[gradsusr] regrid data

[Yan Libin]

Rob,

You can download OpenGrADS from this link
http://sourceforge.net/projects/opengrads/files/grads2/2.0.1.oga.1/Linux/ 
I guess this bundle has regrid function (re2) after you install it.
It is not a script under windows platform, so maybe the same under linux platform.
After installation, you can do like this:

define var1=re2(var,1,1)
d var1

You can have a try.
Good luck.

Libin

I am using a Linux platform with grads-2.0.a9. Is there a linux script?

If you are working on a windows platform,  you can download OpenGrADS which has the regrid function already.

Thank you for the quick response, Yan. 


When I type that, I get the following response from grads: 


Syntax Error:  Invalid Operand 
  're2' not a variable or function name
  Error ocurred at column 1
DEFINE error:  Invalid expression. 


Do you have a copy of the re2() script? 


Thanks,
Rob

Hi,

I am trying to regrid NAM data to match up with GFS resolution. I have seen numerous posts regarding regrid2() or re(), however I cannot seem to find any of these scripts. I have downloaded a bundle and found regrid2(), but could not get it to work. It gave me errors similar to previous posts ('regrid2' not a variable or function name). Does anyone have (or know where to find) a script that regrids data to a more coarse resolution? 

Thanks,
Rob
