Statistical Downscaling of the Bulk and Tail of Simulated Precipitations

Environmetrics, Volume 37, Issue 2, March 2026.
ABSTRACT Intense precipitation events are projected to become more frequent and severe in the future. Impact studies analyzing these changes typically rely on simulated precipitation data generated by climate models. However, these simulated datasets often exhibit biases and require post‐processing before they can be effectively used in impact studies.

Phase‐Space Synchronization Driven by Moon‐Magnetosphere Coupling in Gas Giants

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We present a new theoretical framework to describe the rapid and spatially localized loss of energetic particles in planetary radiation belts, focusing on interactions between gas giant magnetospheres and their moons. Observations show that flux depletions—known as microsignatures—often refill on timescales comparable to a single drift period,

Earth-based Stellar Occultation Predictions for Jupiter, Saturn, Uranus, Neptune, Titan, and Triton: 2023–2050

The Planetary Science Journal, 2023
In support of studies of decadal-timescale evolution of outer solar system atmospheres and ring systems, we present detailed Earth-based stellar occultation predictions for Jupiter, Saturn, Uranus, Neptune, Titan, and Triton for 2023–2050,

JWST/NIRSpec Reveals the Atmospheric Driver of Saturn's Variable Magnetospheric Rotation Rate

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Past measurements of Saturn's upper atmosphere have allowed only a broad scale view of the temperature and ion density structures within the auroral region. However, Saturn's auroral currents include a planetary period current component that is produced by neutral atmospheric flows.

Dynamics of the giant planets of the solar system in the gaseous proto-planetary disk and relationship to the current orbital architecture [PDF]

, 2007
We study the orbital evolution of the 4 giant planets of our solar system in a gas disk. Our investigation extends the previous works by Masset and Snellgrove (2001) and Morbidelli and Crida (2007, MC07), which focussed on the dynamics of the Jupiter ...

JWST Discovers the Vertical Structure of Uranus' Ionosphere

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract On 19 January 2025, the James Webb Space Telescope (JWST) program # $\mathrm{\#}$5073 observed Uranus for almost a full rotation with NIRSpec. We present the first ever vertical ionospheric profiles of H3+ ${\mathrm{H}}_{3}^{+}$ temperature, volumetric density and total emission.

Probing methane in Uranus’ upper stratosphere using HST observations of the 1280 Å Raman feature

Astronomy & Astrophysics
We analysed far-ultraviolet (FUV) spectra of Uranus obtained by the HST STIS and COS instruments in 2012 and 2014, respectively, to determine the brightness of Raman-scattered Lyman-alpha (Lyα) emissions centred at 1280 Å (hereafter, the Raman feature ...

What do we Really Know about Uranus and Neptune?

, 2012
The internal structures and compositions of Uranus and Neptune are not well constrained due to the uncertainty in rotation period and flattening, as well as the relatively large error bars on the gravitational coefficients.
