Temperatures and CH₄ mixing ratios near the homopause of the 8 µm north polar hot spot of Jupiter

Orton, G. S.; Kim, Sang Joon; Yung, Yuk L. +4 more

We have derived homopause temperatures of 180-250 K for the 8-µm north-polar hot spot (8NPHS) of Jupiter by fitting CH₄ emission models to 3 and 8 µm spectra of the 8NPHS obtained 24 days apart in 2013. From the fits, we find that CH₄ mixing ratios at the 8NPHS are consistent with those reported by Kim et al. (201…
