[gradsusr] Average of a parameter

[Andrew Friedman]

Hi Thareh,
As written, your script averages over space, not time.
If you are trying to average over time, you should use an average of the form
‘ave(prate,t=517,t=643)'
Also, if you’re trying to calculate a spatial average, I suggest using ‘aave’.
