NWS Technical Procedures Bulletin 458, July 16, 1999

 

Abstract - The HYSPLIT model for the prediction of dispersion and deposition of radiological pollutant plumes was fully transferred to the NWS/NCEP Cray computer system on 26 October 1998 at 1200 UTC.  The HYSPLIT model has been used as the dispersion model component of NCEP / ARL's Regional Specialized Meteorological Center (RSMC) for transport model products since the RSMC's inception in 1992.  Prior to its transfer to NCEP, the model was run operationally on ARL's computer which is not the most suitable environment for use in an operational 7/24 program.
