This article presents an innovative technique for remote sensing-based mapping and predicting land degradation in the European frontier regions. The mapping is carried out by geospatial data fusion of relevant biophysica...

Land degradation (LD) is a major barrier toward achieving the Sustainable Development Goals (SDGs), particularly in Sub-Saharan Africa (SSA), due to challenges in national assessments. A comprehensive spatiotemporal anal...

This review addresses the urgent need for scalable, accurate, and reproducible remote sensing solutions following the February 2023 Türkiye earthquakes. It synthesizes the contributions of five peer-reviewed studi...

Terrestrial evaporation ($E$) plays a crucial role in the water, energy, and carbon cycles and modulates climate change through multiple feedback mechanisms. While process-based models estimate $E$ using satellite-derive...

Context. Co-orbital objects, also known as Trojans, are celestial bodies that share a 1:1 mean motion resonance orbit with a planet. Many planets in our Solar System hold Trojans, yet none has been confirmed in exoplanet...

Small near-Earth asteroids (NEAs), diameters < 150 m, represent the most numerous yet one of the least well-understood populations among near-Earth objects, despite their potential hazard. Their rapid fading after discov...

The dipole-dominated magnetic fields of Jupiter and Saturn provide evidence for active dynamos operating within their deep interiors, yet the depth of the convecting dynamo layers remains poorly constrained. While magnet...

Water security in the Gulf Cooperation Council (GCC) is under existential threat from aquifer depletion, intensifying climate extremes, and escalating demand. While satellite Earth observation (EO) provides unprecedented...

Abstract Most ordinary earthquakes follow self-similar scaling, where source duration scales with the cube root of seismic moment. However, some earthquake clusters show non-self-similar scaling, in which source duration...

Aurora phenomenon is the most visible manifestation of space weather and play a crucial role in geoscientific studies of near-Earth space processes. Segmenting auroral image sequences from large vast observational data i...

To fully exploit the advantages of GNSS-R small satellites (large quantity, short revisit cycle) and address key challenges of multisource GNSS-R data&#x2014;track-wise distribution, uneven spatial coverage, and observat...

Abstract This study presents a geodetically derived seismicity-rate model for Kalimantan, Indonesia—a tectonically stable yet geologically diverse region with limited earthquake and fault data. Horizontal GNSS (Global ...

Long-term monitoring of coastal aquaculture ponds (APs) is essential for sustainable food production and environmental management. Intensive aquaculture has reshaped coastal landscapes and threatened ecosystem services. ...

Abstract Seafloor networks detect earthquakes and tsunamis more quickly than those on the mainland in the subduction zones. N-net was constructed in the western portion of the Nankai Trough subduction zone to fill the ga...

Low-Earth-orbit (LEO) satellites are regarded as a key enabler for 6G communications and localization, due to their large coverage beyond conventional terrestrial networks. In this paper, we propose a downlink LEO base s...

Artificial intelligence (AI) models developed for Global Navigation Satellite System Reflectometry (GNSS-R) observations have demonstrated competitive performance in estimating geophysical parameters, especially ocean su...

Flood disasters, with high suddenness, wide impact and severe consequences, severely threaten ecological security, human lives, property and socioeconomic development. Optical remote sensing, though advantageous in spati...

With increasing impacts of climate change, vulnerable low-lying developing countries like Bangladesh have coastal zones that experience disproportionate loss and damage (L&D) that exceed the limits of local adaptation. T...

Natural hazards such as earthquakes and combat scenarios create challenging conditions including uneven terrain and poor visibility, making rescue operations, medical supply delivery, and area assessment highly dangerous...

Indonesia is highly vulnerable to earthquakes that can trigger soil liquefaction, particularly in coastal regions where saturated sandy soils with low relative densities are prevalent. This study investigated the influen...

Abstract Glacier retreat transforms landscapes in polar and mountainous regions. Yet, the topography of the emerging terrain remains poorly known. Here, we present a physically consistent, global map of the ice-covered t...

Due to error sources arising from undersampling of target signals and imperfections in background models, the single-pair satellite gravity missions equipped with the low-low satellite-to-satellite tracking technology ar...

The NASA-ISRO Synthetic Aperture Radar (NISAR) mission will advance global soil moisture monitoring through high-resolution L-band observations. However, accurate fine-scale retrieval remains challenging due to the 12-da...
