Ferric Chloride: The Venusian Unknown UV Absorber?

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Near‐ultraviolet imaging of the planet Venus reveals inhomogeneous absorption features in the otherwise bright clouds. This absorption has been studied for nearly 100 years, but identification of the near‐UV absorber remains one of the largest open questions in Venusian research.

Correlation of High‐Latitude Scintillation With Auroral Precipitation: Case Studies Using GNSS Radio Occultation Data From PlanetiQ

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.

On the Origin of Summer Sporadic E Periodicities at Midlatitudes

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Summertime midlatitude sporadic E (Es) layers exhibit daily periodicities whose underlying physical causes remain to be fully identified. We investigate the origin of these periodicities by analyzing an 11‐year data set (2007–2017) comprising ionosonde measurements, FORMOSAT‐3/COSMIC radio occultation (RO) observations, and WACCM‐X neutral ...

Validation of Global Ionospheric Specification (GIS) Electron Density Measurements During Solar Minimum to Solar Maximum Under Quiet and Disturbed Geomagnetic Conditions

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Global Ionospheric Specification (GIS) three‐dimensional electron density profiles constructed by assimilating the line‐of‐sight total electron content (TEC) from global navigation satellite system (GNSS) radio occultation (RO) measurements by FORMOSAT‐7/COSMIC‐2 (F7/C2) and ground‐based receiver network from international GNSS service ...

Solar eclipse

Image shows a solar eclipse. This was the only solar eclipse visible from Fort Worth in 1951. The moon appears between the earth and the sun, covering 34 percent of the sun\u27s diameter at its peak around 4:40 p.m.

Quasi 6‐Day Wave Variability in the Thermosphere and Ionosphere: Observations and Modeling

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Satellite observations of the upper mesosphere and lower thermosphere from TIMED‐SABER and ICON‐MIGHTI reveal a clear Quasi 6‐Day Wave (Q6DW) event in the winds and temperatures in this region. This Q6DW event persists across multiple data sets throughout the middle‐to‐upper thermosphere and the F‐region ionosphere, including GOLD disk ...

Variation of Venusian Gravity Wave Absolute Momentum Fluxes and Drag as Retrieved From the Akatsuki Mission

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Using temperature retrievals from Akatsuki radio occultation measurements, we characterize gravity wave activity as a function of vertical wavenumber and altitude. For the first time, we estimate the absolute horizontal momentum fluxes and the magnitude of the gravity wave drag (i.e., wave acceleration), assuming a horizontal wavelength of 300

Orbital Control of Reticulofenestra (Calcareous Nannofossils) Assemblages During the Early Pliocene

Paleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Orbital changes have shaped Earth's climate system and influenced the evolution and spatial distribution of marine plankton, including coccolithophores. Some studies have assessed eccentricity's impact on the diversity and morphological evolution of Noelaerhabdaceae taxa during the Quaternary.
