A study on atmospheric relative dispersion using the transport model FLEXPART
, 2011 Relative dispersion is a widely used measure to characterize mixing properties of atmospheric passive tracers. Numerical models allow for a large number of particles. In this thesis, the Lagrangian transport model FLEXPART has been used to generate particle trajectories.

Digital Twin Development in Omniverse: the FLEXPART Particle Dispersion Case
The first use of a digital twin goes back to the 1960's, originating from NASA, when they attempted to create one for the Apollo 13 mission using multiple simulators, with the intent of failure prediction and error prevention. Although the concept of digital twins has been around for several decades, the recent boom in the fields of computer ...

Review comments for "The Lagrangian particle dispersion model FLEXPART version 10.3"
, 2019 openaire +1 more source
Journal of Geophysical Research D: Atmospheres, 2023 Abstract This paper makes use of a combination of FLEXPART‐WRF simulations forced with ERA5 and the CESM2 model—incorporated in the CMIP6 project—to infer a series of changes over the present century in the behavior of the landfalling atmospheric rivers (ARs) arriving to the Iberian Peninsula.

Lagrangian Particle Dispersion Models in the Grey Zone of Turbulence: Adaptations to FLEXPART-COSMO for Simulations at 1 km Grid Resolution [PDF]
Boundary-Layer Meteorology, 2022 Lagrangian particle dispersion models (LPDMs) are frequently used for regional-scale inversions of greenhouse gas emissions. However, the turbulence parameterizations used in these models were developed for coarse resolution grids, hence, when moving to ...

Effects of improved interpolation in the wet-scavenging scheme of FLEXPART
2021<p>The Lagrangian dispersion model FLEXPART v10.4 uses cloud water content, temperature, and precipitation rates to calculate wet scavenging. Currently, only precipitation fields are interpolated spatially to the particle positions. A simple nearest-neighbour approach is used for cloud parameters and temperature. This is made worse by the

Scavenging and Convective Clouds in the Lagrangian Dispersion Model FLEXPART
2017The Lagrangian particle dispersion model (LPDM) FLEXPART includes a parameterisation of wet scavenging. With FLEXPART version 8, an improved scheme was introduced which distinguishes between in-cloud and below-cloud scavenging. However, clouds are only diagnosed from grid-scale variables and thus convective clouds are neglected. Although the convection
