Meltwater as a Local Source of Ice Nucleating Particles in the Central Arctic Summer

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Identifying sources of ice nucleating particles (INPs) in the central Arctic is important for understanding controls on the phase of Arctic mixed‐phase clouds (AMPCs). We show meltwater samples collected from the Arctic pack ice in July 2020 contain biological INPs active at relatively warm temperatures (T ≥ −10°C).

Long‐Range Transport Pathways of Intense Wildfire Plumes in the Northern Hemisphere Observed by the IASI/METOP Satellite Mission

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Wildfires emit significant greenhouse gases and pollutants. Extreme fires disperse smoke plumes over long distances, necessitating a deeper understanding of their source regions and variability. This study introduces a plume back‐trajectory algorithm using carbon monoxide (CO) and peroxyacetyl nitrate satellite observations from the Infrared ...

DMS Uplift by Tropical Cyclones as a Source of SO2 in the Upper Troposphere

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Airborne observations from ACCLIP on 2 August 2022, combined with Lagrangian particle dispersion model back trajectories, reveal that SO2 mixing ratios at 14–16 km were enhanced by a factor of 4–6 in regions influenced by tropical cyclones (TCs).

Strong Ventilation Drives the Aerosol Pollution Receptor Center and Its Interannual Variability in Central China's Twain‐Hu Basin

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract This study investigates the unique winter phenomenon in central China's Twain‐Hu Basin where high aerosol optical depth (AOD) centers coincide with a regional near‐surface wind speed maximum. Based on multi‐decadal reanalysis data sets, satellite retrievals, ground observations, and FLEXPART‐WRF simulations, we demonstrate that strong ...

A Graph Signal Processing Approach to the Characterization of Xe‐133 Atmospheric Background

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The geopolitical context advocates for monitoring nuclear activities within an international framework. In this context, the Comprehensive Nuclear‐Test‐Ban Treaty Organization has established measurement stations, known as the International Measurement System (IMS).

Spatiotemporal variation of radionuclide dispersion from nuclear power plant accidents using FLEXPART mini-ensemble modeling

, 2023
We investigate the spatiotemporal distribution of the radionuclides including iodine-131 (131I) and cesium-137 (137Cs), transported to Qatar from fictitious accidents at the upwind Barakah nuclear power plant (B-NPP) in the United Arab Emirates (UAE). To

Impacts of Low‐Level Jets on Moisture Transport to the Pantanal, Brazil

International Journal of Climatology, Volume 46, Issue 3, 15 March 2026.
The moisture transports from the tropics to the subtropics by the low‐level jets (LLJs) east of the Andes crossing the Pantanal region. Four LLJs, east of the Andes, were identified and selected with correspondent Lagrangian moisture transport. The LLJ moisture source regions contribute to Pantanal (~63.5%) and precipitation increased (~30%) during LLJ

The Identification of Iran’s Moisture Sources Using a Lagrangian Particle Dispersion Model

Atmosphere, 2018
Iran has faced many water shortage crises in the past. Iran’s moisture sources for precipitation were identified by Lagrangian approach using the FLEXible PARTicle dispersion model (FLEXPART) v9.0 model.
