Investigation on the Coherent Component of SHARAD Surface Echo and Surface Roughness: Scaling Behavior and Influence of Hurst Exponent

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The radar surface echo can be separated into coherent and incoherent components by statistical approaches, and the coherent component can be described by a backscattering model related to the RMS height. According to backscattering models for fractal surfaces, the coherent power in decibels decreases with RMS height on a scale independent of ...

Deep Learning Eliminates Massive Dust Storms from Images of Tianwen-1

, 2022
Abstract Dust storms may remarkably degrade the imaging quality of Martian orbiters and delay the progress of mapping the global topography and geomorphology. To address this issue, this paper presents an approach that reuses the image dehazing knowledge obtained on Earth to resolve the dust-removal problem on Mars. In this approach, we collect

Research on internal gravity waves in the Martian atmosphere based on Tianwen-1 and Mars Global Surveyor occultation data

Earth and Planetary Physics
Internal gravity waves (IGWs) are critical in driving Martian atmospheric motion and phenomena. This study investigates Martian IGWs by using high-resolution data from China’s Tianwen-1 mission and the National Aeronautics and Space Administration’s Mars

Joint Observation of a Series of Magnetic Holes by Tianwen-1 and MAVEN on Mars

The Astrophysical Journal
Magnetic holes (MHs) are transient magnetic structures responsible for energy conversion in space plasma. Using single-spacecraft measurements from Mars Atmosphere and Volatile EvolutioN (MAVEN), the existence of MHs on Mars has been confirmed.

Martian atmosphere sputtering escape generated by penetrating hydrogen energetic neutral atoms

Earth and Planetary Physics
Atmospheric escape plays a critical role in shaping the long-term climate evolution of Mars. Among the various escape mechanisms, energetic neutral atoms (ENAs) generated through charge exchange between solar wind ions and exospheric neutrals serve as an

Rapid Response of Martian Magnetotail to Solar Wind Disturbance: Tianwen‐1 and MAVEN Joint Observations

Geophysical Research Letters
The Martian magnetotail is largely controlled by the solar wind (SW) and is modulated by variations in the upstream drivers. However, due to the limitations of single‐spacecraft observations, the effects of SW variations on the Martian magnetotail have ...
