KOMPSAT Beta Test: Ocean Applications Using KOMPSAT Satellite Data

open access: yes, 2016
For monitoring of coastal erosion in the East Sea, one KOMPSAT-3A data obtained on November 26, 2015 is used. This data is applied at the auto-extraction algorithm of coastline which was developed using three KOMPSAT-2 data previously. Another KOMPSAT-3A

Cascading consequences of structural interventions in a tropical wandering gravel‐bed river

open access: yesRiver Research and Applications, Volume 41, Issue 1, Page 120-137, January 2025.
Abstract Riverscapes are often modified and managed through ‘command and control’ structural engineering approaches. These structures not only alter flow and sediment transport patterns but also negatively affect riverscape biodiversity. These impacts are particularly acute for rivers that are characterised by high mobility and wide flow distribution ...

Accuracy Assessment of a Digital Elevation Model Constructed Using the KOMPSAT-5 Dataset

open access: yesRemote Sensing
The Interferometric Synthetic Aperture Radar (InSAR) has significantly advanced in its usage for analyzing surface information such as displacement or elevation. In this study, we evaluated a digital elevation model (DEM) constructed using X-band KOMPSAT-

Impacts of Updated Physics Parameterizations on the Short‐Range Weather Forecast System of the Korea Air Force

open access: yesAdvances in Meteorology, Volume 2025, Issue 1, 2025.
The weather prediction model system of Korea Air Force (KAF), based on the Weather Research and Forecasting (WRF) model, has been operated since 2007. This study incorporates recent physics parameterizations into the KAF‐WRF system and evaluates their impacts on the performance of the system in simulating winter precipitation, fog, and low‐level cloud ...

Near‐Earth Reconnection Contributing to Recovery Phase of Geomagnetic Storm

open access: yesGeophysical Research Letters, Volume 51, Issue 24, 28 December 2024.
Abstract Recent observations show very near‐Earth reconnection (∼8–13RE) could efficiently power the ring current during the main phase of geomagnetic storms, but whether the recovery phase might be contributed remains unclear. During the recovery phase of the May 2024 major geomagnetic storm, intense auroral brightening and geomagnetic disturbances ...

Influence of Atmospheric Slant Path on Geostationary Hyperspectral Infrared Sounder Radiance Simulations

open access: yesGeophysical Research Letters, Volume 51, Issue 23, 16 December 2024.
Abstract Accurately simulating a geostationary hyperspectral infrared sounder is critical for quantitative applications. Traditional radiation simulations of such instruments often overlook the influence of slant observation geometry by using vertical profile assumption, leading to inadequate simulation accuracy.

Surface Observation Probability System of KOMPSAT-3

open access: yes, 2006
The surface observation probability system (SOPS) of the Korea Multi-Purpose Satellite (KOMPSAT) has been developed based on the climatological distribution of cloud coverage and the expected passage of satellite orbit. While the optical camera loaded on
