Abstract
⺠We have fitted 7 years of Io 19 μm spectra from 2001 to 2010. ⺠Data shows SO2 atmospheric temperatures are below 150 K, with a mean of 110 ± 18 K. ⺠Sub-solar SO2 grew from 0.61 ± 0.15 (2004) to 1.51 ± 0.22 (Ã10â17 cmâ2) (2010). ⺠Good correlation of increasing atm. density with decreasing heliocentric distance. ⺠Constraints on thermal inertia and albedos of SO2 frost were retrieved.
