Every day, several radiosondes start around the world to measure atmospheric parameters such as temperature, humidity and pressure. They are carried by a weather balloon to heights of 20 to 35 km and then fall back to earth. Since the weather sondes are intended for single use, they are not recovered and thus arouse the interest of the "sonde hunters", who usually receive the data themselves and then search for the sondes that have landed. Since not everyone has the necessary receiving equipment and knowledge, we offer a live map and archive of the sondes that are easily accessible.
