Preliminary Validation of Thermosphere Observations from the TOLEOS Project [PDF]

, 2022
OBSERVATIONS of upper atmospheric neutral mass density (NMD) and wind are critical to understand the coupling mechanisms between Earth’s ionosphere, thermosphere, and magnetosphere.

A Reduced Dimensional Emulator for Forecasting Equatorial Spread F

Space Weather, Volume 24, Issue 6, June 2026.
Abstract A machine learning emulator has been developed to efficiently reproduce electron densities from a three‐dimensional, data‐driven, regional simulation of postsunset ionospheric irregularities associated with equatorial spread F (ESF). The simulation has previously been shown to produce accurate ESF conditions observed at the Jicamarca Radio ...

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

Frontiers 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.

Advancing Heliophysics and Space Weather Modeling Through Open Science

Space Weather, Volume 24, Issue 6, June 2026.
Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

On the variations of the thermospheric structure [PDF]

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1965
Abstract The paper discusses the properties of the different effects which have been found to occur in the thermosphere and some conclusions which can be drawn with regard to the physics of the thermosphere. In the discussion of the diurnal variation the emphasis is on the behaviour of the diurnal amplitude in density during the solar

Dynamics of High‐Latitude Energy Conversion in the Upper Thermosphere Based on 9‐Year Measurements From FPI and Dynasonde in Tromsø, Norway

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract This study highlights the need to re‐evaluate energy transfer in the upper thermosphere at high latitudes through analysis of 9‐year measurements of neutral wind (u) from a Fabry‐Perot interferometer and ion velocity (v) from a Dynasonde in Tromsø, Norway.

A three dimensional model of the Venusian thermosphere with superrotation

, 1986
An improved three dimensional spectral model of the thermosphere of Venus is described. The model solves the Navier-Stokes equations and includes nonlinear effects for an arbitrary number of atmospheric species.
