Waves in the Earth's mesosphere, seen in noctilucent clouds over the Netherlands in June 2019.

MATS (Mesospheric Airglow/Aerosol Tomography and Spectroscopy) is a Swedish research satellite designed for studying waves in Earth's atmosphere. Launch occurred on 4 November 2022 from the Rocket Lab Launch Complex 1 at the Mahia Peninsula in New Zealand.[2][3][4]

MATS is planned to study atmospheric waves, providing data for atmospheric models monitoring future changes in the mesosphere, the atmospheric layer 50-100 km above sea level. In particular, MATS is designed to measure noctilucent clouds and atmospheric airglow from oxygen molecules.[5]
