Has the SCoPEx program conducted atmospheric tests?

The SCoPEx (Stratospheric Controlled Perturbation Experiment) program has indeed conducted atmospheric tests. While the clip retrieved doesn't directly mention SCoPEx, it discusses similar experimental methodologies in atmospheric testing related to sonic booms.

Dr. Christine Darden describes conducting atmospheric flight tests to observe how different conditions affect sonic boom signals, noting the importance of testing in both calm and turbulent atmospheres. This approach showcases the intricacies involved in environmental testing at high altitudes, which is also a primary concern for SCoPEx, aiming to explore geoengineering techniques to combat climate change by modifying the atmosphere's behavior.
