Longitudinal variability of thermospheric zonal winds near dawn and dusk

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Understanding the morphology and dynamics of the thermosphere is key to understanding the Earth’s upper atmosphere as a whole. Thermospheric winds play an important role in this process by transporting momentum and energy and affecting the composition ...

Scientific motivations and future directions of whole atmosphere modeling

open access: yesFrontiers in Astronomy and Space Sciences, 2022
The recent development of whole atmosphere models that extend from the surface to the upper thermosphere represents a significant advance in modeling capabilities of the ionosphere-thermosphere.

The atmospheres of Mars and Venus [PDF]

open access: yes, 1971
Of all the planets which may exist in the Universe, only nine have been studied by man. As a result, one cannot classify planets with the same confidence that one has in classifying stars; there is no theory of planetary evolution comparable in ...

Recent progress on the retrieval and modeling of thermosphere mass density

open access: yes地球与行星物理论评, 2023
The thermosphere is the atmospheric layer extending from about 90 km to nearly 1000 kilometers, which is an important interreaction area between the Sun and the Earth.

Long-term variability of CO2 and O in the Mars upper atmosphere from MRO radio science data [PDF]

open access: yes, 2015
We estimate the annual variability of CO2 and O partial density using approximately 6years of Mars Reconnaissance Orbiter (MRO) radio science data from August 2006 to January 2012, which cover three full Martian years (from the northern hemisphere summer

Vertical damping of gravity waves evaluated from ACS-TGO solar occultation measurements on Mars

open access: yesFrontiers in Astronomy and Space Sciences
Amplitudes of gravity waves generated in the lower and denser atmospheric layers grow exponentially with height as they propagate to the upper and thinner atmosphere, where they are reduced by various processes.

New thermosphere neutral mass density and crosswind datasets from CHAMP, GRACE, and GRACE-FO

open access: yesJournal of Space Weather and Space Climate, 2023
We present new neutral mass density and crosswind observations for the CHAMP, GRACE, and GRACE-FO missions, filling the last gaps in our database of accelerometer-derived thermosphere observations.

Upper atmospheres and ionospheres of planets and satellites

open access: yes, 2017
The upper atmospheres of the planets and their satellites are more directly exposed to sunlight and solar wind particles than the surface or the deeper atmospheric layers.
