Title: Hemispherical Constraint of Titan's Methane Cycle
Abstract: We propose to use Gemini with NIFS/Altair to map weak lines of methane and methal deuteride in Titan's 2-2.11 micron window in the Earth's K band window in order to probe the hemispherical (seasonal) variation of the methane column abundance in Titan's atmosphere and thereby constrain its seasonal transport. The results will help to clarify whether volatile, high-latitude lakes drive a global-scale methane cycle in Titan's atmosphere and to constrain GCM models of Titan.
