Question

我正在尝试提取一些netcdf数据，但出现错误。任何帮助，将不胜感激。

我尝试了data.variables ['instrument_avail']。instrument_A_lat_deg，但这不起作用。还有另一种提取方法吗？

from netCDF4 import Dataset as NetCDFFile

data=NetCDFFile('my_data.nc')
data.variables['instrument_avail']

#this is the result to the above call:

<type 'netCDF4._netCDF4.Variable'>
|S1 instrument_avail()
    instrument_Loc_A_lat_deg: 38
    instrument_Loc_A_lat_min: 5
    instrument_Loc_A_lat_sec: 5
    instrument_Loc_A_lon_deg: -75
    instrument_Loc_A_lon_min: 35
    instrument_Loc_A_lon_sec: 8
unlimited dimensions: 
current shape = ()
filling on, default _FillValue of � used

上面列出了调用data.variables ['instrument_avail']的结果。

我收到以下错误：

data.variables['instrument_avail'].instrument_A_lat_deg
Traceback (most recent call last):

  File "<ipython-input-32-c85db34c651e>", line 1, in <module>

AttributeError: NetCDF: Attribute not found

如何准确获取实际数据； lat_deg，lat_min，lat_sec等？

如何提取netcdf4变量属性？
