Retrieval of Intrinsic Mesospheric Gravity Wave Parameters Using Lidar and Airglow Temperature and Meteor Radar Wind Data
We analyse gravity waves in the upper-mesosphere, lower-thermosphere region from high-resolution temperature variations measured by the Rayleigh lidar and OH temperature mapper. From this combination of instruments, aided by meteor radar wind data, the full set of ground-relative and intrinsic gravi...
