Vicarious calibration of GOCI for the SeaDAS ocean color retrieval
International Journal of Remote Sensing, 2019 A key on-orbit calibration step for satellite remote sensing of ocean color is the vicarious calibration. This establishes the final gains for each spectral band on the sensor that minimize bias in the retrieved ocean color signal. The vicarious calibration is specific to the instrument and the atmospheric correction algorithm.

Algorithm to estimate daily PAR at the ocean surface from GOCI data: description and evaluation
Frontiers in Marine Science, 2022 Photosynthetically available radiation (PAR) reaching the ocean surface controls phytoplankton growth, primary productivity, and evolution within marine ecosystems. Therefore, accurate daily PAR estimates are important for a broad range of marine biology

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 ...

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 Modulation Transfer Function Compensation for the Geostationary Ocean Color Imager (GOCI) Based on the Wiener Filter [PDF]
Journal of Astronomy and Space Sciences, 2013 The modulation transfer function (MTF) is a widely used indicator in assessments of remote-sensing image quality. This MTF method is also used to restore information to a standard value to compensate for image degradation caused by atmospheric or ...
