    First Results from the MATS Satellite Mission (2023)
    In:  XXVIII General Assembly of the International Union of Geodesy and Geophysics (IUGG)
    Details
    Publication Date: 2023-07-07
    Description: Global three-dimensional data are a key to understanding gravity waves in the mesosphere and lower thermosphere. In November 2022, the Swedish MATS satellite was launched into orbit to address this need. MATS applies space-borne limb imaging in combination with tomographic and spectroscopic analysis to study 3D atmospheric structures over a wide range of spatial scales. Measurement targets are O〈sub〉2〈/sub〉 Atmospheric Band airglow in the near infrared, and sunlight scattered from noctilucent clouds in the ultraviolet. This presentation provides an overview over first results from the mission. This includes an outlook on data availability, and examples of usage of the data.

    The MATS satellite mission: Towards gravity wave parameters (2023)
    In:  XXVIII General Assembly of the International Union of Geodesy and Geophysics (IUGG)
    Details
    Publication Date: 2023-07-13
    Description: The Swedish satellite MATS was launched in November 2022. MATS derives three-dimensional temperature fields from the mesosphere and lower thermosphere by observing atmospheric airglow emissions and light scattered off noctilucent clouds. As propagating gravity waves introduce fluctuations in pressure, density and temperature, these measurements can be used to study the wave dynamics of this energetic atmospheric region. To correctly capture the gravity wave spectra, wave-induced perturbations have to be isolated from larger scale fluctuations of the background atmosphere. Based on measurements made by MATS during the initial operational months, as well as synthetic tomography data, we investigate how waves affect the MATS measurements, and how their properties can be derived.
