Weather Balloon Launches With Video

NWS Duluth played a part in the 2013 Balloon Festival by launching weather balloons with local middle school students. 
Every day around 800 locations across the globe launch weather balloons.  Most of launched twice a day; at 0000 UTC and 1200 UTC (6:00 am and 6:00 pm CST) to collect information on current atmospheric conditions.  The information gathered from these weather balloons (commonly called radiosondes) is used for many weather applications.

Hermantown Middle School's 8th grade science class launched a watehr balloon on Saturday and  Sunday's launch was done by Marshall School's 6th grade science class.  Visits and presentations to the schools by NWS meteorologists prepared the students for the launches.  The data collected by the weather sensors will be used to enhance their weather studies.

Radiosonde observations are applied to a broad spectrum of efforts. Data applications include:

- Input for computer-based weather prediction models;

- Local severe storm, aviation, and marine forecasts;

- Weather and climate change research;

- Input for air pollution models;

- Ground truth for satellite data

For the launches, a GoPro camera attached to the payload filmed the balloons ascent and descent. A GPS was also attached to track the balloon in the sky, and to also help us retrieve the GoPro after the weather balloon burst and fell back to earth.

Thank you to the St. Louis County Volunteer Search and Rescue crew for retrieving the payloads! We know it wasn't easy, but we sure appreciate it!
