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.

Concentrations, Solubility, and Deposition Fluxes of Aerosol Trace Elements in the Central Arctic During Winter and Spring: Results From the MOSAiC Expedition

Global Biogeochemical Cycles, Volume 39, Issue 10, October 2025.
Abstract Atmospheric deposition is an important pathway for delivering micronutrient and pollutant trace elements (TEs) to the surface ocean. In the central Arctic, much of this supply takes place onto sea ice during winter, before eventual delivery to the ocean during summertime melt.

Methane Sources in Cluj‐Napoca, Romania: Insights From Isotopic Analysis

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 18, 28 September 2025.
Abstract Increased emissions of methane (CH4 ${\text{CH}}_{4}$) have contributed 0.3–0.8°C to global temperature rise since preindustrial times. Reducing these emissions is crucial to mitigate climate change. Measurements of the isotopic composition of CH4 ${\text{CH}}_{4}$ (δ $\delta $13C and δ $\delta $2H) can be used to distinguish various sources ...

Going Off Grid: A Comparative Study of the Lagrangian and Eulerian Perspectives of New Particle Formation Events

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 18, 28 September 2025.
Abstract New particle formation and growth (NPF&G) is the process by which ultrafine particles are formed from gas‐phase precursors. NPF&G is the dominant source of global aerosol number with important influences on climate. Most observations of NPF&G events are conducted at stationary sites; however, NPF&G observed from stationary sites is influenced ...

Investigating the Large-Scale Transport of a Volcanic Plume and the Impact on a Secondary Site

Atmosphere, 2020
Volcanic plumes can be transported across vast distances and can have an impact on solar ultraviolet radiation (UVR) reaching the surface due to the scattering and absorption caused by aerosols.
