Formation of Continuum Emission Structures Associated With the Aurora

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Recent observations enabled by improvements in geospace remote‐sensing instrumentation have revealed the spatial structure of continuum emissions that appear to be associated with the aurora, but little is known about the formation and drivers of these structures.

Characterization of Mercury's Atomic and Molecular Hydrogen Exosphere and the First Detection of H2 Ions

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract From 1974 to 1975, the Mariner 10 spacecraft studied Mercury's environment during three flybys and detected hydrogen, helium, and possibly atomic oxygen in the exosphere using its ultraviolet spectrometer, but no molecular hydrogen. Based on the sensitivity of the occultation instrument, an upper limit for the H2 ${\mathrm{H}}_{2}$ surface ...

Mesoscale Stationary Features in the Dayside Clouds of Venus

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract We present new detections of mesoscale stationary features, which are interpreted as gravity waves, on the dayside clouds of Venus. These come from an analysis of images from two instruments onboard different spacecrafts: Visible and InfraRed Thermal Imaging Spectrometer—Mapper (VIRTIS‐M) on Venus Express (VEx) and IR2 on Akatsuki.

Multidisciplinary Analyses of Terrestrial Samples Used to Interpret an Inorganic Origin (Anhydrite:Ce3+) for the 304 and 325‐nm Doublet Fluorescence Detected by the Mars 2020 SHERLOC Instrument at Jezero Crater

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Doublet fluorescence at 304 and 325‐nm under deep ultraviolet (DUV) excitation was detected on Mars at Jezero crater by the Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) instrument onboard the Mars 2020 rover Perseverance.

Extending the Atmospheric Radiative Transfer Simulator (ARTS) to Shortwave Radiation

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Atmospheric Radiative Transfer Simulator (ARTS) is an open source general purpose radiative transfer model used for a wide range of applications from remote sensing to the interaction of climate and radiation. In the past, it was confined to the microwave and infrared spectral range, as ARTS could not simulate the interaction of solar ...
