Surface pressure cycle on Triton as simulated with the VTM assuming a different fixed N₂ ice distribution in both hemispheres. A thermal inertia of 1000 J s^−1/2 m⁻² K⁻¹ (SI) was assumed. Bertrand et al. (2022) include more simulations in their paper, and their Fig. 9 shows cases with different thermal inertias. It is of note that their simulations show that a lower thermal inertia would delay the peak of the surface pressure, in opposition with the occultation data points. The blue lines refer to a southern cap extending to the equator, while the pink lines are for a southern cap extending to 30° S. Each line, marked with its corresponding value, refers to a different extension of the northern cap: 45° N, 60° N, 75° N, and no cap.
