使用的是新数据的读取方法
f = cinrad.io.StandardData('D:\data\Radar\Z_RADR_I_Z9411_20230308080400_P_DOR_SAD_CAR_250_230_NUL_FMT.bin.bz2')

数据命名规范

你这个并不是基数据，不能用StandardData

>>> f = cinrad.io.level3.StandardPUP('Z_RADR_I_Z9411_20230308080400_P_DOR_SAD_V_500_115_15_FMT.bin.bz2')
>>> data = f.get_data()
>>> print(data)

目前StandardPUP只支持一部分ROSE产品，格点化的数据都是无法读的
