Local Variability of Ice Core Ammonium and Black Carbon Records From Tunu and Summit, Greenland: Implications for Long‐Term Biomass Burning Reconstructions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Paleoclimate reconstructions of wildfire using ice cores often rely on high‐resolution aerosol records of refractory black carbon (rBC) or ammonium (NH4+). The interpretation of such records, however, can be hindered by uncertainties related to long‐range atmospheric transport, spatial distribution and strength of emissions, as well as ...

FLEXINVERT: an atmospheric Bayesian inversion framework for determining surface fluxes of trace species using an optimized grid [PDF]

Geoscientific Model Development, 2014
We present a new modular Bayesian inversion framework, called FLEXINVERT, for estimating the surface fluxes of atmospheric trace species. FLEXINVERT can be applied to determine the spatio-temporal flux distribution of any species for which the ...

Ensemble‐Based Analysis and Moisture Sources of Double Rainbands Over South China

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract This study investigates the role of moisture in double rainbands over South China through combining ensemble sensitivity analysis and Lagrangian backward tracing. During 10–11 May 2022, a high‐impact double‐rainband event hit South China with coexisting inland and coastal heavy rainfall.

Flex_extract v7.1 – A software to retrieve and prepare ECMWF data for use in FLEXPART [PDF]

, 2020
Abstract. Flex_extract is an open-source software package to efficiently retrieve and prepare meteorological data from the European Centre for Medium-Range Weather Forecasts (ECMWF) as input for the widely-used Lagrangian particle dispersion model FLEXPART and the related trajectory model FLEXTRA. ECMWF provides a variety of data sets which differ in a

Characterizing aerosol sources based on aerosol optical properties and dispersion modelling in a Scandinavian Coastal Area (Aarhus, Denmark) [PDF]

Aerosol Research
Coastal aerosols are formed through the complex mixing between marine air masses and continental emissions, which originate from both natural and anthropogenic sources.

Anthropogenic Pollution Accounts for a Substantial Part of Cloud Condensation Nuclei in North African Dust Layer

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Cloud condensation nuclei (CCN) modulate the properties and thus the climate effects of clouds. The North African dust plume is an important source of CCN in the North Atlantic trade‐wind zone. Yet, research into the nature and sources of these CCN is sparse, making it difficult to fully assess related cloud effects. Using combined airborne in

Relation between PM_2.5 and O₃ over Different Urban Environmental Regimes in India

Urban Science, 2023
Atmospheric ozone (O3) concentration is impacted by a number of factors, such as the amount of solar radiation, the composition of nitrogen oxides (NOx) and hydrocarbons, the transport of pollutants and the amount of particulate matter in the atmosphere.

Atmospheric Dust Transport to High‐Elevation Dronning Maud Land, Antarctica, Modulated by Cyclonic Circulation, the Pacific Decadal Oscillation, and Source Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract The dependence of aeolian dust transport on atmospheric circulation patterns allows dust preserved in Antarctic ice cores to serve as a proxy for past circulation variability. Here, we investigate dust transport to high‐elevation Dronning Maud Land (DML) in Antarctica through analysis of the 1300‐year‐old ISOL‐ICE ice core dust record together

Enhanced Moisture Uptake Fuels North Atlantic Tropical Easterly Waves Precipitation in a Downscaled CMIP6 Projection

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Tropical easterly waves (TEWs) are critical drivers of the tropical North Atlantic hydroclimate, yet their future behavior remains uncertain. Using a high‐resolution, dynamically downscaled, bias‐corrected CMIP6 data set and a Lagrangian moisture tracking approach, we provide the first comprehensive, basin‐wide projections of future changes in

Contrasting Trends in Atmospheric Net Moisture Flux and Its Linkage to Source and Sink Regions Across the Yellow River Basin Over Four Decades

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract Atmospheric moisture transport and precipitation recycling processes are key to understanding regional water cycle under climate change. Using the two‐layer Water Accounting Model (WAM‐2layers) with ERA5 reanalysis data, we analyzed the atmospheric net moisture flux across the Yellow River Basin from 1980 to 2023.
