[gradsusr] How to get the Sum of variable (not spatially) for all region

[Rowell, Mason D.]

Serge,

Find documentation on the asum (areal sum) function. It should accept the arguments you need.

Subject: [gradsusr] How to get the Sum of variable (not spatially) for all region

Dear all,

I have monthly data of one year. I used 'define new=sum(var,t=1,t=12)' then I obtain the sum of the spatial distribution for one year. This is more "in this point/coordinate, the annual precipitation is xxx mm"

But what I need is the total (sum) of the value of the variable. Something like: "In this area of 500km2, the annual precipitation is xxx mm".

Is it possible to obtain that?

Best regards
