Coastal sea surface current observation with GOCI imagery

SPIE Proceedings, 2013
Measurements of sea surface currents are important in understanding the dynamic of ocean processes especially in coastal waters, and satellite remote sensing has been used to derive sea surface advective velocities with visible or infrared imagery. Yet satellite remote sensing suffered from lack of high temporal imagery in dynamic coastal waters and ...

A New Normalized Difference Ice Index (NDII) Based on GOCI Imagery for Accurate Sea Ice Extraction: Application in Peter the Great Bay, Sea of Japan

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The rapidly changing sea ice conditions in seasonal ice zones highlight the necessity for effective sea ice monitoring. However, distinguishing between ice and water, particularly in regions with large areas of thin sea ice, remains a challenging task ...

Estimation of aerosol spectral characteristics by GOCI hourly observations

SPIE Proceedings, 2014
This study proposes a method for estimating the spectral characteristics of aerosol scattering using the Korean Geostationary Ocean Color Imager (GOCI). GOCI three-hourly observations around noon are used to separate ocean and aerosol reflectance with the assumption that the aerosol amount changes but that the spectral shape of the aerosol scattering ...

Framework for predicting the spatial distribution of green algae blooms utilizing historical GOCI and MODIS imagery.

Marine Environmental Research
Green algal blooms (GABs) have become a global concern and are particularly serious in the southern Yellow Sea (SYS). Remote sensing (RS) images are the most popular and effective data source for detecting GABs; however, in case of unfavorable weather ...

Horizontal and vertical migration of cyanobacterial blooms in two eutrophic lakes observed from the GOCI satellite.

Water Research, 2023
Under the variations of natural conditions (temperature, wind speed, light, et al.) and self-regulation of buoyancy, cyanobacterial blooms can change rapidly in a short time.

Cloud motion in the GOCI/COMS ocean colour data

International Journal of Remote Sensing, 2016
The Geostationary Ocean Colour Imager GOCI instrument, on Korea’s Communications, Oceans, and Meteorological Satellite COMS, can produce a spectral artefact arising from the motion of clouds – the cloud is spatially shifted and the amount of shift varies by spectral band.
