Roles of Surface Latent Heat Flux and Gravity Waves in Offshore MCS Development in the Coastal Eastern Tropical Pacific

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The eastern tropical Pacific (ETP) coastal region, one of the rainiest places on Earth, is characterized by distinct diurnal offshore rainfall propagation primarily driven by mesoscale convective systems (MCSs). Previous studies have shown that MCS initiation in this region peaks in the early morning, with diurnally generated gravity waves ...

Thermospheric mass density derived in near real time from space debris

Journal of Space Weather and Space Climate
Near-Earth space is becoming increasingly congested. A rapid increase in the number of orbiting objects around Earth underscores the need for accurate tracking and prediction of space objects.

Observations and Simulation of Thermospheric Composition Changes During the 14 October 2023 Solar Eclipse

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract This study presents a full‐period imaging of the thermospheric composition response to the 14 October 2023 annular solar eclipse, combining GOLD (Global‐scale Observations of the Limb and Disk) far‐ultraviolet observations with solar‐irradiance‐driven WACCM‐X (Whole Atmosphere Community Climate Model with thermosphere–ionosphere extension ...

Daytime Ionospheric Density Enhancement Driven by Poleward Neutral Wind Shear Associated With Gravity Waves During the November 2025 Geomagnetic Storm

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The threefold daytime electron density increases, along with strong poleward meridional winds exceeding 200 m/s were captured by Sanya Incoherent Scatter Radar (SYISR) during the geomagnetic storm of 12 November 2025. The great ionospheric enhancements were extending to mid‐latitudes over 40° observed by total electron content (TEC) from ...

Martian Thermospheric Warming Associated With the Planet Encircling Dust Event of 2018

Geophysical Research Letters, 2020
We report the first observations of Martian thermospheric warming associated with the Planet Encircling Dust Event (PEDE) of 2018. We used dayglow observations made by the Imaging Ultraviolet Spectrograph instrument aboard the MAVEN spacecraft to ...

Mars' Ionospheric Response to the Onset and Early Phase of 20 May 2024 Solar Flare

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Solar extreme ultraviolet (EUV, 10–100 nm) and X‐ray (<10 nm) photons are the primary ionization source for the dayside Mars ionosphere. Their fluxes, especially at short wavelengths, increase significantly during solar flares. Among the series of solar flares and solar storms encountered by Earth and Mars in May 2024, one of the strongest ...

Saturn Variable Thermosphere

, 2016
Our knowledge of Saturns neutral thermosphere is far superior to that of the other giant planets due to Cassini Ultraviolet Imaging Spectrograph (UVIS) observations of 15 solar occultations and 26 stellar occultations analyzed to date. These measurements yield H2 as the dominant species with an upper limit on the H mole fraction of 5 %.

Data‐Driven Satellite Drag Modeling Without Dynamic Knowledge of the Atmosphere

Space Weather
Increasing congestion in low Earth orbit (LEO) from new satellite deployments and a growing debris population has made accurate orbital trajectory prediction essential for anticipating and avoiding potential collisions on a regular basis.

Productino of KSR-III Airglow Photometers to Measure MUV Airglows of the Upper Atmosphere Above the Korean Peninsular

Journal of Astronomy and Space Sciences, 2002
We have constructed two flight models of airglow photometer system (AGP) to be onboard Korea Sounding Rocket-III (KSR-III) for detection of MUV dayglow above the Korean peninsular.
