Weather Balloon Operations and Data Collection

The video tutorial explains the upper air program at the National Weather Service, highlighting its role in atmospheric sampling. It details the process of preparing and launching weather balloons, including the use of helium and hydrogen, and the conditions under which launches occur. The preparation of radiosondes, ensuring their functionality, and the importance of GPS data are covered. The video also describes the balloon launch process, data collection, and the subsequent quality control and application of this data in weather forecasting.

What is the primary purpose of the Upper Air Program at the National Weather Service?
