i was correcting the same radar file using ur code and got following error Cell In[5], line 44 39 vol[“sweep\_end\_ray\_index”].values = sweep\_end\_ray\_index 41 # assign data to wradlib RadarVolume() 42 # now we have everything in place and can extract individual sweeps 43 # this is done via private functions of wradlib, so take with care —\> 44 sweeps = [wrl.io.xarray._assign\_data\_radial(vol, sweep=f"sweep_{i+1}")[0] for i in range(vol.dims[“sweep”])] 45 new\_vol = wrl.io.RadarVolume(engine=“cfradial1”) 46 new\_vol.extend(sweeps) Cell In[5], line 44, in (.0) 39 vol[“sweep\_end\_ray\_index”].values = sweep\_end\_ray\_index 41 # assign data to wradlib RadarVolume() 42 # now we have everything in place and can extract individual sweeps 43 # this is done via private functions of wradlib, so take with care —\> 44 sweeps = [wrl.io.xarray._assign\_data\_radial(vol, sweep=f"sweep_{i+1}")[0] for i in range(vol.dims[“sweep”])] 45 new\_vol = wrl.io.RadarVolume(engine=“cfradial1”) 46 new\_vol.extend(sweeps) AttributeError: module ‘wradlib.io.xarray’ has no attribute ‘\_assign\_data\_radial’ ---

Hi @Jagdish_jena, the example you are following is for an older wradlib version. The example would have to be adapted to work with recent wradlib. Best, Kai [Previous page](https://openradar.discourse.group/t/decoding-error-reading-cfradial1-file/80.md?page=1)
