FALL3D FALL3D is a 3D model for atmospheric passive transport and deposition of particles, aerosols, and radionuclides based on the so-called advection-diffusion-sedimentation (ADS) equation. The model was originally developed for inert volcanic particles (tephra) and has a track record of 50+ publications on different model applications and code validation, as well as an ever-growing community of users worldwide, including academia, private, research, and several institutions tasked with operational forecast of volcanic ash clouds. The code version 8.x has been redesigned and rewritten from scratch in order to overcome legacy issues and allow for successive optimisations in the preparation towards extreme-scale computing. The new versions include significant improvements from the point of view of model physics, numerical algorithmic methods, and computational efficiency. In addition, the capabilities of the model have been extended by incorporating new features such as the possibility of running ensemble forecasts and dealing with multiple atmospheric species (i.e. volcanic ash and gases, mineral dust, and radionuclides). Ensemble run capabilities are supported since version 8.1, making it possible to quantify model uncertainties and improve forecast quality. The FALL3D code is one of the flagship codes included in the European Centre of Excellence for Exascale in Solid Earth (ChEESE).
