Hi all,

I have a RHI radar file where I want to unfold the velocities just for one sweep (170 azimuth). I need to perform the correction just over one sweep because some of the data during the 190 azimuth scan is bad. 

The first image attached is the 170 azimuth RHI scan (folded velocity) in which I'm trying to unfold (dealias). I will also attach my code.

Not sure if it's possible to use 'pyart.correct.dealias_region_based()' just on one sweep or not.

Any help will suffice.

Sorry for the late reply, you are correct in that the default behavior of region based dealiasing is to dealias the entire volume. One way to get around that is to create a new radar object with just the sweep that you desire. I modified your example with what I think should work. 

Hope this helps!
