Internal Heat Flux and Energy Imbalance of Uranus

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract With its extreme axial tilt, Uranus' radiant energy budget (REB) and internal heat flux remain among the most intriguing mysteries in our solar system. By combining observations with modeling, we present the global REB over a complete orbital period (1946–2030), revealing significant seasonal variations.

Seasonal CO2 Cycle at the Martian Poles Revealed by Sounding Radar

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Seasonal CO2 frost accumulates and ablates at the Martian poles during night and day, respectively. We report the first robust measurements of polar seasonal change in SHAllow RADar (SHARAD) data, based on calibration of the 16‐year data set.

MAVEN Observations of Metallic Fe+ Distributions in the Martian Ionosphere

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Metallic ions deposited in planetary atmospheres via meteoroid ablation are an invaluable tool for understanding electric fields, atmospheric winds, and minor ion transport. At Mars, metallic ion distributions are poorly understood. We analyze MAVEN/NGIMS Fe+ ${\mathrm{F}\mathrm{e}}^{+}$ distributions in the Martian ionosphere over the period ...

A Predictive Model of the Position of Plasmapause Based on Lunar Phase and Deep Learning Framework

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract The plasmapause position is crucial for understanding magnetospheric dynamics and space weather forecasting. This study pioneers the integration of lunar phase (LP) into plasmapause modeling using two neural network architectures (BP and fully connected neural network) and a large database of 37,869 crossing events from 1977 to 2015.
