What does this mean?
Dealiasing is the action of correcting issues in velocity sweeps. When you load a Level 2 file and view its velocity data, a lot of the time, the velocity values will seem wrong. There is a process to correct this, and it's called dealiasing. AtticRadar implements two dealiasing algorithms.

The Region Based algorithm was originally developed for use in the python package pyart. I simply rewrote it in JavaScript, for use in AtticRadar. This algorithm is very robust, and is great at dealing with gaps in data, e.g. hurricanes.

The Tornadic algorithm is much better suited for dealing with velocity scans with tornado signatures, or tight rotation in general. The region based algorithm struggles with these cases, so if you find an issue with that algorithm, you should try this one.
