Specification of Nighttime Ionospheric Irregularities: Occurrence, Spatial, and Dynamic Properties
Abstract
The primary objective of this program is to develop algorithms to automatically classify images of the nighttime ionosphere and the structure that occurs therein. We will use these algorithms, as well as hand-verified classifications, to construct climatologies of these structures in the Pacific and South American sectors using a multi-year database. The climatologies will allow for a more complete understanding of when and where these irregularities occur and their effects on trans-ionospheric radio wave propagation. From the classified images, we will study the spatio-dynamical properties of the structures in the images and how they relate to disturbances in trans-ionospheric radio wave propagation. A secondary objective is to conduct a ground campaign in New Mexico to study the linkage between lightning, gravity waves in the mesosphere, and the occurrence of mid-latitude structure in the ionosphere. This will provide valuable insights into the linkage of different atmospheric regions and the upward coupling of energy which is believed to have a significant impact on the ionosphere.
