[gradsusr] regrid data

[Robert Seigel]

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
