Re: [ferret_users] Transform 4D to 3D datasets

["FISSEHA G. BERHANE" <fishcivilmu@xxxxxxxxx>]

Hi Verena,

 In Ferret, after extracting the appropriate level, using k=@ave  removes the k-dimension.

le uu = uwnd[k=8]
let u = uu[k=@ave]
save/clobber/file = new_data.cdf   u

Then, new_data.cdf is 3D.

Best

Thank you,
Fisseha

Hi,

I did, but still get the same dimensions 4D,

Finally it works when i'm using NCO command.

Thanks a lot ;)

Hi Verena,

You can save 200 hPa U in new netcdf file, like this:
Assuming that U at 200 hPa is equal to k=1

save/file=u200.nc u[k=1]

Then, the new file u200.nc is 3D.

Bests,

Júnior

Hi Ferret users,

I just wonder is there any possible way to change the dimension in my data from 4D to 3D,

let say i have zonal wind data only at level 200 hPa thus U [time x lev x lat x lon] and i want to remove

the level dimension inside thus later i just have U [time x lat x lon]. Since it only consist of 1 level, i don't need "level" dimension inside my data.

Thanks for your help.
