Save Output as netCDF (.nc) file with parcels version 2.4.2 or more

[BenOwusu084]

Hi I am working with the version 2.4.2 of parcels and I have issues saving output file as a netCDF file. It throws an error that tells that the output file cannot be written as a .nc in this version of parcels but as a .zarr file. It works well when I save it as a .zarr file however I would like to save the output file as a .nc file instead of a zarr file. I know I have an option to downgrade the version of parcels to 2.0.0. Could someone please tell me how I can downgrade to a lower version which allows output file to be saved as .nc or if there's a way around it with the upgraded version 2.4.2 which I am using now. I would really appreciate this. Thanks

Hi @BenOwusu084, you can easily change the zarr file to netcdf using something like below

import array as xr
ds = xr.open_zarr("FILENAME.zarr")
ds.to_netcdf("FILENAME.nc")
