Satellite‐Based Assessment of Methane Emissions From the Darvaza Gas Crater
Abstract Methane is a potent greenhouse gas, and the Darvaza crater in Turkmenistan is a rare, persistent emitter. There are uncertainties regarding its formation date (either 1963 or 1971), fire ignition, and the fire's influence on methane release. Using historical Landsat imagery, we reconstruct the fire history, identifying that combustion began ...

A Deep Learning Enhanced Atmospheric Correction Algorithm for Chinese GF-1 and GF-6 WFV Images
A critical challenge in obtaining atmospheric corrected surface reflectance (SR), which serves as the foundation for diverse applications, lies in the accurate retrieval of aerosol optical properties, particularly Aerosol optical depth (AOD). Due to lack

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
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
