Description

I cant see radar parameters and georeferencing groups

What I Did

import xradar as xd
from open_radar_data import DATASETS

file = DATASETS.fetch("KLBB20160601_150025_V06")

tree = xd.io.open_nexradlevel2_datatree(file)

print(tree.groups)

('/',
 '/sweep_0',
 '/sweep_1',
 '/sweep_2',
 '/sweep_3',
 '/sweep_4',
 '/sweep_5',
 '/sweep_6',
 '/sweep_7',
 '/sweep_8',
 '/sweep_9',
 '/sweep_10')

I think this might resolved with #221.

[syedhamidali]

@aladinor Yes, I installed your data-constructor branch and gave it a try, it is working... Thanks!

[syedhamidali]

Solved in #221

[syedhamidali]

Although @aladinor’s changes resolved the issue with these groups, it turns out they are empty. I think the error lies in the nexrad_level2 reader.

[kmuehlbauer]

Currently there is no mapping between the nexrad metadata and those groups. Nexrad is not the only engine which would need a proper mapping. #221 was the first big step to make this possible at all by making these groups available (even if not filled).

We should keep this issue open until we've worked the different backends mapping.
