SDK to access SondeHub open data

Project description

Simple realtime streaming SDK for sondehub.org V2 API.

sondehub.Stream(sondes=["serial number"], on_message=callback)

If no sondes list is provided then all radiosondes will be streamed.

On message callback will contain a python dictonary using the Universal Sonde Telemetry Format

sondehub.Stream().add_sonde(serial)
sondehub.Stream().remove_sonde(serial)

Adds or removes a radiosonde from the filter

Example Usage

import sondehub

def on_message(message):
    print(message)

test = sondehub.Stream(sondes=["R3320848"], on_message=on_message)
#test = sondehub.Stream(on_message=on_message)
while 1:
    pass

Advanced Usage

Manual usage of the Paho MQTT network loop can be obtained by using the loop, loop_forever, loop_start and loop_stop functions, taking care to ensure that the different types of network loop aren't mixed. See Paho documentation here.

test = sondehub.Stream(on_message=on_message, sondes=sondes, auto_start_loop=False)
test.loop_forever()

Open Data Access

A basic interface to the Open Data is a available using sondehub.download(serial=, datetime_prefix=). When using datetime_prefix only summary data is provided (the oldest, newest and highest frames)

import sondehub
frames = sondehub.download(datetime_prefix="2018/10/01")
frames = sondehub.download(serial="serial")
