Pluto’s Volatile and Climate Cycles on Short and Long Timescales
The volatiles on Pluto’s surface, N2, CH4, and CO, are present in its atmosphere as well. The movement of volatiles affects Pluto’s surface and atmosphere on multiple timescales. On diurnal
New Constraints on Pluto’s Sputnik Planitia Ice Sheet from a Coupled Reorientation–Climate Model
We present a coupled reorientation and climate model, to understand how true polar wander (TPW) and atmospheric condensation worked together to create the Sputnik Planitia (SP) ice sheet and reorient
A bimodal distribution of haze in Pluto’s atmosphere
Pluto, Titan, and Triton make up a unique class of solar system bodies, with icy surfaces and chemically reducing atmospheres rich in organic photochemistry and haze formation. Hazes play important

Haze in Pluto's atmosphere
Observed glacier and volatile distribution on Pluto from atmosphere–topography processes
The model predicts N2 ice accumulation in the deepest low-latitude basin and the threefold increase in atmospheric pressure that has been observed to occur since 1988, and points to atmospheric–topographic processes as the origin of Sputnik Planitia’s N2 glacier.
The CH4 cycles on Pluto over seasonal and astronomical timescales
Pluto's lower atmosphere and pressure evolution from ground-based stellar occultations, 1988-2016
Context. Pluto's tenuous nitrogen (N2) atmosphere undergoes strong seasonal effects due to high obliquity and orbital eccentricity, and has been recently (July 2015) observed by the New Horizons
On the global distribution of Pluto's atmosphere
Pluto's volatile atmosphere currently extends essentially uniformly around the globe and has nearly uniform thickness, discounting topographic elevation differences and tidal effects. Although in
