Symmetric Instability in a Boussinesq Fluid on a Rotating Planet

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract Symmetric instability has broad applications in geophysical and planetary fluid dynamics. It plays a crucial role in the formation of mesoscale rainbands at mid‐latitudes on Earth, instability in the ocean's mixed layer, and slantwise convection on gas giants and icy moon oceans.

Deep Space Network Radio Science and Ground‐Based Planetary Radar in the Next Decade

Radio Science, Volume 60, Issue 7, July 2025.
Abstract The Deep Space Network (DSN) has been a core operational element of NASA's crewed and robotic exploration of the Solar System since the early 1960s. The primary role of the DSN has been to acquire telemetry and navigation data, but over the years, its radiometric and radar capabilities have expanded to form a system for obtaining unique ...

Latitudinal Dependence of the Solar Wind During Periods of High and Low Activity Through Interplanetary Scintillation

Space Weather, Volume 23, Issue 7, July 2025.
Abstract We present a study of the solar wind over different periods of the solar cycle, specifically focusing on the minimum between solar cycles 24 and 25, and the active, ascending phase of solar cycle 25. With the use of interplanetary scintillation (IPS) data taken by the Murchison Widefield Array (MWA) from mid‐2019 and early 2023, we have ...

Mapping the Ionosphere Over East Asia Based on Ground‐Based GNSS TEC Data in 2010–2023

Space Weather, Volume 23, Issue 7, July 2025.
Abstract Using total electron content (TEC) data from multiple ground‐based Global Navigation Satellite System (GNSS) receiver networks from 2010 to 2023, we reconstructed ionospheric TEC maps for East Asia. The maps cover longitudes from 70°E to 150°E and latitudes from 20°S to 60°N. The time resolution of reconstructed TEC map was 15 min.

A Method to Retrieve Aeronomic Parameters From Noontime Bottom‐Side Equatorial Ne(h) and Satellite Neutral Density Observations

Space Weather, Volume 23, Issue 7, July 2025.
Abstract A new method has been proposed to retrieve neutral composition ([O] [O2], [N2]), exospheric temperature (Tex), vertical ExB plasma drift, and total solar EUV flux (λ ≤ 1050Å) using Digisonde DPS‐4 daytime bottom‐side (≥200 km) Ne(h) profiles and satellite‐observed neutral density.
