Forecasting volcanic ash in the atmosphere is crucial for aviation, as ash can interfere with aircraft navigational instruments and can even damage engine parts. A new study, using wind data from ESA’s Aeolus mission, highlights the importance of using satellite missions like Aeolus to improve volcanic ash forecasting and ensure aviation safety in the future.
