Spaceborne Far‐Infrared Signal Simulations Over the Antarctic Plateau With Temperature‐Dependent Ice Cloud Optical Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Longwave cloud radiative effects significantly influence variability in global and regional Earth systems. However, there have been very few, if any, measurements of the far‐infrared (FIR) radiation over the polar regions, where about half of the outgoing longwave radiation is in the FIR spectrum. This motivated the Polar Radiant Energy in the

Dominant Biases in Atmospheric Radiative Heating Rates in Global Climate Models

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The Earth's energy budget is fundamental to climate, and its accurate simulations in global climate models (GCMs) are essential for climate projections. While studies have validated energy budget at the top of the atmosphere (TOA) and surface, the layer‐wise atmospheric energy budget remains largely unexplored because of limited observations ...

Role of Shortwave Feedback in Non‐Linear Response to CO2 Forcing in GFDL CM4.0

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Effective climate sensitivity (EffCS) is a key metric for quantifying climate change, yet its uncertainty remains large, primarily due to intermodel differences in cloud feedback. Here, we assess EffCS and climate feedback to an abrupt doubling (2xCO2) and quadrupling (4xCO2) of CO2 over 450 years in GFDL CM4.0. Both runs have comparable EffCS

Sources of ToA estimation error in LoS scenario

, 2010
Time-of-arrival (ToA) estimation technique used with ultra-wideband (UWB) transmission can be used for accurate indoor ranging. In the indoor multipath rich environment, these techniques often suffer from significant inaccuracy in ranging estimation.

Fast Breakdowns Observed in the Initial Leaders of Two Energetic Compact Strokes

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract We have observed 1 fast positive breakdown (FPB) and 20 fast negative breakdowns (FNBs) for the first time in the initial leader of two energetic compact strokes (ECSs) using a broadband interferometer. It was found that the FPB propagated upward over a distance of 30 m with a speed of 1.2×107m/s $1.2\times {10}^{7}\mathrm{m}/\mathrm{s ...

Evaluating the Role of Kernel Choice on Radiative Feedback Estimates

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Radiative feedbacks are important for understanding climate sensitivity, yet estimates vary widely across climate models. Feedbacks are often computed using the radiative kernel technique, which uses pre‐calculated radiative sensitivities (kernels) derived from different models and base states. While much attention has been given to intermodel

Refining the Simulation of Mixed‐Phase Clouds Over Coastal Antarctica With a Tailored Ice Nucleating Particle Parameterization

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Climate models have substantial biases in downwelling shortwave radiation over the Southern Ocean (SO) and Antarctica, primarily due to their inability to accurately represent the frequent occurrence of low‐level mixed‐phase clouds. Building on the evaluation of the Unified Model (UM) Regional Atmosphere and Land version 3 (RAL3), this study ...
