[gradsusr] Using Maskout Function To Compute Areal Average

[Perry, Aaron @ LSC]

I still can't seem to get this aave(maskout command to run properly.

I've attached my script and the associated MeteoInfo-generated ctl file to this email to see if anyone could take a look at it for me.

Perry,

you just open your data ctl file and then your maskout ctl file as 2.

for your area average: d aave(maskout(your_var,mask.2(t=1)),lon=X1,lon=X2,lat=Y1,lat=Y2)

mask.2 shows that variable mask is second file and use always (t=1) for mask as the t step is only.

Hope it solves your purpose!!!

Cheers,

Kishore

Look at GrADS online document: http://www.iges.org/grads/gadoc/gradfuncmaskout.html

You can open more than one data-descriptor file. Each file is numbered according to the order in which it was opened.

Good Evening All,

I'm currently trying to compute an areal average and I have created a masked out control file with MeteoInfo for the area that I'd like to compute an average of.

What do I do with the MeteoInfo-created .ctl file now?

The reason why I ask is because there's already a .ctl file for the displayed data and now there's one for just the area and I don't think that I want to be using them both at the same time...

Any guidance would be greatly appreciated.
