2026-06-03 Asteroid impact cratering and ejecta dust diffusion process doi:10.57760/sciencedb.space.03621 en Quantitative analyses are performed on the dynamic cratering process induced by asteroid impacts as well as the mass and dynamic characteristics of ejecta dust. The FLEXPART (Flexible Particle Dispersion Model) is adopted to quantify the temporal effects and global spatial distribution of stratospheric dust dispersion. impact cratering; ejecta dust; disaster effects liu qin qin Shen Xuhui PUBLIC https://creativecommons.org/licenses/by-nc/4.0/ dataset http://www.doi.org/10.1360/csb-2025-5313 Science Data Bank
