Blue shaded area shows parameter space where model predicts SO2
mixing ratios between 0.01 and 1 ppm at 100 km
Golden line = max values of SO2 (67 ppb) from microwave measurements of Sandor et al (2010)
No change in SO2 above 80 km due to pulse in lower atmosphere
ÔÉ®Vulcanism not the source of SO2 above this point
