Atmospheric Transport and Dispersion

ARL scientists perform activities to understand the main processes that drive the transport and dispersion of harmful substances in the atmosphere, to improve the quality of our modeling tools, and to assess the uncertainties and applicability of those tools. In addition, investigations of the transport and dispersion of chemicals in the atmospheric boundary layer serve…

Atmospheric Transport: HYSPLIT & READY

Transport-Dispersion Modeling Developed and maintained by ARL, HYSPLIT is the core engine of ARL’s transport-dispersion modeling activities and it is one of the most widely used models for atmospheric trajectory and dispersion calculations in the US and internationally. HYSPLIT is a complete system for computing simple air parcel trajectories as well as complex transport, dispersion,…

About

About ARL NOAA’s Air Resources Laboratory (ARL) conducts research on the lowest part of the atmosphere, the boundary layer, the area where we live and breathe. World-class research on the chemistry and physics of the boundary layer contributes to accurate regional and global predictions of weather and air quality, as well as climate variability. ARL…

HYSPLIT

HYSPLIT HYSPLIT models simulate the dispersion and trajectory of substances transported and dispersed through our atmosphere, over local to global scales. HYSPLIT is a complete system for computing simple air parcel trajectories, as well as complex transport, dispersion, chemical transformation, and deposition simulations. HYSPLIT continues to be one of the most extensively used atmospheric transport and…
