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. |
