Space Weather, Volume 24, Issue 9, September 2026.Abstract This study presents a survey of high‐latitude ionospheric scintillation using GNSS radio occultation (RO) data from the PlanetiQ satellite. The analysis examines 483 high‐latitude RO tracks between January and May 2023, with 371 tracks exhibiting scintillation events.

Interferometric Synthetic Aperture Radar (InSAR) for Monitoring Seasonal Snow
Water Resources Research, Volume 62, Issue 9, September 2026.Abstract Interferometric Synthetic Aperture Radar (InSAR) offers a potential pathway for measuring seasonal snow water equivalent (SWE) and snow depth at spatial and temporal scales needed for basin‐scale hydrology. First proposed for seasonal snow more than 25 years ago, InSAR uses repeat‐pass radar phase differences to estimate changes in SWE or ...

Global Circulation of Martian Ionospheric Currents Revealed by Magnetometer Data
AGU Advances, Volume 7, Issue 6, September 2026.Abstract In the dynamo region of the Martian ionosphere, a large‐scale current is generated by charge separation: ions collide with neutrals while electrons preferentially gyrate around local magnetic field lines. Using MAVEN magnetometer data and a physics‐informed neural network constrained by Ampère's law and Gauss's law for magnetism (the Neural ...

Martian ionospheric response during the May 2024 solar superstorm
Nature CommunicationsSolar energetic events can have considerable effects on planetary ionospheres. However, the erratic nature of these solar energetic events make observations difficult.

Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract Radiative transfer (RT) models typically solve the radiative transfer equation separately in either the atmosphere or the ocean, limiting accuracy across the atmosphere‐ocean interface. Here, we employ a coupled scalar discrete ordinate RT model to examine methods for the input of measured inherent optical properties (IOPs) of oceanic ...

Biases and Uncertainties in Radiosonde‐Based Precipitable Water Vapor
Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract Precipitable water vapor (PWV) plays an important role in weather and climate phenomena. Accurate PWV measurements based on radiosonde observations are essential for assessing remote‐sensing measurements and long‐term trends. This study examines the performance of PWV algorithms, including their intrinsic biases and their sensitivity to ...

Statistical properties of hot flow anomalies around Mars
Earth and Planetary PhysicsHot flow anomalies (HFAs) are not only a terrestrial phenomenon, but also a solar-system-wide phenomenon, one that can cause significant perturbations in planetary magnetospheres and ionospheres.
