In the hills of Tirbin Circle at Leparada District of Arunachal Pradesh, a damaged spy drone, identified as a radiosonde, was found on July 18. Local residents reported the discovery, raising significant concerns about national security.
The radiosonde, which crashed in the area’s hilly terrain, is a small instrument typically attached to a hydrogen or helium balloon. It collects vital meteorological data such as temperature, pressure, and humidity during its flight.
The India Meteorological Department (IMD) confirmed that this radiosonde was launched from the Mohanbari weather station. “It was deployed from the Jalpaiguri station to gather upper-level atmospheric data,” an IMD spokesperson clarified.
Radiosondes are essential tools for upper-air observation, providing critical data up to 35 kilometers above the Earth’s surface. This information is indispensable for accurate weather forecasting and climate change monitoring.
