Up, Up and Away: How NIST Research Helped Improve Weather Balloon Forecasting While we think of balloons as a fun party accessory, they also play an important role in weather forecasting. Sunday is National Balloons Around the World Day, a day to celebrate both the whimsical and scientific side of balloons.

Nearly 90 years later, the devices, known as radiosondes, are still used today. |
