On the Effect of Magnetospheric Shielding on the Lunar Hydrogen Cycle

Farrell, W. M.; Tucker, O. J.; Poppe, A. R.

The global distribution of surficial hydroxyl on the Moon is hypothesized to be derived from the implantation of solar wind protons. As the Moon traverses the geomagnetic tail, it is generally shielded from the solar wind; therefore, the concentration of hydrogen is expected to decrease during full Moon. A Monte Carlo approach is used to model the…
