Radiosondes are small, expendable instrument packages that are suspended below a large balloon inflated with hydrogen or helium gas known as the weather balloon. They transmit air pressure, temperature, relative humidity, and GPS position data each second they are used. They are also connected to a battery-powered, 300 milliwatt radio transmitter so they transfer their data much faster.
Rawinsondes are observations where winds aloft and are obtained by radiosondes. They can be radiosondes or can be a result of radiosonde data but they work the same as radiosondes but are tracked by a radar or radio direction finder. It can project methods of upper-air observation consisting of an evaluation of wind speed and direction, temperature, pressure, and relative humidity.
When the balloon reaches its maximum height, it explodes leading the device to fall a large height from the atmosphere. However, there is an orange parachute to prevent this device from breaking due to it having a possibility to harming the environment and to possibly use these devices again in the future. Most radiosondes however land in the oceans due to most of the stations being on the coasts.
Without radiosondes, we wouldn't be able to calculate weather data to create maps, graphs, and future conditions. Without these devices, we wouldn't even know if it would rain or if there could be snow. This has a very important purpose in today's technology.
