Assessing uncertainty in forecasts of refugia for Joshua trees using high‐density distribution data

open access: yesEcosphere, Volume 16, Issue 6, June 2025.
Abstract Joshua trees (Yucca brevifolia and Yucca jaegeriana) are iconic, foundational species of the Mojave and Sonoran Deserts in North America. Due to their ecosystem importance, long generation times, and low resilience to disturbance, these hybridizing sister species are increasingly the focus of conservation efforts.

Hydrological Effects of the Westward Expansion of Mediterranean Climate and Revegetation in Atlantic–Mediterranean Transitional Headwaters

open access: yesHydrological Processes, Volume 39, Issue 6, June 2025.
Six Spanish mid‐mountain catchments in a transitional Atlantic–Mediterranean ecotone reveal a westward expansion of Mediterranean climate: reduced spring precipitation in historically Atlantic catchments and increased autumn rainfall, coupled with rising temperatures and widespread greening.

High‐Electric Field Ultraviolet‐C Electroluminescence from LuPO4:Bi3+ Film on Silicon Substrate

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 6, June 2025.
A mercury‐free ultraviolet‐C (UVC) electroluminescent device is demonstrated using LuPO4:Bi3+ optical functional material on a silicon substrate. The device is connected to alternating polarities, and UVC emission is observed when the minimum electric field is reached through a process called impact ionization.

Coverage‐Limiting Factors Affecting the Monitoring of Urban Emissions With the Orbiting Carbon Observatory Missions

open access: yesAGU Advances, Volume 6, Issue 3, June 2025.
Abstract A growing number of space‐based platforms, like the Orbiting Carbon Observatory (OCO‐2 and OCO‐3) missions, observe Earth's atmospheric carbon dioxide CO2 $\left(\mathrm{C}{\mathrm{O}}_{\mathrm{2}}\right)$ concentrations with high accuracy and precision.

Assessing Clouds in GFDL's AM4.0 With Different Microphysical Parameterizations Using the Satellite Simulator Package COSP

open access: yesEarth and Space Science, Volume 12, Issue 6, June 2025.
Abstract We evaluate cloud simulations using satellite simulators against multiple observational data sets. These simulators have been run within the Geophysical Fluid Dynamics Laboratory's Atmosphere Model version 4.0 (AM4.0), as well as an alternative configuration where a fully two‐moment Morrison‐Gettelman cloud microphysical parameterization with ...

A Novel Algorithm for Ice‐Water Discrimination in Large Lakes Using ICESat‐2 Altimetry and Data Driven Machine Learning

open access: yesEarth and Space Science, Volume 12, Issue 6, June 2025.
Abstract Large freshwater lakes are critical for human life, ecosystem functioning, and the global carbon cycle. However, consistent high‐resolution methods to characterize ice over large lakes remain limited. Here we develop an algorithm to progress ice observations over inland bodies of water by improving surface classifications using data derived ...

Hypereutrophication, Hydrogen Sulfide, and Environmental Injustices: Mechanisms and Knowledge Gaps at the Salton Sea

open access: yesGeoHealth, Volume 9, Issue 6, June 2025.
Abstract The Salton Sea, California's largest lake, is undergoing significant environmental degradation, which has adverse health effects on nearby rural communities, primarily Latinx and Torres Martinez Desert Cahuilla Indian. Over the past two decades, the lake's water levels have steadily dropped.

Effusion Rate Trends at Piton de la Fournaise: A Review of 24 Years of Space‐Based Thermal Observation

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract We combined thermal satellite imagery from Moderate Resolution Imaging Spectroradiometer (MODIS) and Visible Infrared Imaging Radiometer Suite (VIIRS) instruments to reconstruct the effusion rate trends in terms of Time Averaged Discharge Rate (TADR) of 37 eruptions (2000–2023) at Piton de la Fournaise (La Réunion, France).
