Data on the gravitational settling experiment and FLEXPART simulations output

AI summary Read the abstract

This is a dataset accompanying a research paper on long-range atmospheric transport of microplastic fibers, providing gravitational settling measurements and FLEXPART dispersion model simulation outputs. The data shows that fiber-shaped microplastics travel differently through the atmosphere than spherical particles, which matters for understanding how microplastics spread globally.

Data accompanying the research paper 'Shape matters: long-range transport of microplastic fibers in the atmosphere' by Tatsii et al., 2023 accepted by ACS Environmental Science and Technology journal. The uploaded text file refers to the experimental data on gravitationsl settling of microplastic fibers and spheres. Tar archives contain the FLEXPART (Lagrangian particle dispersion model) simulations output considering low and high scavenging efficiencies.

Gravitational settling of microplastic fibers: experimental results and implications for global transport

AI summary Read the abstract

This study measured the gravitational settling velocities of microplastic fibers and found that their non-spherical shape causes them to settle much more slowly than spheres of the same volume. Current atmospheric transport models that assume spherical particles significantly underestimate how long fibers remain airborne. These results have important implications for predicting how far microplastic fibers can travel before depositing.

The atmospheric settling of commercially sold microplastics

AI summary Read the abstract

Researchers measured the gravitational settling velocities of commercially available glitter microplastics (0.1-3 mm nominal diameter) and synthetic fibers (1.2-5 mm length) in air, finding that non-spherical shapes cause complex settling behaviors that deviate substantially from spherical particle models used in atmospheric transport models.

Atmospheric transport of microplastic particles as a function of their size and shape

AI summary Read the abstract

Researchers investigated the atmospheric transport and settling of microplastic particles as a function of size and shape, implementing a shape-correction parameterization for fiber-shaped particles in an atmospheric transport model to better represent their reduced gravitational settling velocity compared to spheres. The study showed that non-spherical fibers experience greater atmospheric drag, increasing their residence time and transport distance, and that including shape effects improved agreement between model output and ground-based measurements.
