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…
Credit: NOAA NOAA Modeling Fair to Feature Two ARL Research Areas September 2018 NOAA’s first General Modeling Meeting and Fair will take place September 10-12, 2018 at its Center for Weather and Climate Prediction in College Park, Maryland. Organized under the theme “Interdisciplinary Modeling and Partnerships,” this event is an opportunity for the NOAA modeling…
ARL’s HYSPLIT Model Sets New Usage Record in 2017 January 2018 ARL’s HYSPLIT model is well-known in the atmospheric science community as one of the most widely used models for atmospheric trajectory and dispersion calculations. Publicly available via ARL’s Real-time Environmental Applications and Display sYstem (READY) web server (https://www.ready.noaa.gov), users worldwide are able to access…

Laboratory Science Review June 21-23, 2016 Research Areas Atmospheric Dispersion and Boundary Layer Characterization The accidental or intentional release of chemical, biological, or nuclear agents, as well as ash associated with volcanic eruptions, can have significant health, safety, national security, economic, and ecological implications. The Air Resources Laboratory (ARL) provides critical modeling and observation data…
HYSPLIT Model Update to be Released to the Public A major update to the HYbrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model will be released to the public, as a downloadable version, through the Air Resources Laboratory’s web site on February 24th. Many of the changes made by ARL since the last update (February 2008) are…
Research Highlight: ARL to Train Argentina’s National Weather Service on HYSPLIT model Beginning September 29 through October 2, the Air Resources Laboratory (ARL) will train staff at Argentina’s National Weather Service (NWS) on the HYbrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) transport and dispersion model to help them support operations at their Volcanic Ash Advisory Center…
Research Highlight: ARL Delivers Improved HySPLIT capabilities to NWS The Air Resources Laboratory (ARL) delivered model enhancements to the National Weather Service’s National Centers for Environmental Prediction (NCEP) for their operational Hybrid Single-Particle Lagrangian Integrated Trajectory (HySPLIT) transport and dispersion model. These enhancements allow for long-range dispersion beyond 4 days and for back-tracking capabilities and…
