使用 netCDF4 从带有 Python 的 NETCDF 文件中提取名称

Question

我一直在摆弄 netCDF4 package 一段时间，无论我尝试什么，我都无法加载变量名。 我会告诉你我的意思。 我写的简单代码如下：

import netCDF4 as netcdf
import numpy as np

f = netcdf.Dataset("pressureOutput/QOUT_500.Netcdf","r")
   
variablesList = f.variables

print(variablesList)

控制台上的output为：

{'variables0': <class 'netCDF4._netCDF4.Variable'>
float64 variables0(dim0)
    name: u
unlimited dimensions: 
current shape = (163840,)
filling on, default _FillValue of 9.969209968386869e+36 used, 'variables1': <class 'netCDF4._netCDF4.Variable'>
float64 variables1(dim0)
    name: v
unlimited dimensions: 
current shape = (163840,)
filling on, default _FillValue of 9.969209968386869e+36 used, 'variables2': <class 'netCDF4._netCDF4.Variable'>
float64 variables2(dim0)
    name: rho
unlimited dimensions: 
current shape = (163840,)
filling on, default _FillValue of 9.969209968386869e+36 used, 'variables3': <class 'netCDF4._netCDF4.Variable'>
float64 variables3(dim0)
    name: p
unlimited dimensions: 
current shape = (163840,)
filling on, default _FillValue of 9.969209968386869e+36 used, 'variables4': <class 'netCDF4._netCDF4.Variable'>
float64 variables4(dim0)
    name: YH2
unlimited dimensions: 
current shape = (163840,)
filling on, default _FillValue of 9.969209968386869e+36 used, 'variables5': <class 'netCDF4._netCDF4.Variable'>
( MORE OUTPUT)
(...)
(...)
filling on, default _FillValue of 9.969209968386869e+36 used, 'variables24': <class 'netCDF4._netCDF4.Variable'>
float64 variables24(dim0)
    name: heatRelease
unlimited dimensions: 
current shape = (163840,)
filling on, default _FillValue of 9.969209968386869e+36 used}

可以看到，变量“variables0”有一个名为 name 的属性，应该是 output u。 我想为每个变量（u、v、rho、p 等）检索此信息。 但是，如果我尝试

f['variables0'].name

我得到“variables0”作为 output。 如何从文件中检索此信息？

您应该能够通过将其转换为列表来解决此问题：

list(variablesList)
