HYSPLIT Automated Dispersion Model Simulations

READY logo


HYSPLIT has been configured to automatically produce atmospheric dispersion forecasts for several locations four times daily. These locations may change based on the needs of NOAA and its partners. The model assumes a unit of mass emission over 60 hours and produces graphics for two concentration grids: a fine grid (~ 1km horizontal resolution) and a coarse grid (~10 km horizontal resolution). Output on the fine grid extends from hour 1 to hour 12 each hour, while the coarse extends from hour 2 to hour 60 every 2 hours.
