Hi,
<br />>
<br />> gfs.t12z.prgb2f12 is the 12 hour forecast started from
12Z. Clue is the f(forecast hour)
<br />>
<br />> gfs.t12z.prgb2f00 is the
3 minute or so forecast started from 12Z. Unfortunately the
<br />>
metadata doesn't mention it is a N minute forecast.
<br />>
<br />>
gfs.t12z.pgrb2anl is the analysis.
<br />>
<br />> The f00 is the model
state after a few time steps of the model integration. You

transients as the model adjusts from the analysis state to something
<br />>
on the "slow manifold".
