Technical note: The Lagrangian particle dispersion model FLEXPART version 6.2
TLDR
The Lagrangian particle dispersion model FLEXPART was originally designed for calculating the long-range and mesoscale dispersion of air pollutants from point sources, such as after an accident in a nuclear power plant.Abstract:
The Lagrangian particle dispersion model FLEXPART was originally (about 8 years ago) designed for calculating the long-range and mesoscale dispersion of air pollutants from point sources, such as after an accident in a nuclear power plant In the meantime FLEXPART has evolved into a comprehensive tool for atmospheric transport modeling and analysis Its application fields were extended from air pollution studies to other topics where atmospheric transport plays a role (eg, exchange between the stratosphere and troposphere, or the global water cycle) It has evolved into a true community model that is now being used by at least 25 groups from 14 different countries and is seeing both operational and research applications A user manual has been kept actual over the years and was distributed over an internet page along with the model's source code In this note we provide a citeable technical description of FLEXPART's latest version (62)read more

Characteristics of atmospheric transport into the Arctic troposphere
TL;DR: In this article, the Lagrangian particle dispersion model FLEXPART was used to construct a global data set of 1.4 million continuous trajectories and a climatology of transport in and to the Arctic was developed.

Cesium-137 deposition and contamination of Japanese soils due to the Fukushima nuclear accident
Teppei J. Yasunari,Andreas Stohl,Ryugo S. Hayano,John F. Burkhart,Sabine Eckhardt,Tetsuzo Yasunari +5 more
TL;DR: It is shown that 137Cs strongly contaminated the soils in large areas of eastern and northeastern Japan, whereas western Japan was sheltered by mountain ranges, which may help to coordinate decontamination efforts and plan regulatory measures in Japan.
Xenon-133 and caesium-137 releases into the atmosphere from the Fukushima Dai-ichi nuclear power plant: determination of the source term, atmospheric dispersion, and deposition
Andreas Stohl,Petra Seibert,Gerhard Wotawa,Delia Arnold,Delia Arnold,John F. Burkhart,Sabine Eckhardt,C. Tapia,Arturo Vargas,Teppei J. Yasunari +9 more
TL;DR: In this article, the authors determined the emissions into the atmosphere of two isotopes, the noble gas xenon-133 (133Xe) and the aerosol-bound caesium-137 (137Cs), which have very different release characteristics as well as behavior in the atmosphere.

TL;DR: In this article, the authors focus on one major aspect of cloud microphysics, which involves the processes that lead to the formation of individual cloud and precipitation particles, and provide an account of the major characteristics of atmospheric aerosol particles.

Flux-Profile Relationships in the Atmospheric Surface Layer
TL;DR: In this article, the free constants in several interpolation formulas can be adjusted to give excellent fits to the wind and temperature gradient data, and the behavior of the gradients under neutral conditions is unusual, however, and indicates that von Karman's constant is ∼0.35, rather than 0.40 as usually assumed, and that the ratio of eddy diffusivities for heat and momentum at neutrality is ∼1.0.

Parameterization of surface resistances to gaseous dry deposition in regional-scale numerical models
TL;DR: In this article, the authors proposed a method for estimating the dry deposition velocities of atmospheric gases in the U.S. and surrounding areas and incorporated it into a revised computer code module for use in numerical models of atmospheric transport and deposition of pollutants over regional scales.
