Abstract
AbstractJupiter's oxygen content is inextricably tied to its formation history and the evolution of the early solar system. Recent one-dimensional thermochemical modeling of CO showed that the planet's bulk water content could be subsolar, in stark contrast to the water enrichment determined near the equator using theJunospacecraft. Here, we use a hydrodynamic model to study Jupiter's atmospheric dynamics at and below the water cloud level with simplified CO thermochemistry to show the effect of hydrodynamics on the abundance of CO in the troposphere. Our dynamical modeling results are inconsistent with the 0.3 times solar water enrichment levels. Furthermore, we reveal a correlation between moist convection and the CO abundance at the water cloud level. If such a correlation is found observationally, subsolar water abundance can be ruled out.
