Nitric Oxide Intensification Associated With STEVE: TIMED/SABER‐REGO Observations and Comparison With GITM Simulation

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract Strong Thermal Emission Velocity Enhancement (STEVE) is a nightsky optical phenomenon of great research interest in recent years. STEVE is recognized to be co‐located with a latitudinally narrow channel of fast westward ion drifts, also known as “subauroral ion drifts” (SAID).

WACCM‐RR: A Regionally‐Refined Version of the Whole Atmosphere Community Climate Model

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract We introduce the Whole Atmosphere Community Climate Model with Regional Refinement (WACCM‐RR) and study the impact of directly resolving gravity waves (GWs) in the mesosphere and lower thermosphere (MLT; 70–140 km). Two simulations of 2010 are compared: “Non‐RR” is a standard WACCM case with a horizontal resolution of ∼1° (111 km) globally ...

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Drivers of F‐Region Ionosphere Tidal Variability Caused by the Madden Julian Oscillation: Separating E‐Region Dynamo and Field‐Aligned Wind Effects

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The Madden–Julian Oscillation (MJO), a recurring intraseasonal (30–96 days) disturbance in the troposphere, strongly influences the E‐region and F‐region ionosphere through its modulation of atmospheric tides. Among these, the diurnal eastward wave number 3 (DE3) tide, driven by MJO‐modulated latent heating, carries MJO signals upward into the

Snow Depth on Arctic Sea Ice Retrieval Using a Synergy of Sentinel‐3's Active and Passive Microwave Instruments

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Snow depth remains one of the largest sources of uncertainty in satellite‐derived sea ice thickness (SIT). Here, we introduce the novel Nadir Radiometer and Radar Synergy (NaRRS) method that combines data from Sentinel‐3's Microwave Radiometer (MWR) and Synthetic Aperture Radar Altimeter (SRAL) to retrieve Arctic snow depth on sea ice.

Assessment of Trace Element Daily Intake Based on Consumption Rate of Foodstuffs in Bandung City

open access: yesAtom Indonesia, 2012
Trace elements are required by human body and have a variety role in biochemical functions mostly as catalyst for enzymatic activity in human body. Some trace elements are essential since they are inadequately or not synthesized by human body.

Microsat‐2B Radiance Assimilation in the NCMRWF Global Forecasting System: Quantification of Analysis Improvement

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Indian Space Research Organization (ISRO) recently launched the meteorological satellite Microsat‐2B (M2B), which provides high‐resolution atmospheric moisture radiance observations, crucial for improving the predictability of numerical weather prediction (NWP) models.

Nitric Oxide Radiative Relaxation Time: Damping Timescales of Lower Thermospheric Thermal Perturbations

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Nitric oxide (NO) radiative cooling governs much of the energy budget in the Earth's lower thermosphere and damps out temperature perturbations. The radiative relaxation time (RRT), the timescale that defines how efficiently infrared radiation damps out the perturbations to the thermal structure to 1/e of the perturbation's initial value, is ...

A First Look at the Snow/Ice Penetration Effect of SWOT Observations on Water Level of Global Glacial Lakes

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission promises quasi‐global monitoring of glacial lakes, yet the elevation difference arising from its Ka‐band radar penetrating lake snow/ice cover remains unquantified. This poses a challenge to assessing their level changes.
