[gradsusr] GFS time interpolation

try attacched script
open a file with 1h grid
set time to something in 1h grid
open your 3h grid
set dfile 3h grid
run the script: the only parameter is the field of 3h grid you want to interpolate (ex.: interp_time mslp)
now defined variable 'interp' is an interpolation of 3h grid into 1h grid

it should work
bye bye

Any idea on how to achieve this? Maybe using some CDO operators?
Any help would be apreciated.

I want to interpolate 3h GFS grib files to 1h grib files in order to get hourly animations.
Does anyone know how to do it?

One option is writting a GrADS script to get the intermediate values by manually interpolation, but I'm wondering if is there any way to get directly an hourly interpolated grib, for example using WGRIB/WGRIB2 tools or something like this.

Thanks in advance,

Oriol Ciurana
