Abstract:

In this work, we carried out studies of satellite and ground-based data and performed basic research on the currents, fields, and plasmas in the upward and downward current systems of the Earths magnetosphere when turbulence is present and when turbulence is neglected or absent. In this way, we seek to improve the capability of the Air Force AF to specify and predict the state of the plasma in the coupled magnetosphere-ionosphere M-I system. It is well known that perturbations of the near-Earth space environment can disrupt important AF systems and thereby interfere with global command, control,communication, intelligence, surveillance, and reconnaissance procedures. Based on our studies, we developed four models and computer codes based on these models. The models describe the intermediate temporal and spatial evolution of the upward and downward Birkeland currents when turbulence is present and when turbulence is neglected or absent. We have documented and will provide the computer codes to the AF and other scientific users upon request.
