NETCDF提取的数据在X轴上镜像

嗨，我有侧面的高程图： https://www.ngdc.noaa.gov/mgg/global/relief/relief/etopo1/data/data/bedrock/grid_register_registered/netcdf/

我想提取数据集的高度。不幸的是，我有一个问题，即NetCDF数据在X轴上镜像！我该如何解决这个问题？

dfl= pd.DataFrame({
    'Latitude' : lat.reshape(-1),
    'Longitude': lon.reshape(-1),
    'Altitude': height.reshape(-1)[0::-1],
    'Value': value.reshape(-1),
});
print(dfl)

Hi I have the elevation map from the side: https://www.ngdc.noaa.gov/mgg/global/relief/ETOPO1/data/bedrock/grid_registered/netcdf/

I want to extract the elevation data of the dataset and change the interpolated values with it. Unfortunately I have the problem that the NetCDF data is mirrored in the X axis! How can I solve this problem?

dfl= pd.DataFrame({
    'Latitude' : lat.reshape(-1),
    'Longitude': lon.reshape(-1),
    'Altitude': height.reshape(-1)[0::-1],
    'Value': value.reshape(-1),
});
print(dfl)
