[gradsusr] GFS data

[Gisele dos Santos Zepka]

Hello users,

I need to run WRF for 24 hours using 0.5 deg GFS data (analysis from 12 
UT + 24 forecasts). So, my first GFS file is gfs.t12z.pgrb2f00 (that I 
believe to be the analysis), and every 3 hours I have the GFS forecasts 
being the last file gfs.t12z.pgrb2f24. I don't know if they are the 
right files to use. I am also confused between two archives 
gfs.t12z.pgrb2f00 and gfs.12z.pgrb2f12, which of them is the analysis?

Any help will be welcome.

Thanks.
