Equatorial Waves and Superrotation in the Stratosphere of a Titan General Circulation Model

The Planetary Science Journal, 2023
We investigate the characteristics of equatorial waves associated with the maintenance of superrotation in the stratosphere of a Titan general circulation model.

Atmospheric Escape Processes and Planetary Atmospheric Evolution [PDF]

Journal of Geophysical Research: Space Physics, 2020
AbstractThe habitability of the surface of any planet is determined by a complex evolution of its interior, surface, and atmosphere. The electromagnetic and particle radiation of stars drive thermal, chemical, and physical alteration of planetary atmospheres, including escape.

Joint Application of Concentration and δ18O to Investigate the Global Atmospheric CO Budget

Atmosphere, 2015
Most previous top-down global carbon monoxide (CO) budget estimates have used only concentration information and shown large differences in individual source estimates.

The Hidden Depths of Planetary Atmospheres [PDF]

The Astrophysical Journal, 2018
Abstract Atmospheric regions below a refractive boundary are hidden in limb observations. Refraction thus creates a gray continuum in the planet’s transmission spectrum, which can hide spectral features associated with sources of atmospheric opacity.

Spectroscopic detection and characterisation of planetary atmospheres

EPJ Web of Conferences, 2011
Space based broadband infrared observations of close orbiting extrasolar giant planets at transit and secondary eclipse have proved a successful means of determining atmospheric spectral energy distributions and molecular composition.

Nightside Ionospheric Structure and Composition on Mars Driven by Energetic Electron Precipitation

The Astrophysical Journal, 2023
Ionospheric chemistry plays an unexpectedly important role in the evolution of planetary habitability. This study is dedicated to a detailed modeling of the nightside Martian ionospheric structure and composition, a topic that has been poorly explored ...

Lightning detection in planetary atmospheres [PDF]

Weather, 2017
Lightning in planetary atmospheres is now a well‐established concept. Here we discuss the available detection techniques for, and observations of, planetary lightning by spacecraft, planetary landers and, increasingly, sophisticated terrestrial radio telescopes.

PlanetCARMA: A New Framework for Studying the Microphysics of Planetary Atmospheres

Atmosphere, 2020
The Community Aerosol and Radiation Model for Atmospheres (CARMA) has been updated to apply to atmospheres of the Solar System outside of Earth. CARMA, as its name suggests, is a coupled aerosol microphysics and radiative transfer model and includes the ...
