将NetCDF4变量保存为它自己的NetCDF4文件

import netCDF4 as nc

dataset = nc.Dataset('path/to/original_file.nc', 'r')

variable = dataset.variables['variable_name']

new_dataset = nc.Dataset('path/to/new_file.nc', 'w', format='NETCDF4')

for dim_name, dim in dataset.dimensions.items():
    new_dataset.createDimension(dim_name, len(dim))

new_variable = new_dataset.createVariable('variable_name', variable.dtype, variable.dimensions)

new_variable[:] = variable[:]

for attr_name in variable.ncattrs():
    new_variable.setncattr(attr_name, variable.getncattr(attr_name))

dataset.close()
new_dataset.close()
