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.
[17]:
swp.DBZH.sortby("time").plot(x="range", y="time", add_labels=False)
[17]:
<matplotlib.collections.QuadMesh at 0x7f40ddb4a8d0>

[18]:
fig = pl.figure(figsize=(5, 5))
pm = swp.DBZH.wrl.vis.plot(proj={"latmin": 3e3}, fig=fig)

Mask some values#
[19]:
swp["DBZH"] = swp["DBZH"].where(swp["DBZH"] >= 0)
swp["DBZH"].plot()
[19]:
<matplotlib.collections.QuadMesh at 0x7f40dd512990>

Export to ODIM and CfRadial2#
[20]:
xd.io.to_odim(vol, "gamic_as_odim.h5")
xd.io.to_cfradial2(vol, "gamic_as_cfradial2.nc")
Import again#
[21]:
vola = xd.io.open_odim_datatree("gamic_as_odim.h5")
display(vola)
