How to Use a Weather Balloon

In order to get information about the weather or collect atmospheric data, you need to use a weather balloon. This data or information is used by scientists to help make weather predictions and forecasts. There are many different shapes and sizes of weather balloons which you can use. All the instrumentation is attached to the bottom of the weather balloon to collect the information. Follow some simple steps to learn how to use a weather balloon.

Things Required:

– Weather balloon
– Hydrogen or helium
– Radiosonde or another type of recording equipment
– Tether
