FALL3D
FALL3D is a powerful 3D model designed to simulate the movement and deposition of volcanic ash, aerosols, and radioactive particles. It works using complex equations that tracks how these particles move, spread, and settle in the atmosphere. With the ability to run both in single and multiple computing environments, it offers flexibility for a wide range of simulations.
The model is versatile and can be used to recreate past volcanic events and provide real-time predictions. As a tool, it’s continuously being improved, with ongoing efforts to take advantage of the latest advancements in supercomputing. FALL3D is at the forefront of geophysical modeling, providing vital information for volcanic ash cloud forecasting.
Initially created to study volcanic ash dispersion, FALL3D is now used by academic and research institutions worldwide. Recent updates have expanded its capabilities, allowing it to handle a variety of atmospheric substances, including gases and dust. As part of the ChEESE project, FALL3D continues to lead innovation in atmospheric transport modeling.
This video shows a FALL3D-8.0 simulation of volcanic ash mass loading and has been initialised using data insertion of satellite retrievals. The simulation is for the 2011 Puyehue-Cordón Caulle eruption (see Prata et al., 2020, for details).
