Comparison of Soil Mineralogy From EMIT Imaging Spectroscopy and Ground‐Based Measurements in the Deserts of Southern California

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract The highly variable spatial composition of desert soils remains a major source of uncertainty in estimates of dust radiative forcing. Existing soil mineralogy data sets used in climate models are limited by sparse ground observations and coarse spatial resolution.

Revealing the Formation of the <20 MeV Inner Proton Radiation Belt at L ∼ 2 During the 10–11 May 2024 Superstorm

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract A new proton radiation belt was identified during the geomagnetic superstorm of 10–11 May 2024. To investigate its origin, we use an MHD‐test particle simulation to model solar energetic proton (SEP) trapping and the evolution of the initial trapped proton population during the storm.

Experimental Study on Cooling Uniformity and Hotspot Suppression Characteristics of Air‐Cooled PEMFC With Fan Configuration

open access: yesFuel Cells, Volume 26, Issue 3, June 2026.
ABSTRACT Air‐cooled polymer electrolyte membrane fuel cells (PEMFCs) offer structural simplicity and advantages in compact system design; however, nonuniform thermal management induced by fan‐based cooling can lead to hotspot formation, resulting in increased membrane resistance, performance degradation, and reduced durability.

Drive Cycle‐Based Accelerated Stress Tests for Heavy Duty Fuel Cell Vehicle Applications

open access: yesFuel Cells, Volume 26, Issue 3, June 2026.
ABSTRACT Fuel cells in heavy‐duty vehicles are susceptible to degradation and are significantly influenced by driving patterns. Accelerated stress tests (ASTs) are useful to identify these degradation mechanisms and aid the development of degradation‐resistant control strategies for FC stacks.

Pediatric Risk Mapping From Co‐Exposure to Extreme Temperatures and Air Pollutants

open access: yesGeoHealth, Volume 10, Issue 6, June 2026.
Abstract Exposure to extreme temperatures and fine particulate matter is hazardous to human health, especially among children. With growing evidence on the impact of these environmental hazards on child health—including increased risks of respiratory illnesses, heat‐related illnesses, and developmental challenges—there is a substantial need to identify
