High-altitude balloon ride offers new perspective for CAIRT

A novel sensor that simulates the measurements that would be taken by one of the proposed satellites vying to be ESA’s eleventh Earth Explorer, has endured an extraordinary journey.

Carried aboard a high-altitude balloon on a four-day voyage from Sweden to Canada, the sensor provides new data that could help to refine the CAIRT mission concept – a mission that aims to unravel the complexities of Earth's atmosphere and enhance our understanding of climate dynamics.
