Can I use WRF data with HYSPLIT?
The PC HYSPLIT menu interface provides a program (called “wrf2arl”) that converts NCEP WRF-NMM grib files to compatible HYSPLIT formatted meteorological files. To convert WRF-ARL NetCDF files, you will need to compile “arw2arl” found in the zip file of the /data2arl directory on a UNIX or MAC platform. We don’t provide a PC executable for WRF-ARW.
