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…

Major HYSPLIT Upgrade Scheduled June 12 June 2019 ARL’s HYSPLIT model will experience a number of behind-the-scenes upgrades when NOAA’s National Centers for Environmental Prediction (NCEP) implements a major upgrade to the agency’s Global Forecast System-Finite Volume Cubed (GFS-FV3) on June 12, 2019. The upgrades are not to the HYSPLIT model itself; rather, they’re changes…
