Have you found a weather balloon?

Sometimes weather balloons with small white boxes hanging on them can be found on the ground. They are actually radiosondes, which are meteorological devices used to measure temperature, humidity, pressure, wind speed and direction in the upper atmosphere. These instruments are launched by our various customers, such as the national weather institutes, environmental and research organizations.  More information and instructions for disposing the radiosonde.
