how to write to a netcdf file using xarray

#import xarray
import xarray as xr

ds = xr.open_dataset(file_name.nc)

#by now you may have performed some computations and ds is a new dataset

ds.to_netcdf('/directory_to_file/file_name.nc', format='NETCDF4_CLASSIC')

Comment

using xarray to open netcdf data

# Reading and writing netCDF files with xarray requires scipy or the netCDF4-Python library
# to be installed (the latter is required to read/write netCDF V4 files and use the
# compression options described below).


# 1) We can load netCDF files to create a new Dataset using open_dataset():

ds_disk = xr.open_dataset("saved_on_disk.nc")

# print data information
ds_disk
    
    
# 2) We can save a Dataset to disk using the Dataset.to_netcdf() method:
ds.to_netcdf("saved_on_disk.nc")


# Datasets have a Dataset.close() method to close the associated netCDF file.
# However, it’s often cleaner to use a with statement:

# this automatically closes the dataset after use
with xr.open_dataset("saved_on_disk.nc") as ds:
     print(ds.keys())
