Smoke Dispersion from Forest Fire Combustion Products—Implementation at Strategic, Tactical and Operational Level

Environmental Sciences Proceedings, 2023
An increase in the frequency of wildfire occurrence is predicted in all climate model estimates, implying significant health impacts, due to the emission of combustion products.

Dominant transport pathways in an atmospheric blocking event [PDF]

, 2015
A Lagrangian flow network is constructed for the atmospheric blocking of eastern Europe and western Russia in summer 2010. We compute the most probable paths followed by fluid particles which reveal the {\it Omega}-block skeleton of the event.

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.

Unraveling the discrepancies between Eulerian and Lagrangian moisture tracking models in monsoon- and westerly-dominated basins of the Tibetan Plateau [PDF]

Atmospheric Chemistry and Physics
Eulerian and Lagrangian numerical moisture tracking models, which are primarily used to quantify moisture contributions from global sources to specific regions, play a crucial role in hydrology and (paleo)climatology studies on the Tibetan Plateau (TP ...

Impact of transport model resolution and a priori assumptions on inverse modeling of Swiss F-gas emissions [PDF]

Atmospheric Chemistry and Physics, 2023
Inverse modeling is a widely used top-down method to infer greenhouse gas (GHG) emissions and their spatial distribution based on atmospheric observations.

Sources and Secondary Production of Organic Aerosols in the Northeastern United States during WINTER [PDF]

, 2018
Most intensive field studies investigating aerosols have been conducted in summer, and thus, wintertime aerosol sources and chemistry are comparatively poorly understood.

The Lagrangian particle dispersion model FLEXPART version 10.4 [PDF]

, 2020
<p>Following its release and corresponding publication in GMD, we present the Lagrangian model FLEXPART 10.4, which simulates the transport, diffusion, dry and wet deposition, radioactive decay and first order chemical reactions of atmospheric tracers.

Contribution of water-limited ecoregions to their own supply of rainfall [PDF]

, 2016
The occurrence of wet and dry growing seasons in water-limited regions remains poorly understood, partly due to the complex role that these regions play in the genesis of their own rainfall.
