Can you please share the file you're parsing here? (Zipping it should allow you to attach it to this GitHub issue.)

If you're unable to do that, can you at least tell me the site and date/time? That way I can go find it and try to replicate the problem.

Sorry, I can't give you the test data and the download data link, radar data in China parsing will have a lot of problems. I hope you can write more specific parameters of Level3File in the official document, so that I can check and solve.

[dopplershift]

You can find the official documentation for the NEXRAD product file format, which is what Level3File follows, here. Best of luck.

Closing since there's not a bug in MetPy's code demonstrated here.

ok, thanks.
