The Deuterium Isotopic Ratio of Water Released From the Martian Caps as Measured With TGO/NOMAD
Geophysical Research Letters, 2022 We report vertical profiles of water and D/H for one Martian year as measured with the TGO/NOMAD instrument. The observations were performed via solar occultation, providing water profiles up to ∼100 km and D/H up to ∼60 km, with a vertical resolution of
