[Wrf-users] GFS Variable for WRF

[hamza altınsoy]

Dear Wrf users,

I am a new user.( I started to  use wrf since last month)
Until this week, I can solve my problems by reading your answers from
internet. Thank you very much for this.
However, I faced some problems, and it can  take very long time if I try to
solve them or may be I can't solve them. Could you please help me?
My problems are

1- From
http://motherlode.ucar.edu:8080/thredds/ncss/grid/fmrc/NCEP/GFS/Global_onedeg/forecast/NCEP-GFS-Global_onedeg_ConstantForecast_2010-11-27T03:00:00Z/pointDataset.htmlweb-site
I want to download appropriate data set for WRF. I think , I have
to use Vtable.GFS but I don't know which data set I have to download. Could
someone say which ones are appropriate. I am sending the lists of variables
as attachment

2- These data sets are netcdf files. Have to I convert it to grib format.If
yes, is there a simple way to do this

3- Instead of real case simulation, I am also dealing with ideal case part
of WRF. Could you say which ideal case is convenient to forecast
precipitation, temperature and wind velocity. Is there a document which
describes ideal cases?

Tahnk you very much
Best Wishes
