Quantifying the Lifespan of 3D Flood Structures: Unlocking the Potential of Flood Detention Areas for Enhanced Flood Control in China

Water Resources Research, Volume 61, Issue 11, November 2025.
Abstract The escalating frequency and magnitude of floods pose significant challenges to traditional flood control measures with fixed defense capacities, such as levees, dams, and reservoirs. Flood Detention Areas (FDAs) have been widely implemented in many countries as solutions to extreme flood events, functioning by temporarily holding excess ...

Asymmetry of Cyclonic Sea Surface Wind and Wave Observed by SAR

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract CyclObs‐derived wind and SWH field are extracted from over 600 dual‐polarized Sentinel‐1 (S‐1) images of around 300 tropical cyclones (TCs) over the past eight years to investigate asymmetry of wind and wave fields during TCs. Fetch analysis and machine learning technique, eXtreme Gradient Boosting (XGBoost), is used to establish a ...

Enhanced Quantification of Global Carbon Emitters Using Collocated OCO‐3 CO2 and NO2 Observations From Twin Polar‐Orbiting Satellites

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract Satellite‐based estimates of fossil fuel carbon dioxide (FFCO2) emissions are crucial for global stocktaking but are limited by sparse coverage. As nitrogen dioxide (NO2) observations can enhance CO2 emission estimates, we use NO2 observations from twin polar‐orbiting satellites (GaoFen‐5B and DaQi‐1) to constrain carbon emission estimates ...

Comprehensive Analysis of Bias in TEMPO NO2 Column Densities Through Pandora Observations

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 15, 16 August 2025.
Abstract Tropospheric Emissions: Monitoring of Pollution (TEMPO) is the first geostationary satellite instrument to monitor air pollutants across North America. This study uses Pandora observations to analyze the bias in TEMPO Level‐3 total column density of NO2 (TOTNO2) from August 2023 to December 2024.

A Flash Flood Numerical Modeling and Forecasting Tool in Mountainous Small Catchments Based on a 2‐D Hydrodynamic Model

Earth and Space Science, Volume 12, Issue 7, July 2025.
Abstract The forecasting and early warning of flash floods in mountainous areas are extremely challenging. Here, we establish an integrated model of Baseflow‐Rainfall‐Interception‐Flood (BRIF) to support efficient numerical modeling and potential forecasting of flash flood in future.
