A Top‐Down View of Global and Regional Carbon Budgets From an Ensemble of Atmospheric Inversions

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Atmospheric inversions provide surface CO2 flux estimates based on in situ observed atmospheric CO2 mole fractions or satellite‐based column average CO2 (XCO2). Here, we provide a detailed assessment of 14 atmospheric CO2 inversions included in the Global Carbon Budget (GCB2024).

Eruption Source Parameters in Volcanic Plume Modeling: Advances, Challenges, and Future Directions

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Accurately predicting the atmospheric dispersion of volcanic ash and gases is crucial for both scientific understanding and hazard mitigation. Estimating Eruption Source Parameters (ESP), such as mass eruption rate, plume height, duration, and particle size distribution and properties, remains challenging due to the complex nature of volcanic ...

Linking Salinity and Precipitation Through Moisture Transport: A Study for the North Atlantic

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract Sea surface salinity (SSS) is a key indicator of the ocean–atmosphere freshwater balance and plays a central role in global moisture transport. This study investigates how extreme SSS anomalies in the North Atlantic (NATL) source region indicate atmospheric moisture pathways and precipitation in surrounding continental and island sink regions.

The Role of Moisture Transport Deficits in Modulating Drought and Fire Patterns in the Upper Paraguay River Basin, Brazil

Meteorological Applications, Volume 33, Issue 3, May/June 2026.
The Upper Paraguay River Basin faced intense droughts in 1999, 2007, and 2010, coinciding with extensive wildfires. In 2007, a severe drought episode affected 97.5% of its area. These extreme years were characterized by pronounced negative anomalies and shifts in atmospheric moisture contributions from key source regions, during dry season. ABSTRACT In

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).

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.

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 ...

Influence of biomass burning and anthropogenic emissions on ozone, carbon monoxide and black carbon at the Mt. Cimone GAW-WMO global station (Italy, 2165 m a.s.l.) [PDF]

Atmospheric Chemistry and Physics, 2013
This work investigates the variability of ozone (O₃), carbon monoxide (CO) and equivalent black carbon (BC) at the Italian Climate Observatory "O. Vittori" (ICO-OV), part of the Mt. Cimone global GAW-WMO station (Italy).

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).
