Abstract:

Research conducted by the ionospheric modifications IM community -- a community that uses high-frequency HF transmitters to inject energy in the ionosphere and measure its effects using ground and space-based diagnostics -- is focused on understanding the interaction of radio waves with the ionospheric plasma, the local consequences of heating in the ionosphere, and studies of nonlinear plasma physics processes. At the request of the Department of Defense DOD Air Force Research Laboratory AFRL and the National Science Foundation NSF Directorate for GeosciencesDivision of Atmospheric and Geospace Sciences, the Space Studies Board of the National Research Council held a workshop on May 20-21, 2013, in Washington, D.C., entitled The Role of High-Power, High Frequency-Band Transmitters in Advancing IonosphericThermospheric Research. The request for this workshop was informed by the sponsors awareness of the possibility that tight budgets would result in DOD s curtailment, or even termination, of support for the High Frequency Active Auroral Research Program HAARP, which includes the world s highest-power and most capable HF transmitter -- heater -- for ionospheric research. Although the workshop was organized to consider the utility of heaters in upper atmospheric research in general, it had a specific focus on the HAARP transmitter facility, which is located in a remote part of southeastern Alaska.
