Convective Biases in the US DOE Global Storm‐Resolving Model: Insights From Regionally Refined Simulations During the CACTI Campaign

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Accurately simulating convective processes in complex terrain remains a critical challenge for global storm‐resolving models (GSRMs). This study systematically evaluates moist convective biases in the Regionally Refined Mesh configuration of the U.S.

Processes Driving Drift‐Ice Evolution and Its Interaction With the Oceanic and Atmospheric Boundary Layers

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Sea ice is a crucial component of polar climate systems and is undergoing substantial changes in both hemispheres due to evolving climatic conditions. Arctic sea ice is transitioning from perennial to seasonal cover, and the Southern Ocean sea ice is exhibiting recent minima and enhanced seasonality.

PPP‐RTK Atmospheric Correction Generation and Service Applicability: A Case Study During Typhoon Saola and Moderate Geomagnetic Disturbances in Hong Kong

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Complex space weather, such as typhoons and solar activity, can cause heavy rainfall and ionospheric disturbances, affecting the quality of Global Navigation Satellite System (GNSS) signals. Among GNSS positioning techniques, Precise Point Positioning Real‐time Kinematic (PPP‐RTK) uses atmospheric corrections and bias products to achieve fast ...

Establishment of a Real-Time Local Tropospheric Fusion Model

Remote Sensing, 2019
The tropospheric delay is one major error source affecting the precise positioning provided by the global navigation satellite system (GNSS). This error occurs because the GNSS signals are refracted while travelling through the troposphere layer ...

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.
