The HYSPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectory) is a computer model that is used to understand how pollutants travel and spread in the air. HYSPLIT is one of the most extensively used models to simulate where something in the atmosphere is likely to go and to figure out where it came from. This model can be used to simulate the path of radioactive material, wildfire smoke, dust and volcanic ash among many other substances. It was recently used to simulate the transport of a
