Description

The HYSPLIT dispersion module invokes the HYSPLIT_4 dispersion model to predict PM2.5 concentrations at ground level due to smoke from fires.  HYSPLIT is a complete system for computing simple trajectories to complex dispersion and deposition simulations using either puff or particle approaches.  Advection and diffusion calculations are made in a Lagrangian framework, while concentrations are calculated on a fixed Eulerian grid.
