Export Data

This page focuses on export workflows. For the public writer and object-method list, see IO API and PRD API.

pycwr 1.0.4 does not limit export to Py-ART anymore.

Recommended object-style export

radar.to_pyart_radar(...)
radar.to_xradar(...)
radar.to_wsr98d(...)
radar.to_nexrad_level2_msg31(...)
radar.to_nexrad_level2_msg1(...)

Function-style writers are also available:

from pycwr.io import (
    write_wsr98d,
    write_nexrad_level2_msg31,
    write_nexrad_level2_msg1,
)

from pycwr.io import read_auto

radar = read_auto("./data/file.bin.bz2")
pyart_radar = radar.to_pyart_radar()

If Py-ART is installed, you can continue and write CfRadial:

import pyart
pyart.io.write_cfradial("./cfradial.nc", pyart_radar)

radar.to_wsr98d("./export.bin")
radar.to_nexrad_level2_msg31("./export_msg31.ar2v")
radar.to_nexrad_level2_msg1("./export_msg1.ar2v")

WSR98D export is mainly used for project round-trip and compatibility verification
NEXRAD export is mainly for interoperability with Py-ART and external workflows
Corrected fields and raw fields remain separate variables inside PRD
When exporting to standard interfaces, pycwr chooses a suitable source field according to the current public rules
