A High-Precision Frequency Synchronization Method Based on a Novel Geostationary Communication Satellite Phase-Locked Transponder

Remote Sensing
Equipping satellites with a series of high-precision frequency references is essential; however, even advanced active hydrogen masers can often be too heavy and expensive for the current satellite payload constraints.

Cold Pool Formation Over the Taiwan Bank Driven by Shoaling Internal Tides

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract Cold, saline, and chlorophyll‐rich surface waters are frequently observed over the Taiwan Bank in the southern Taiwan Strait, forming a distinct feature referred to as the Green–Cold Pool (GCP). Despite its ecological importance, the physical mechanisms sustaining this cold pool remain unclear.

Distinguishing Active Box-Wing and Cylindrical Geostationary Satellites using IR Photometry with NASA’s WISE Spacecraft

, 2017
Over 860 observations of 245 box-wing (BW) and 18 cylindrical (C) active geostationary satellites (GEOsats) have been extracted from the thousands of resident space objects (RSOs) serendipitously detected by NASA’s Wide-field Infrared Survey Explorer ...

A Net CO2 Sink in the Korea Strait and East/Japan Sea Revealed by Direct Eddy Covariance Measurements

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract The Korea Strait (KS) and East/Japan Sea (EJS), Kuroshio‐influenced regions of the northwestern Pacific, are important yet still poorly constrained components of the regional carbon budget. Air‐sea carbon dioxide (CO2) fluxes in KS and EJS were quantified using direct eddy covariance measurements collected during seasonal cruises between 2023 ...

Machine Learning‐Based Turbulence Intensity Estimation Near Convective Clouds in East Asia Using GK‐2A Satellite Observations

Geophysical Research Letters
The detection of atmospheric turbulence, particularly near deep convection, are essential for flight safety and efficiency. Geostationary satellites provide continuous coverage where radar is unavailable, but their lack of vertical information limits ...

Physically Consistent Synthesis of Tropical Cyclone Microwave Brightness Temperatures From Geostationary Infrared Observations

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Analyzing the evolution of Tropical Cyclones (TCs) is critical for understanding their structure and intensity, but it has been limited by observational constraints. Spaceborne passive microwave (PMW) observations can penetrate both non‐precipitating and precipitating clouds and provide information on the vertical distribution of hydrometeors ...

Solar Energetic Particle Prediction in the Inner Heliosphere Using Deep Learning and PSP/IS⊙IS Data

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Solar events, such as coronal mass ejections and solar flares, accelerate large numbers of energetic charged particles, producing solar energetic particle (SEP) events that can harm astronauts, damage satellites, and potentially damage infrastructure on Earth.
