Retrieve.kdp_maesake unexpected output problem with Py-ART

[Woutv]

Hello

I am trying to create KDP values from PhiDP values from a Radar. The radardata I can extract are .VOL files will not be compatible with Py-ART. So I wrote a code to transform the file structure so that it can be stored as a Py-ART radar object construction. I think I do that right because when opening the file, the data is present. Now when I run the pyart.retrieve.kdp_maesaka funstion, the KDP outcome is everywhere 0.002.

What could be the problem and how could it be fixed?
Thanks for the help

Hi Wout, a related question: do you know if the routine pyart.retrieve.kdp_maesaka takes care of phase folding? or do we need to correct it beforehand?

You likely need to unfold the PhiDP first, I would recommend trying that
