What is a Radiosonde Parachute?
 

Meteorology stations release balloons into the sky to receive information on pressure, temperature, humidity and wind in the air. The radiosonde device connected to the balloons ascends to a height of 35 km from the ground and transmits the information in the air to the ground station via radio waves during its stay in the air.

 

A parachute is used to prevent the radiosonde device attached to the balloon bursting at a certain altitude from falling randomly.
