Seasonal evolution of Titan's stratosphere during the Cassini mission

Abstract:

Titan's stratosphere exhibits significant seasonal changes, including breakup and formation of polar vortices. Here we present the first analysis of midinfrared mapping observations from Cassini's Composite InfraRed Spectrometer to cover the entire mission (Lₛ=293–93°, 2004–2017)—midnorthern winter to northern summer solstice. The north polar winter vortex persisted well after equinox, starting breakup around Lₛ∼60° and fully dissipating by Lₛ∼90°. Absence of enriched polar air spreading to l...
