Cross-calibration of GOCI and GOCI-II TOA Radiation Data

, 2022
Degradation of satellite sensor sensitivity may occur due to aging of sensors. Since this affects the accuracy of atmospheric correction and the trend of long-term monitoring of marine environmental variables, it is necessary to continuously update the ...

Contrasting Sea Surface Cooling and Chlorophyll‐a Responses to Typhoon Hinnamnor (2022) Modulated by Oceanic Background Conditions

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract This study investigates the physical and biological responses of the Yellow Sea (YS) and East China Sea (ECS) to Typhoon Hinnamnor (2022), with an extensive 34‐kt wind radius of approximately 430 km, using satellite‐derived sea surface temperature and ocean color data, in situ observations, and ocean analysis data.

Toward GOCI-III Improvement from the Experiences of GOCI-II

, 2023
In this study, we discuss the development direction and requirements for the 3rd Geostationary Ocean Color Imager (GOCI-III) based on experiences with the previous GOCI (June 2010 to March 2021) and GOCI-II (March 2020 to now).

Satellite‐Observed Hourly Chlorophyll Variability Associated With Solar Radiation in China's Marginal Seas

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Understanding sub‐daily variability in phytoplankton proxies is essential for interpreting satellite estimates of ocean productivity in marginal seas. Using high‐frequency observations from the Geostationary Ocean Color Imager (GOCI), we assess daytime (08:00–15:00 local time) hourly surface chlorophyll‐a (Chla) variability across China's ...

Use of GOCI-II images for detection of harmful algal blooms in the East China Sea

Geoscience Letters
The East China Sea (ECS) has experienced severe harmful algal blooms (HABs) that have deleterious ecological effects on marine organisms. Recent studies indicated that deploying of a second geostationary ocean color imager (GOCI-II) can significantly ...

A novel method for distinguishing different algal blooms in the East China Sea via geostationary ocean color satellite observations

Frontiers in Marine Science
IntroductionDinoflagellate and diatom blooms are the most frequent marine ecological disasters in the Yangtze River estuary (YRE) and adjacent areas of the East China Sea (ECS).

Divergent Heat Assessments Across Thermal Stress and Sensation Metrics

Earth's Future, Volume 14, Issue 7, July 2026.
Abstract A large and growing body of literature has indicated potential inconsistencies in heat assessments due to the use of different heat stress indices (HSI). This divergence hinders the emergence of scientific consensus and impairs the development of public policy on a range of topics, including climate change impacts, public health guidance, and ...

Global Fair‐Weather Bias in Remotely Sensed Coastal Suspended Sediment Concentration

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Satellite estimates of suspended‐sediment concentration (SSC) are widely used to understand ecosystem functions and resilience of coastal environments. Yet, they rely largely on fair‐weather observations. Combining continuous in situ time series with multi‐decadal satellite records and reanalysis products, we quantify a systematic fair‐weather

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 ...

On-Orbit Radiometric Calibration and Stability Assessment of the Visible to Near-Infrared Bands of Geostationary Ocean Color Imager-II (GOCI-II)

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
While most previous ocean color missions relied on polar-orbiting satellites, geostationary platforms are gaining attention for their capacity to continuously monitor dynamic coastal ocean. In Northeast Asia, Geostationary Ocean Color Imager-II (GOCI-II)&
