HYSPLIT

HYSPLIT (HYbrid Single-Particle Lagrangian Integrated Trajectory) is a computational model used to predict how air pollutants, wildfire smoke, or other airborne particles move and spread in the atmosphere. It uses data on wind patterns, temperature, and weather to simulate the path of particles over time. This helps scientists and public health officials understand where pollutants might travel, assess environmental impacts, and make informed decisions about air quality and safety. Essentially, HYSPLIT acts like a virtual weather map for tracking the journey of particles through the air.
