Reporting a Fallen Radiosonde

Meteorological radiosondes are white labeled boxes (see the photo on the right for examples of labels) launched by the Japan Meteorological Agency (JMA) for the purposes of aerological observation. The Agency needs to collect fallen radiosondes; anybody finding one is asked to kindly contact JMA by calling the number on the label.

Other organizations that use radiosondes include the Ministry of Defense, universities, research institutes and private corporations in the meteorological field. If you find a radiosonde and are able to identify where it came from, contact the relevant organization. If its origin is unclear, or if you find an inflated balloon, in the interests of safety refrain from touching it and contact the police.
