Aleinov, I., M.J. Way, C. Harman, K. Tsigaridis, E.T. Wolf, and G. Gronoff, 2019: Modeling a transient secondary paleolunar atmosphere: 3-D simulations and analysis. Geophys. Res. Lett., 46, no. 10, 5107-5116, doi:10.1029/2019GL082494.

The lunar history of water deposition, loss, and transport post-accretion has be come an important consideration in relation to the possibility of a human outpost on the Moon. Very recent work has shown that a secondary primordial atmosphere of up to 10 mb could have been emplaced ∼3.5×109 years ago due to volcanic outgassing from the maria. Using a zero dimensional chemistry model we demonstrate the temperature dependence of the resulting major atmospheric components (CO or CO2). We use a three dimensional general circulation model to test the viability of such atmosphere and derive its climatological characteristics. Based on these results we then conjecture on its capability to transport volatiles outgassed from the maria to the permanently shadowed regions at the poles. Our preliminary results demonstrate that atmospheres as low as 1 mb are viable and that permanent cold trapping of volatiles is only possible at the poles.
