[ncl-talk] netcdf file size question

[Hauss Reinbold]

Hi all,

I’m creating a large netcdf dataset via NCL and I was looking to reduce the file size by reducing the number of decimal places the float values were holding, but it doesn’t look like it worked. In looking into it further, it seems like NCL allocates space in the file by data type, regardless of what value each individual index of an array might have. Is that correct?

I did some looking and couldn’t see a way to reduce file size explicitly other than by changing data type, which I don’t think I can do. Is there a way to reduce the file size of the netcdf file by limiting the number of decimal places? Or is compression or changing the data type my only alternative here?

Thanks for any help on this.
