Thread-topic: Produce a time serie by averaging a large variable

Hi ferreters,

How to calculate a time serie from a quite large 4D variable.

VMRN2O   N2O Volume Mixing Ratio          1:144     1:143     1:79      1:11315

Just a

yes? plot VMRN2O[i=@ave, j=@ave, k=@ave]
produce errors or killed process despite tries to increase the memory 
or setting 90% as the frugal mode rate.
No success.

What I do not understand is why the memory has to be so large
and finally why an internal chunk with only 144x143x79 cannot be made internally ?

Let me know if I have missed something.
Regards
Patrick
