Concurrent Variations in Air–Sea Heat Fluxes and Sea Ice Extensions Under Cold‐Air Outbreaks: The First Joint Buoy–Cruise Observational Results in the Bohai Sea

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The air–sea interface near seasonal ice edges notably regulates the regional climate but remains poorly understood. We present the first coordinated buoy–cruise measurements in the Bohai Sea—the world's lowest‐latitude seasonal ice zone—during the winter of 2024–2025.

Correction of Non‐Geophysical Errors in SAR Doppler Shift for Ocean Surface Current Retrieval

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract Synthetic aperture radar (SAR) data contains Doppler information on ocean surface movement, and the Doppler centroid anomaly (DCA) can be used to quantitatively retrieve ocean surface currents in the line‐of‐sight of radar. However, non‐geophysical errors (NGE) in Doppler information significantly affect retrieval accuracy. Generally, existing

Exploring the Links Between Variations in Snow Cover Area and Climatic Variables Across the Upper Indus Basin Under a Changing Climate

International Journal of Climatology, Volume 46, Issue 2, February 2026.
Google Earth Engine was utilised to assess snow cover area (SCA) across eight Upper Indus Basin (UIB) subbasins, employing ARIMA for prediction and comparing MODIS datasets using Dunn's test. Spatiotemporal changes were analysed using MK, Sen's slope, and other statistical tests.
