Saturn's Temperature Field from High-Resolution Middle-Infrared Imaging

摘要

Saturn was imaged between 8 and 24.5 micrometers at ～3000-kilometer resolution with the Keck I Telescope. Saturn's atmosphere has zonal temperature bands, which are mostly uncorrelated with visible cloud reflectivity, strong 100-miltibar zonal temperature oscillations near 32°S, a warm south polar cap, and a compact hot point within 3° of the south pole.
