Setup Inline WRF/HYSPLIT Simulation
The HYSPLIT dispersion model has been configured to run within (inline) the WRF/ARW mesoscale meteorological model. Details on the Inline WRF/HYSPLIT model can be found at https://www.arl.noaa.gov/hysplit/inline-wrf-hysplit-coupling/. Currently, the the system is designed to create and run with 4 domains (6 hour spin-up) that are then available to run HYSPLIT offline, if needed:
For boundary conditions, WRF uses the AWRF archive (27 km) for 1980 to the end of the last year and the NARR data from the Research Data Archive at NCAR/UCAR (http://rda.ucar.edu) for the current year up to the end of the last month. Current forecasts can be produced for the last 9 days from the current day using the GFS forecast model for boundary conditions.
