@nawendt which version of Py-ART are you using?
1.16.1.post7. It was latest available on the repo at the time.
Thanks @nawendt - it looks like nans are not being dealt with properly.... I am looking into the issue and let we know we have a fix that is ready to test with your dataset. Thank you for providing sample code to reproduce the issue!
Description
Similar to #992, there appears to be a fairly substantial low bias on the wind speeds that get calculated in
vad_michelson
.vad_browning
and the direct level 3 VAD data from a NEXRAD radar show more reasonable values and are more similar to one another. #1428 was suggested to have solved the issue, but it may not be the case based on comparisons I have done.What I Did
Here is some example code to reproduce the problem:
This produces the following comparison:
Test data are attached here: test_data.zip
I also tried simply calling
vad_michelson
andvad_browning
directly with similar results. There were some minor differences noted in thevad_browning
output when not usingcalculate_vad
, but nothing overly concerning. As a general question, however, is it the recommended approach to use a method likecalculate_vad
versus calling the pyART VAD methods directly with a full volume?
