[gradsusr] GFS hourly clouds output

[James T. Potemra]

Hi Ivan,

Are you getting these from a single forecast run?  If not, and you are 
looking at an aggregation of different forecasts, you might be seeing an 
impact from re-initialization of the model (I think the GFS is run at 
00, 06, 12 and 18 daily).
