Radiosondaukset

Radiosondaukset, also known as weather balloons, are unmanned, instrumented packages that are launched into the atmosphere to collect data for weather forecasting and atmospheric research. These devices are typically made of lightweight materials such as latex or synthetic rubber and are filled with helium or hydrogen gas to achieve buoyancy. The instruments carried by radiosondes include sensors for measuring temperature, humidity, pressure, and wind speed and direction.

The launch process involves attaching the radiosonde to a balloon and releasing it from a ground station. As the balloon ascends, the radiosonde transmits data back to the ground station via radio signals. The data is then processed and used to create weather maps and forecasts. Radiosondes can reach altitudes of up to 30 kilometers (19 miles) and can remain aloft for several hours, depending on the atmospheric conditions.

Radiosondes have been in use since the early 20th century and have played a crucial role in advancing our understanding of the atmosphere. They are an essential tool for meteorologists and atmospheric scientists, providing valuable data for weather forecasting, climate research, and atmospheric modeling. Despite their age, radiosondes continue to be an important component of the global observing system, with thousands of launches occurring daily around the world.
