Radiative transfer and inversion codes for characterizing planetary atmospheres: an overview

Frontiers in Astronomy and Space Sciences, 2023
The study of planetary atmospheres is crucial for understanding the origin, evolution, and processes that shape celestial bodies like planets, moons and comets.

Strong Depletion of 13C in CO Induced by Photolysis of CO2 in the Martian Atmosphere, Calculated by a Photochemical Model

The Planetary Science Journal, 2023
The isotopic signature of atmospheric carbon offers a unique tracer for the history of the Martian atmosphere and the origin of organic matter on Mars. The photolysis of CO _2 is known to induce strong isotopic fractionation of the carbon between CO _2 ...

Study of atmospheres in the solar system, from stellar occultation or planetary transit

Comptes Rendus. Physique, 2022
Stellar occultations and transits occur when a planetary body passes in front of a star (including our Sun). For objects with an atmosphere, refraction plays an essential role to explain the drops of flux and the aureoles observed during these events ...

Depletion of 13C in CO in the Atmosphere of Mars Suggested by ExoMars-TGO/NOMAD Observations

The Planetary Science Journal, 2023
The atmosphere of Mars is mainly composed by carbon dioxide (CO _2 ). It has been predicted that photodissociation of CO _2 depletes ^13 C in carbon monoxide (CO).

Soft X-Ray-induced Dimerization of Methane

The Astrophysical Journal, 2023
Carbon 1s excitation of methane, CH _4 , has been studied in the gas phase using the ion trap integrated with the photon–ion instrument at PETRA III/DESY and soft X-rays from the beamline P04.

Planetary atmospheres [PDF]

Astronomical School’s Report, 2009
The theoretical and observational aspects of research ofplanetary atmospheres and their main satellites are presented. Physics of atmosphere, its structure, making climatefactors, stability of atmospheres to dissipation of basic gases, applicability of theory of similarity to the study ofatmosphere and its general circulation are considered.

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.
