Measurement of mesospheric winds using the Michelson Interferometer for Airglow Dynamics Imaging (MIADI)

MIADI images the wind and irradiance fields present in mesospheric airglow signatures using a new implementation of the field widened Michelson technique. The system is unique in its ability to image the mean wind and irradiance as well as the perturbation quantities, allowing for unambiguous gravity wave parameters to be derived using a single optical element. MIADI was installed and tested at the MU radar field site in Shigaraki Japan in 2009. Several nights of observations have been obtained and the initial analysis has been completed. In this presentation, the instrument technique, calibration process and installation/testing will be described and the analysis of the initial wind and irradiance measurements will be presented.
