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 ...

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.

The Potential of Hydrogeodesy to Address Water‐Related and Sustainability Challenges

Water Resources Research, Volume 60, Issue 11, November 2024.
Abstract Increasing climatic and human pressures are changing the world's water resources and hydrological processes at unprecedented rates. Understanding these changes requires comprehensive monitoring of water resources. Hydrogeodesy, the science that measures the Earth's solid and aquatic surfaces, gravity field, and their changes over time ...

Upscaling Land Surface Fluxes Through Hyper Resolution Remote Sensing in Space, Time, and the Spectrum

Journal of Geophysical Research: Biogeosciences, Volume 129, Issue 10, October 2024.
Abstract Numerous efforts to measure land surface fluxes, from leaf to canopy scales, have significantly advanced the field of biogeoscience. However, upscaling these estimates to larger spatial and temporal scales remains a challenge. Recent advancements in remote sensing provide new opportunities to bridge these gaps in upscaling efforts.

Global Observations of Geomagnetically Induced Currents Caused by an Extremely Intense Density Pulse During a Coronal Mass Ejection

Space Weather, Volume 22, Issue 10, October 2024.
Abstract A variety of magnetosphere‐ionosphere current systems and waves have been linked to geomagnetic disturbance (GMD) and geomagnetically induced currents (GIC). However, since many location‐specific factors control GMD and GIC intensity, it is often unclear what mechanisms generate the largest GMD and GIC in different locations.

DSM Quality of Korean Satellite KOMPSAT-3 in Comparison to AW3D30 and Sentinel-1A in Respect of Airborne Laser Scanning

KSCE Journal of Civil Engineering, 2019
With significant technological improvements on earth observation instruments, three dimensional space-borne remote sensing data became indispensable for modelling large areas and continents. To acquire high resolution 3D earth data, actual optical and synthetic aperture radar (SAR) satellite missions are launched frequently.
