2019 Workshop: Light Atoms Across Atmospheric Regions
Light atoms play key roles in determining the dynamics and composition of the middle and upper atmosphere, as well as for the ionosphere and plasmasphere through charge exchange reactions. Neutral hydrogen is a by-product of methane and water vapor below, two principal gases involved in the radiative balance of the Earth’s atmosphere. We invite presentations relating to modeling and observational studies of light atoms (H, O, He) in and/or across any of the atmospheric regions. There will also be time for informal discussion.
