Seeking the origins of Arctic ice nucleating particles with FLEXPART-WRF
2023The Arctic region is subject to polar amplification, causing it to warm approximately four times faster than the global average. The predominance of ice and mixed-phase clouds in high latitude regions causes strong uncertainties in the determination of the cloud radiative effect and the cloud feedback.

Forecasting long-range atmospheric transport episodes of polychlorinated biphenyls using FLEXPART [PDF]
Atmospheric Environment, 2013 The analysis of concentrations of persistent organic pollutants (POPs) in ambient air is costly and can only be done for a limited number of samples. It is thus beneficial to maximize the information content of the samples analyzed via a targeted observation strategy.

FLEXPART model sensitivity study for the footprint of a Swiss tall tower site
2022<p>Flux towers are essential tools for collecting measurements of trace gas concentrations/fluxes to investigate source regions of greenhouse gases (GHGs) and other pollutants. Most flux towers provide observations at heights of several meters to tens of meters and therefore only sample potential source regions in their immediate vicinity,

Simulation of mineral dust transport to the East China Sea with FLEXPART 10.4
2020<p>Particulate matter is of special interest in atmospheric studies because it has important effects on both the Earth's climate and on human health.&#160; Currently, aerosols contribute largest to the overall uncertainty of the net radiative effects in studies of climate change.&#160; At the same time, aerosols ...

An Integrated clear air turbulence scheme for the FLEXPART model
Atmospheric turbulence above the planetary boundary layer (PBL) plays a critical role in the vertical and horizontal mixing of aerosols and trace gases. In the troposphere, such turbulence is highly intermittent and primarily associated with jet stream boundaries and planetary-scale waves, while in the stratosphere it is strongly modulated by the quasi-Lokahith Narendra Agasthya +1 more

Tracking the sources of atmospheric microplastic using FLEXPART v.
An emerging number of studies highlighted the presence of microplastic in the atmosphere all over the world. The presence of such particles has been observed at the poles, in the marine atmosphere above the surface of the oceans, in clouds, on the fresh snow of high mountains and high concentrations has been observed in the atmospheric fallout in ...Silvia Bucci +4 more

Offline-Coupling of the Lagrangian Particle Dispersion Model FLEXPART to ICON
Over the last years, the numerical weather prediction (NWP) and climate model ICON has become the operational forecasting tool for several national weather services and research groups. Operational analysis or re-analysis fields from NWP models are often used as input for offline-coupled atmospheric chemistry and transport models.Stephan Henne +3 more

Energy and heat transport in the atmosphere using the Lagrangian model FLEXPART
Natürliche Klimaschwankungen beeinflussen die atmosphärischen Zirkulationen unseres Klimasystems, welche das Wetter in Regionen weltweit beeinflusst. Die wichtigste Klimavariabilität ist die El Niño Southern Oscillation (ENSO), die weltweit Extremereignisse, z.B. Dürren, beeinflusst.openaire +1 more source
