Improved Tropical Cyclone Wind Estimation Using Dual‐Polarization C‐Band SAR and Machine Learning

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Tropical cyclones (TCs) characterized by extreme wind speeds present severe hazards to human life and infrastructure. Spaceborne synthetic aperture radar (SAR) has emerged as a critical observational tool for TCs, owing to its all‐weather, high‐resolution imaging capabilities.

An Observational and Forecast Study of Super Typhoon Fung‐Wong in 2025 Over the South China Sea

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Super Typhoon Fung‐wong took an unusual track over the western North Pacific and the northeastern part of the South China Sea in the late typhoon season of 2025. This paper summarizes some integrated observations about this super typhoon, including aircraft, dropsonde and wind profiler data.

Seasonal Patterns of the Caribbean Current and Its Influence on the Small Island of Curaçao

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Large‐scale ocean currents exhibit spatial and temporal variability that can influence local circulation patterns, particularly around small islands. Two distinct flow regimes were previously identified around the southern Caribbean island of Curaçao: (a) strong northwestward flow, and (b) cyclonic eddies or low‐energy conditions ...

Ten Years of SeaWinds on QuikSCAT for Snow Applications

Remote Sensing, 2010
The scatterometer SeaWinds on QuikSCAT provided regular measurements at Ku-band from 1999 to 2009. Although it was designed for ocean applications, it has been frequently used for the assessment of seasonal snowmelt patterns aside from other terrestrial ...

An Grided Soil Moisture Profile Data Set Based on an Optimal Land Surface Model With Measured Hydraulic Parameters and Data Assimilation Over the Loess Plateau

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Soil moisture (SM) is a key water source for vegetation, directly determining the success of revegetation efforts in water‐limited regions. However, accurate profile SM data remain lacking for the Chinese Loess Plateau (LP), limiting ecological restoration efforts.
