unable to read the correct input file using read_radx

This code snippet shows that actually the radar file contains data from a single sweep or elevation, but when I am using read_radx to read the file, it is assembling all the sweep files corresponding to a time instant and producing the data from all the sweeps combined. Even after applying no_assemble=True, no change in the discrepancy has occurred. How can I ensure that read_radx reads only the data from the single sweep available in the input file provided, and do not try to produce the data from the combined 10 sweeps?

@MohitDahliya what is the reason that you are trying to convert your data with radx? And does it fall under this list from the lrose docs?

Actually, my radar data nc files are in FSL format. So, the only way to read them in pyart, according to my knowledge, is through pyart.aux_io.read_radx

@MohitDahliya Gotcha, so does this file contain many sweeps and your trying to just read one sweep? Or is it just one sweep but radx is treating it as a full volume?

[zssherman]

Nvm I see now. So the reader just does a basic radx convert and then reads with pyarts cfradial reader so it could be missing a parameter to read your specific dataset. Could you try one of the xradar readers https://docs.openradarscience.org/projects/xradar/en/stable/importers.html and see if those work? We are depreciating the aux_io module and will eventually drop support for those readers. If those don't work, you might have to try radx convert from outside of py-art and add some parameters in to try to read your file.

@MohitDahliya Ah wait to add to that I just remembered, I recognize the file extension, can you try pyscancf from the open radar science affiliate page:
https://openradarscience.org/affiliated-projects

That might be your best bet

[MohitDahliya]

I have tried pyscancf in the past, but it only converted the radar reflectivity and left out the other polarimetric at that time. I don't know if it has been upgraded since then. However, I will give it a try. I also want to know, which are these xradar readers you are referring to?
