12:46JST
