Observation of Daily Flood Hazard During the SWOT Cal/Val Orbit

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Flood peaks can develop and recede within a day, making them difficult to capture with satellites with multi‐day revisit intervals. Here, we exploit daily observations during the Calibration and Validation phase of the SWOT mission to examine a short‐lived flood in May 2023 along the Du Gouffre River in Canada. Despite channel widths below 100

Correcting Unwrapping Errors Toward Reliable Rock Glacier Velocity From InSAR Time Series

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Rock Glacier Velocity is an Essential Climate Variable Permafrost Quantity, providing a quantifiable indicator of mountain permafrost evolution. Despite its wide usage, multi‐temporal InSAR often substantially underestimates rock glacier velocities compared to ground‐based measurements, limiting its reliability.

Potential Benefits of Assimilating Phased Array Radar Data for Convective‐Scale Analysis and Prediction of Supercell Storms: A Proof‐of‐Concept OSSE Study

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract This study investigates the impact of phased array radar (PAR) scanning strategies on short‐term convective‐scale analyses and forecasts through an Observing System Simulation Experiment framework. The Weather Research and Forecasting model, coupled with the Data Assimilation Research Testbed ensemble adjustment Kalman filter, is used to ...

Coherent Turbulence Signatures Preceding Warm Rain Events From Collocated Cloud Radar and Wind Profiler Observations Across China

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Warm rain is plagued by a longstanding droplet growth bottleneck, one that turbulence may alleviate by enhancing droplet coalescence in the late condensation phase. Nevertheless, empirical observational support from multiple sites remains scarce. Here, we combine collocated nationwide millimeter cloud radars, radar wind profilers, Himawari‐8/9

Aerosol Retrieval Over Ocean From DPC‐2/GF‐5(02): Using RemoTAP Extended With a 3‐Parameter Ocean Bio‐Optical Model and Comparisons With a 1‐Parameter Model

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Multi‐angle polarimetric instruments (MAPs) enable the retrieval of essential aerosol properties over oceanic regions. MAPs retrieval algorithms commonly use a 1‐parameter ocean bio‐optical model (OBM), based on chlorophyll‐a concentration only to represent optical properties over open waters (case‐1), whereas the coastal water (mixture of ...
