Earth's atmosphere still holds many secrets for science, but with the latest satellite launches and long-running observations from the ground, we are now gathering far more and better quality data about the weather and climate than ever before.
We begin our story with the team at the Hohenpeißenberg weather station in Bavaria, a historic spot where weather balloons have been launched every week for the past 50 years. The information these balloons gather is vital to feed weather and climate models, and measure Earth's high altitude ozone layer.
