从没有纬度/经度变量的NetCDF中提取纬度/经度

标签: python netcdf matplotlib-basemap

我有一个NetCDF文件(ERO),它没有纬度/经度作为显式变量。当我致电ERO.variables.keys()时,它将返回

odict_keys(['FCST_ERO_Surface_FULL', 'OBS_ALL_A365324_FULL_MAX_49'])

当我致电ERO.dimensions.items()时,它将返回

('lat', <class 'netCDF4._netCDF4.Dimension'>: name = 'lat', size = 276)
('lon', <class 'netCDF4._netCDF4.Dimension'>: name = 'lon', size = 721)

当我致电ERO时,它会返回

<class 'netCDF4._netCDF4.Dataset'>

这些经纬度变量显然存在,但是我不知道如何访问它们以在底图上可视化它们。我看过的每个NetCDF /底图教程都使用具有lat和lon变量的NetCDF文件。希望我能清楚地解释这一点,任何帮助将不胜感激!
