Investigation of Plasma Phenomena in the Ionosphere Under Natural Conditions and Under Conditions Artificially Perturbed by HAARP
Abstract
During the report period, NorthWest Research Associates (NWRA) conducted ionospheric measurements at several Air Force research and operational locations and analyzed the data collected thereby. The measurements were performed using a variety of radiowave techniques, most involving transionospheric radio propagation, and included observations of ionospheric perturbations via high-power transmissions under the High frequency Active Auroral Research Program (HAARP). Total Electron Content (TEC) from a chain of stations in Alaska were inverted tomographically to produce altitude versus latitude images of plasma density. By these and other means, ionospheric features such as the main F-layer trough and polar patches were characterized for application to Air Force environmental models. Studies of ionospheric scintillation focused on the performance of models for scintillation were conducted. A number of studies were undertaken to develop better means of partitioning GPS TEC data in altitude and to assess uncertainties in TEC derived from GPS observations.
