Comparative analysis of GOCI ocean color products. [PDF]

Sensors (Basel), 2015
The Geostationary Ocean Color Imager (GOCI) is the first geostationary ocean color sensor in orbit that provides bio-optical properties from coastal and open waters around the Korean Peninsula at unprecedented temporal resolution. In this study, we compare the normalized water-leaving radiance (nLw) products generated by the Naval Research Laboratory ...

A MULTI-TEMPORAL APPROACH FOR DETECTING SNOW COVER AREA USING GEOSTATIONARY IMAGERY DATA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
In this study, we attempt to detect snow cover area using multi-temporal geostationary satellite imagery based on the difference of spectral and temporal characteristics between snow and clouds. The snow detection method is based on sequential processing

GOCI data processing and ocean applications [PDF]

Ocean Science Journal, 2012
GOCI, the world’s first geostationary ocean color sensor, has been developed with the purpose of monitoring the marine environment and providing a quick and timely warning of marine dangers. It takes eight times a day the images of the Northeast Asian region while the polar orbiters have only a 2-3 day revisit occasion.

Triboelectric Nanogenerators for Marine Applications: Recent Advances in Energy Harvesting, Monitoring, and Self‐Powered Equipment

Advanced Materials Technologies, Volume 8, Issue 21, November 10, 2023., 2023
This paper reviews how Triboelectric Nanogenerators (TENGs) can be used for marine applications. TENGs are devices that convert mechanical energy into electrical energy. This review discusses how TENGs can harvest energy, monitor, forecast, and connect with Internet of Things (IoT) in the marine environment.

Surf, Turf, and Above the Earth: Unmet Needs for Coastal Air Quality Science in the Planetary Boundary Layer (PBL)

Earth's Future, Volume 11, Issue 6, June 2023., 2023
Abstract Coastal areas are some of the most densely populated and economically important regions in the world. As such, protecting the health of the human population and ecosystems at the coastal interface and understanding the impacts of environmental stressors such as air pollutants provides wide‐ranging benefits.
