[gradsusr] Areal Average over Depth

[Joseph Basconcillo]

Good day! I want to create a timeseries data of subsurface ocean temperature from 100-300m using global domain. I suppose the function aave can produce timeseries in one depth level. Using global domain does not make sense but I want to test it first then proceed to regional domain. 

Say, if I do.. 

set x 1 
set y 1 
set z 10 20 
set t 1 last 
d tloop(aave(var, global)) 

Error says the Z cannot vary. So I want to take the average value of Z from 10th-20th depth level. Is there a way to do this in GrADS? I looked at the function vint. How can I used that in my problem? Thank you. 

Yours, 
Joseph Basconcillo
