Origin of Late Noachian‐Early Hesperian Valley Networks on Mars: Insights From Landform Evolution and Ice Sheet Modeling
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract
Dendritic valley networks on Mars have been cited as evidence for a warm and wet Noachian Mars, permitting rainfall precipitation and surface runoff. However, the climatic conditions required to sustain rainfall on early Mars remain debated.K. R. Karpenko, J. L. Fastook, J. W. Head, A. D. Howard, C. I. Fassett, J. L. Dickson, K. E. Scanlon, B. D.

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract
Venus is home to vivid sulfur chemistry, with SO2 ${\text{SO}}_{2}$ as the major sulfur gas species and a global cloud layer between 47 and 70 km composed of H2SO4 ${\mathrm{H}}_{2}{\text{SO}}_{4}$ and H2 ${\mathrm{H}}_{2}$O. The chemistry in the clouds has been extensively studied with 1D models, but none is able to reproduce the three orders Maxence Lefèvre, Franck Lefèvre, Anni Määttänen, Robert Skog, Benjamin Frandsen, Aurélien Stolzenbach, Ashwin Braude +6 morewiley +1 more sourceSaponite Bearing Material Excavated During the Formation of a Recent 25‐m‐Diameter Impact Crater in Southeastern Arabia Terra on Mars
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract
Mars Reconnaissance Orbiter's Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), Context Imager (CTX), and High Resolution Imaging Science Experiment observations were analyzed for a 25‐m‐wide impact crater and associated ejecta deposits located in the dust‐covered Arabia Terra region.R.

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract
On Mars, erosional‐depositional landforms named gullies provide natural experiments for studying the topographic signature of the processes that act on hillslope evolution. High‐resolution topographic data were used to quantitatively compare the steepness of opposing walls in gully alcoves incised into ice‐rich slopeside mantling deposits.A. Noblet, G. R. Osinski, S. J.

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.Abstract
The launch of the Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission in 2023 marked a new era in air quality monitoring by providing high‐frequency, geostationary observations of column NO2 across most of North America. In this study, we present the first implementation of a TEMPO NO2 data assimilation system using the Joint ...Maryam Abdi‐Oskouei, Jérôme Barré, Shih‐Wei Wei, Sarah Lu, Ashley Griffin, Clementine Hardy Gas, Francois Hebert, Stephen Herbener, Eric Lingerfelt, Evan Parker, Christian Sampson, Steve Vahl, Fabio Diniz, Ben Johnson, Cheng Dang, Yannick Tremolet, Benjamin Ruston, Viral Shah, Emma Knowland, Ricardo Todling, Ronald Gelaro, Caroline Nowlan, Gonzalo Gonzalez Abad, Xiong Liu, Brian McDonald, Kristen Zuraski, Jeff Peischl, Caroline Womack, Laura Judd, Thomas Hanisco, Benjamin Menetrier, Cory Martin, Daniel Holdaway, Anna Shlyaeva, Dom Heinzeller, Steven Pawson, Thomas Auligne +36 morewiley +1 more sourceA High‐Efficiency Multivariable TEC‐SOFTS Model for Ionospheric TEC Prediction: Validation Over China Area During Low and High Solar Activity Periods
Space Weather, Volume 24, Issue 5, May 2026.Abstract
The ionospheric Total Electron Content (TEC) is a key parameter for characterizing the ionospheric properties. In this study, an efficient multivariable time series prediction model, TEC‐Series Core Fusion and efficient multivariable time series (TEC‐SOFTS), was constructed by combining multiple geomagnetic and solar activity indices ...Chen Chen, Ling Huang, Wenwen Li, Dezhong Chen, Hongping Zhang, Yidong Lou, Lv Zhou +6 morewiley +1 more sourceA laboratory astrophysics problem
, 2020 Emission lines of singly charged ions populate many astrophysical spectra. However, the interpretation of the line intensities (usually line ratios) often depends on the transition rates of the decays of very long-lived low-lying levels. For example, the line ratio of two electric-dipole forbidden transitions in the \(3s^{2} 3p^{3}\) ground ...openaire +1 more sourceStorm‐Time Dst Forecast: An Innovative Approach
Space Weather, Volume 24, Issue 5, May 2026.Abstract
One of the most persistent challenges in the space weather field is predicting the storm‐time response of the geospace without knowing the predicted drivers in the solar wind. Here, a new pattern recognition algorithm is developed to predict storm‐time Dst index from 1 hr to ∼4.5 days into the future. Storm‐time Dst patterns (or reference Dst) Yongliang Zhang, Larry J.
