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.

A markovian approach to unsupervised change detection with multiresolution and multimodality SAR data [PDF]

open access: yes, 2018
In the framework of synthetic aperture radar (SAR) systems, current satellite missions make it possible to acquire images at very high and multiple spatial resolutions with short revisit times. This scenario conveys a remarkable potential in applications

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

open access: yesWater 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 ...
