Observation and Coordination Needs for Current, Near‐Future, and Next Generation Earth‐Observing SAR Systems

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract This paper summarizes an evaluation by experts of how coordination of Earth‐observing Synthetic Aperture Radar (SAR) missions among the world's space agencies could advance toward game‐changing scientific discoveries and fully realizing SAR's practical capability to address many issues facing society.

Detection of Equatorial Plasma Bubbles Using the COSMIC‐2 Rate of TEC Index

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Equatorial plasma bubbles (EPBs) are large‐scale plasma depletion structures that can disrupt Global Navigation Satellite Systems (GNSS) and other space‐based technologies. Several instruments have been employed to study EPB dynamics, with Total Electron Content (TEC) and Rate of TEC change Index (ROTI) data standing out as valuable parameters

A High‐Efficiency Multivariable TEC‐SOFTS Model for Ionospheric TEC Prediction: Validation Over China Area During Low and High Solar Activity Periods

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The ionospheric Total Electron Content (TEC) is a key parameter for characterizing the ionospheric properties. In this study, an efficient multivariable time series prediction model, TEC‐Series Core Fusion and efficient multivariable time series (TEC‐SOFTS), was constructed by combining multiple geomagnetic and solar activity indices ...

Snow Water Storage Within Eight Pacific Coastal Watersheds in British Columbia (Canada) Inferred From Four Years of Airborne Lidar Data

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Maritime mountain snowpacks are among the least understood and most poorly quantified components of global snow water storage, despite their vital role in sustaining water supplies and ecosystem health. Here, we present a 4‐year record of snow mass distribution across eight small‐to‐medium‐sized (5.2–63.4 km2) watersheds within the coastal ...

Scaling plant hydraulic traits to predict ecosystem fluxes under drought

New Phytologist, Volume 250, Issue 4, Page 2078-2084, May 2026.
Summary Expanding plant hydraulic trait measurements and advances in hydraulic modeling have improved mechanistic predictions of water–carbon fluxes under drought. However, mismatches between individual‐scale traits and ecosystem‐scale model representations introduce prediction uncertainties and obscure how drought impacts propagate across scales. This

Assessing functional diversity and composition using multispectral images in Atlantic Forest restoration sites

Restoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction By focusing on the specific functional traits of species, we can better understand how ecosystems function and respond to environmental change. However, field measurements of functional traits can be time‐consuming and costly, whereas remote sensing data can serve as viable alternatives for studying biodiversity at larger scales ...
