xarray GAMIC backend#
In this example, we read GAMIC (HDF5) data files using the xradar gamic
backend.

Inspect sweep group(s)#
The sweep-groups can be accessed via their respective keys. The dimensions consist of range
and time
with added coordinates azimuth
, elevation
, range
and time
. There will be variables like radar moments (DBZH etc.) and sweep-dependend metadata (like fixed_angle
, sweep_mode
etc.).

Create simple plot#
Using xarray features a simple plot can be created like this. Note the sortby('time')
method, which sorts the radials by time.
For more details on plotting radar data see under Visualization.
