GEOSPATIAL ANALYSIS USING REMOTE SENSING IMAGES: CASE STUDIES OF ZONGULDAK TEST FIELD [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Inclined topographies are one of the most challenging problems for geospatial analysis of air-borne and space-borne imageries. However, flat areas are mostly misleading to exhibit the real performance.

Quantitative Assessment of GOES 8–15 > ${ >} $0.6 and > ${ >} $4 MeV Radiation Belt Electron Fluxes

Space Weather, Volume 23, Issue 3, March 2025.
Abstract On Geostationary Operational Environmental Satellites (GOES) 8–15 (1996–2020), the Energetic Particle Sensor (EPS) included three integral electron channels, with nominal lower energies of 0.6 MeV (E1), 2 MeV (E2) and 4 MeV (E3). The > ${ >} $2 MeV channel has received more attention than the other two channels, because it is used by the NOAA ...

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

River 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 ...

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

Advances 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

Geophysical 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 ...

Mapping co-seismic surface deformation using high-resolution KOMPSAT-3/3A image correlation for the 2023 Kahramanmaraş earthquakes, Türkiye

Scientific Reports
Large earthquakes commonly generate surface rupture accompanied by both localized on-fault slip and spatially distributed off-fault deformation. Capturing both components is essential for understanding rupture processes and improving earthquake hazard ...

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

Geophysical 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.
