[gradsusr] Max Function

[Walsh, Brian J]

Hello Grads Users,

I'm trying to calculate the maximum 3-hourly precipitation amounts from one model in a given domain.

So, for instance, if I choose a point (say 46.0 N 57.0W), I would like to get the maximum 3-hourly precipitation amounts from the GFS for the surrounding grid points (i.e. I don't want a point forecast prediction).  I'm not sure if I can have it output the maximum amount from the nearest neighbor grid points or if I need to specify a domain.

I've tried the max function without success and was hoping someone may have done something similar and it worked.  I'm looking to output the data into a file, not plot it.

Any help would be greatly appreciated.

Thanks

Brian
