[Tanmay Sarkar]

The option what I mentioned earlier is working well.

Thanks

Ok sir,

Sorry for delayed reply. I missed your mail. This is nothing but our NCAP simulation files. You can take any sector *.nc file for any species.

I have one more Idea, that I am going to try.

I will convert the files to *.grd(grads format) then for first 12 timestep I will write another *.grd file. Then I will merge two file (new one and the old one) using cat command in Linux.

I will try and let you know.

Dear Tammy

Is it possible for you to share your netcdf file? If the sige is big then cut it to a smaller domain by cdo sellonlatbox.

I will check it and reply accordingly.

Dear Sir,
Thank you so much for your reply. I have used this option. It is creating merged *.nc file. But that merged file is not opening using GrADS. It is giving some error saying "time unit has too small and increment".
Don’t know why I am not able to visualize. That why I am confused.

Dear Tanmoy
I don't think it's easier in grads and consequently it is problematic to write multi-timestep netcdf file in grads. However, it's very easy to implement using cdo (as you told you have corresponding netcdf file). The procedure will be the following:
Lets suppose you first file name (that having 12 timestep) is file120.nc. Then cdo seltimestep,1/12 file120.nc first12.nc cdo mergetime file120.nc first12.nc file132.nc

Now, file132.nc will contain 132 timesteps where first 120 timesteps will be from file120.nc (original) and rest 12 timestep will be from first12.nc (first 12 timestep of file120.nc).

I hope it will solve your problem.

Cheers!!!!!!

Best
Suman
