Software and data credits
The core of this site is its own code and its own data: telemetry arrives here straight from APRS receivers and listening stations. Part of the telemetry is supplemented by SondeHub, with which the site also exchanges information about recovered sondes; the libraries and tools used on the pages come from outside as well. A full list of those sources, together with their licenses, is given below.
