Live tracking of weather balloons (radiosondes) around the world
Weather services launch radiosondes on balloons, often twice a day, to measure the atmosphere. SondeHub shows these balloons in flight, with predicted landing spots, using data from amateur radio receivers.
Hobbyists use it to chase and recover fallen sondes; everyone else can watch how weather data is collected.
SondeHub is especially useful for weather watchers.
