Kernel‐Based Estimation of Stratospheric Aerosol Radiative Effects From Volcanic and Wildfire Events

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract To facilitate the quantification of the stratospheric aerosol direct radiative effect (ARE), this study develops a suite of aerosol kernels based on Modern‐Era Retrospective Analysis for Research and Applications, Version 2 reanalysis data. The kernels comprise a five‐dimensional data set that includes latitude, longitude, time, wavelength ...

An Analytical Model of the Lifecycle of Tropical Anvil Cloud Radiative Effects

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Satellite observations and numerical simulations show that the small net Cloud Radiative Effect (CRE) of tropical anvil clouds results from a near‐cancellation between large but opposing longwave (LW) and shortwave (SW) components over the cloud's lifecycle.

Mitigation of tropospheric delay induced errors in TS-InSAR ground deformation monitoring

International Journal of Digital Earth
Interferometric Synthetic Aperture Radar (InSAR) is capable of detecting crust deformation. However, the accuracy is limited by spatiotemporal changes in the lower troposphere.

Experimental Evidence of Giant Electron - Gamma Bursts Generated by Extensive Atmospheric Showers in Thunderclouds

, 2004
The existence of a new phenomena - giant electron-gamma bursts is established. The bursts are generated in thunderclouds as a result of the combined action of runaway breakdown and extensive atmosphere showers (RB-EAS).

Solar Soft X‐Ray Proxy Derived From Observed Auger Photoelectrons by MGS and a 1999–2006 Flare Catalog at Mars

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract This study uses a novel approach to infer the solar soft X‐ray (SXR) irradiance from Auger photoelectron fluxes. Solar SXR irradiance is highly variable, particularly during solar flares. Solar SXR photons at ∼< ${\sim} < $2.5 nm produce oxygen Auger photoelectrons by photoionizing atmospheric constituents. More specifically, we derive the fit

Micro-Arcsecond Radio Astrometry

, 2013
Astrometry provides the foundation for astrophysics. Accurate positions are required for the association of sources detected at different times or wavelengths, and distances are essential to estimate the size, luminosity, mass, and ages of most objects ...

The Influence of Interactive Sea Surface Temperatures on Self‐Aggregation in Channel Domain Radiative‐Convective Equilibrium

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Convective self‐aggregation describes the spontaneous organization of convection that occurs in radiative‐convective equilibrium (RCE) simulations. Here, we conduct RCE simulations coupled to 2‐ and 20‐m slab ocean models in a 3D channel domain to assess the influence of interactive sea surface temperatures (SST) on self‐aggregation.

Atmospheric limitations to clock synchronization at microwave frequencies [PDF]

Clock synchronization schemes utilizing microwave signals that pass through the Earth's atmosphere are ultimately limited by our ability to correct for the variable delay imposed by the atmosphere.

An Evaluation of the Accuracy of Real-Time Zenith Total Delay Estimates

, 2013
The continuous evolution of Global Navigation Satellite Systems (GNSS) meteorology has lead to an increased use of associated observations for operational meteorology worldwide. In order to enhance short-term weather forecasts meteorological institutions use modern low-latency Numerical Weather Prediction (NWP) models which assimilate GNSS-derived ...
