Impacts of the GDS 2018 Global Dust Storm on Martian Ionosphere‐Thermosphere Coupling via Atmospheric Tides

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract In this study, we investigate the ionospheric and thermospheric responses to the 2018 Mars global dust storm (GDS 2018) by examining atmosphere–ionosphere coupling through tidal structures. Using Mars Atmosphere and Volatile EvolutioN Neutral Gas and Ion Mass Spectrometer observations, we analyze tidal amplitudes, phases, and inter‐species ...

Further evidence of long-term thermospheric density change using a new method of satellite ballistic coefficient estimation

, 2011
Building on work from previous studies a strong case is presented for the existence of a long-term density decline in the thermosphere. Using a specially developed orbital propagator to predict satellite orbit evolution, combined with a new and accurate ...

Variation of Venusian Gravity Wave Absolute Momentum Fluxes and Drag as Retrieved From the Akatsuki Mission

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Using temperature retrievals from Akatsuki radio occultation measurements, we characterize gravity wave activity as a function of vertical wavenumber and altitude. For the first time, we estimate the absolute horizontal momentum fluxes and the magnitude of the gravity wave drag (i.e., wave acceleration), assuming a horizontal wavelength of 300

Robust Short‐Term Forecasting of Thermospheric Density and Orbit Prediction Using an Interpretable iTransformer Model

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Accurate short‐term forecasting of thermospheric mass density is crucial for satellite operations. However, achieving high‐precision predictions remains a significant challenge. In this study, we develop an iTransformer framework that forecasts thermospheric density over the next 24 hr using observations from the preceding 24 hr. Using density

The High‐Latitude Workbox for the Ionosphere (HAWK‐I): A New Toolkit for Real‐Time Specification of the Arctic Ionosphere

Space Weather, Volume 24, Issue 9, September 2026.
Abstract The high‐latitude ionosphere exhibits rapid spatial and temporal variability during geomagnetically active periods, creating persistent challenges for accurate nowcasts. The High‐latitude Workbox for the Ionosphere (HAWK‐I) is a real‐time ionosphere nowcast and specification system designed for operational deployment to address these ...

MSIS‐UQ: Calibrated and Enhanced NRLMSIS 2.0 Model With Uncertainty Quantification

Space Weather, 2022
The Mass Spectrometer and Incoherent Scatter radar (MSIS) model family has been developed and improved since the early 1970's. The most recent version of MSIS is the Naval Research Laboratory (NRL) MSIS 2.0 empirical atmospheric model.

The Ionosphere as an Operational Constraint on Space‐Based Solar Power

Space Weather, Volume 24, Issue 9, September 2026.
Abstract This commentary argues that there is an urgent need to develop a scientific consensus on how microwave beams from space‐based solar power (SBSP) satellites will interact with plasma in the ionosphere. Whilst the SBSP concept dates back to the 1970s, it is now gaining traction around the world as a technology that could contribute baseline ...

Acoustic Wave Heating of the Thermosphere [PDF]

, 2001
A numerical model is used to study the dissipation in the thermosphere of upward propagating acoustic waves. Whereas dissipating gravity waves can cool the upper atmosphere through the effects of sensible heat flux divergence, it is found that acoustic ...

The Impact of Polar Vortex Strength on the Longitudinal Structure of the Noontime Mid-Latitude Ionosphere and Thermosphere

Remote Sensing
Ground-based ionospheric, CHAMP/STAR, and GOCE satellite neutral density ρ observations under deep solar minimum conditions were used to find whether there is a dependence of longitudinal variations on polar vortex strength. Ionospheric stations at fixed-
