Abstract
The objective of this investigation isto identify and understand the small-scale atmospheric perturbations with a horizontal scale of a few tens of meters, based on a novel Na imager. These extremely small perturbations in this altitude range are believed to contribute considerably to the dynamics in the upper mesosphere and lower thermosphere, ranging between ~ 80 to 110 km. By changing the intensity of these Na images to mesospheric Na number density, we can derive the amplitudes of these perturbations based on the Na mixing ratios that provides a direct measure of the perturbation magnitudes. The perturbations of such scale are rarely detected but are essential to the advancement of our knowledge and technology: further knowledge and understanding of these perturbations have a wide variety of applications, ranging from LIDAR systems and adaptive optics.
