使用python复制netcdf文件

我在 python netcdf: making a copy of all variables and attributes but one找到了这个问题的答案,但我需要改变它以使用我的python / netCDF4版本(Python 2.7.6 / 1.0.4).如果需要添加或减去元素,则需要进行适当的修改.

import netCDF4 as nc

def create_file_from_source(src_file,trg_file):
    src = nc.Dataset(src_file)
    trg = nc.Dataset(trg_file,mode='w')

    # Create the dimensions of the file
    for name,dim in src.dimensions.items():
        trg.createDimension(name,len(dim) if not dim.isunlimited() else None)

    # Copy the global attributes
    trg.setncatts({a:src.getncattr(a) for a in src.ncattrs()})

    # Create the variables in the file
    for name,var in src.variables.items():
        trg.createVariable(name,var.dtype,var.dimensions)

        # Copy the variable attributes
        trg.variables[name].setncatts({a:var.getncattr(a) for a in var.ncattrs()})

        # Copy the variables values (as 'f4' eventually)
        trg.variables[name][:] = src.variables[name][:]

    # Save the file
    trg.close()

create_file_from_source('in.nc','out.nc')

此片段已经过测试.
