High-altitude inflatable spheres, typically constructed from latex or synthetic rubber and filled with lighter-than-air gases like helium or hydrogen, are available for purchase. These spheres carry instruments called radiosondes that collect atmospheric data such as temperature, humidity, wind speed, and direction. A typical setup includes the balloon itself, the radiosonde, a parachute for recovery, and sometimes a ground station for data reception.
Acquiring these research tools allows for crucial atmospheric measurements contributing significantly to meteorological forecasting, climate research, and educational purposes. Historical use dates back to the late 19th century, evolving from simple manned flights to sophisticated unmanned systems offering valuable data for understanding and predicting weather patterns and long-term climate trends. This data collection plays a vital role in severe weather prediction and disaster preparedness.
