Ionosphere Influenced From Lower-Lying Atmospheric Regions

Frontiers in Astronomy and Space Sciences, 2021
The ionosphere represents part of the upper atmosphere. Its variability is observed on a wide-scale temporal range from minutes, or even shorter, up to scales of the solar cycle and secular variations of solar energy input.

A revised lower estimate of ozone columns during Earth’s oxygenated history [PDF]

Royal Society Open Science, 2021
The history of molecular oxygen (O2) in Earth’s atmosphere is still debated; however, geological evidence supports at least two major episodes where O2 increased by an order of magnitude or more: the Great Oxidation Event (GOE) and the Neoproterozoic ...

Exoplanet secondary atmosphere loss and revival [PDF]

Proceedings of the National Academy of Sciences, 117, 18264-18271 (2020), 2020
The next step on the path toward another Earth is to find atmospheres similar to those of Earth and Venus - high-molecular-weight (secondary) atmospheres - on rocky exoplanets. Many rocky exoplanets are born with thick (> 10 kbar) H$_2$-dominated atmospheres but subsequently lose their H$_2$; this process has no known Solar System analog.
