Ilmalennot

Ilmalennot, also known as weather balloons, are unmanned, high-altitude balloons used for meteorological observations. They are typically made of latex or synthetic rubber and are filled with a lifting gas, such as helium or hydrogen. Weather balloons are launched from ground stations and rise into the atmosphere, carrying instruments that measure various atmospheric parameters.

The primary purpose of weather balloons is to collect data on temperature, pressure, humidity, and wind speed and direction at different altitudes. This information is crucial for weather forecasting, climate research, and atmospheric studies. The balloons can reach altitudes of up to 30 kilometers (19 miles) before bursting due to the decreasing atmospheric pressure.

Once the balloon bursts, a small parachute attached to the instrument package allows it to descend safely back to the ground. The instruments are often equipped with a radio transmitter that sends data to a receiving station in real-time, providing immediate weather information. Weather balloons are an essential tool in meteorology, offering valuable insights into the Earth's atmosphere and helping to improve weather prediction models.
