As I understand, if I want to plot a precipitation map I need both RAINNC + RAINC parameters right?
And I guess it isn't enough: if I want to plot this map but just for 3 hr lets say at 06Z so I need to to this calculation:

Accumulated precipitation (at t=06Z) = (RAINNC(t=06Z)+RAINC(t=06Z)) - (RAINC(t=03Z)+RAINNC(t=03Z))

Is that correct?

If so - to do this for 1 hr difference - should I ran the model again? (because my files are every 3 hrs)

Hi Shai,
I believe the value is based on the history_interval, so if you would need to have that set to 60 (in minutes) to get the values for each hour.
