[Wrf-users] Help with GFS data to force WRF

[Jose Augusto Paixão Veiga]

Hi Barry,

To access GFS data I do the following steps:

1) go to the WRF user site (http://www2.mmm.ucar.edu/wrf/users/)

2) I access the link Download (Input Data from NCAR)

3) I choose the link to access  NCEP Final Analysis (GFS-FNL) *ds083.2 *

4) Go to https://rda.ucar.edu/datasets/ds083.2/#!access

5) And final
l
y I access the products *GRIB2 6 HOURLY FILES 2007.12.06* to current (get
converted files)
.

Is this wrong?
