PM2 .5 Chemical Composition and Geographic Origin of Air Masses in Mabopane, South Africa

X-Ray Spectrometry, Volume 55, Issue 3, Page 435-442, May/June 2026.
ABSTRACT Air pollution is a major global threat to health. The study aimed to analyze the chemical composition of PM2.5 in Mabopane, South Africa, and to identify the contribution of transported particulate pollution sources using backward air transport cluster analysis.

GOES‐R Series X‐Ray Sensor (XRS): 2. On‐Orbit Measurements and Calibrations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract An X‐Ray Sensor (XRS) has been onboard each of the National Oceanic and Atmospheric Administration (NOAA) Geostationary Operational Environmental Satellites (GOES) since 1975. XRS measures full‐disk soft X‐ray irradiance in two wavelength bands, 0.05–0.4 nm and 0.1–0.8 nm.

Advancing Systemic Risk Assessment for Complex, Interdependent Systems: A Research Agenda

Risk Analysis, Volume 46, Issue 5, May 2026.
ABSTRACT Engineering risk assessment has traditionally focused on direct impacts to individual assets or systems. However, as society's most notable risks increasingly stem from complex, interdependent systems, conventional methods fail to capture the cascading consequences and deepening uncertainty. Addressing this gap requires developing or extending

Ostwald Ripening in Underground Gas Storage

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Underground gas storage supports the energy transition, enabling long‐term CO2 ${\text{CO}}_{2}$ sequestration and seasonal H2 ${\mathrm{H}}_{2}$ storage. A key process shaping the fate of injected gases is Ostwald ripening—the curvature‐driven mass transfer between trapped ganglia—yet its behavior in confined porous structures remains poorly ...
