摘要

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.
