ALMA2040: Submillimeter-wave Limb Sounding of Venus and Mars
ALMA2040 proposes using high-resolution submillimeter spectroscopy to perform long-term, vertically resolved limb sounding of Venus and Mars atmospheres from the ground. This bridges spacecraft snapshots with temporal evolution by combining high angular resolution with repeated observations across different times and seasons. The goal is to study atmospheric circulation, trace species chemistry, and water loss processes in detail.
