Long‐Wavelength Ionospheric Compensation of InSAR Time‐Series Based on Global Ionosphere Maps

Geophysical Research Letters
Uncorrected long‐wavelength contributions remain a major limitation for interpreting InSAR time‐series over large areas (>100 km). Among them, the ionosphere can impact InSAR measurements across various timescales, potentially biasing secular velocity ...

Fusion of GNSS and Satellite Radar Interferometry: Determination of 3D Fine-Scale Map of Present-Day Surface Displacements in Italy as Expressions of Geodynamic Processes

Remote Sensing, 2019
We present a detailed map of ground movement in Italy derived from the combination of the Global Navigation Satellite System (GNSS) and Satellite Synthetic Aperture Radar (SAR) interferometry.

Legacy effects of locally extinct flagship species on protected areas

Frontiers in Ecology and the Environment, EarlyView.
Protected areas (PAs) are often established to conserve flagship megafauna so as to mobilize political support and secure sustained conservation investment, with the expectation that flagship‐centered governance will also protect habitat. Despite such efforts, flagship species can experience extirpation, raising a fundamental question: do conservation ...

Warm‐wet transition restructures arid lake microbiomes and functional potential

iMetaOmics, EarlyView.
This study summarizes how a long‐term warm‐dry to warm‐wet transition restructures microbiomes and functional potential in Lake Bosten, an arid lake in northwestern China. Warm‐wet hydroclimatic change increased water level and hydrological connectivity, while decreasing salinity and total nitrogen.

Assessment of the Performance of SWOT for Observing the Static Ocean Topography

Geophysical Research Letters
Marine geodetic references, such as the mean sea surface (MSS), are currently limited by the spatial resolution of conventional satellite altimeters. We analyze the new swath‐altimetry data from the Surface Water and Ocean Topography (SWOT) satellite, to

Infant frontal alpha asymmetry predicts social attention and transdiagnostic risk for emotional reactivity

JCPP Advances, EarlyView.
Abstract Background Differences in Frontal Alpha Asymmetry (FAA), derived from the electroencephalogram (EEG), have been associated with approach‐withdrawal behavior, although inconsistently. The current study examined how early patterns of FAA during the first 2 years of life relate to various socioemotional characteristics (at 2 years) and ultimately

Intercomparison of a Regional Climate Model Ensemble for Selected European Catchments

International Journal of Climatology, EarlyView.
This study analyzes a regional climate model ensemble for water cycle and water resource research with two models. Results show that ICON generally outperforms TSMP1 simulations, mainly with 2‐m temperature and precipitation. These findings serve as a baseline evaluation that shows how key structural differences influence the model skill.

Detecting Transient Uplift at the Active Volcano Ol Doinyo Lengai in Tanzania With the TZVOLCANO Network

Geophysical Research Letters
Over the last 7 years, geodetic data have detected periods of uplift and subsidence of the active volcano Ol Doinyo Lengai in Tanzania. Although numerous eruptions of the volcano have occurred historically, a systematic investigation of transient ...

Recent unrest (2002–2015) imaged by space geodesy at the highest risk Chilean volcanoes: Villarrica, Llaima, and Calbuco (Southern Andes)

, 2017
Villarrica, Llaima, and Calbuco volcanoes are the most active and dangerous volcanoes in the Southern Andes, and we use Interferometric Synthetic Aperture Radar (InSAR) observations from multiple satellites (ERS-2, ENVISAT, ALOS, RADARSAT-2, COSMO-SkyMed,
