Free input data for initializing WRF at NCAR:

NCAR's Computational Information Systems Laboratory (CISL) is providing a number of datasets archived at NCAR for the latest year free and they can be otained online.

Free input data for initializing WRF at NOAA:

The NOAA National Operational Model Archive and Distribution System (NOMADS) provides near real-time and historical operational model data via web portal.

Real-time data from NCEP's ftp site:

NCEP provides a variety of regional (NAM) and global (GFS) data in GRIB format, and they can be used to initialize WRF in real-time. As of Feb 4 2008, all GFS and NAM data are in grib 2.

For NAM data, a popular dataset is the 40 km one, which has the following file names: nam.t{00,06,12,18}z.awip3dff.tm00.grib2, where ff stands for forecast hours. Forecast hours from 0 to 84 are available 4 times daily at 3 hourly interval.

For GFS data, a typical dataset is the 1 degree one, which has the following file names: gfs.t{00,06,12,18}.pgrbfhh.grib2 (where hh stands for forecast hour). Forecast hours from 0 to 384 are availably 4 times daily at 6 hour interval. For 0.5 degree data, try gfs.t{00,06,12,18}z.pgrb2fhh.
