THE NATIONAL ACADEMIES

Advisers to the Nation on Science, Engineering, and Medicine

The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences.

The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. C. D. Mote, Jr., is president of the National Academy of Engineering.

The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.

The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. C. D. Mote, Jr., are chair and vice chair, respectively, of the National Research Council.

Preface

At the request of the Department of Defense (Air Force Research Laboratory) and the National Science Foundation (NSF; Directorate for Geosciences/Division of Atmospheric and Geospace Sciences), the Space Studies Board of the National Research Council (NRC) held a workshop on May 20-21, 2013, in Washington, D.C., entitled “The Role of High-Power, High Frequency-Band Transmitters in Advancing Ionospheric/Thermospheric Research.” The workshop provided a forum for information exchange between the comparatively small group of scientists engaged in programs of upper atmospheric research using high-power, high-frequency (HF) radar transmitters (“heaters”) and the larger ITM (ionosphere-thermosphere-magnetosphere) research community. For a variety of reasons—including the different orientations of the Department of Defense, which is primarily interested in applied research related to active ionospheric modification,1 and the civil agencies, principally NSF, which have broader mandates for basic research—these communities have historically viewed themselves as being distinct with limited overlapping interests.

As indicated in the terms of reference (“statement of task”) developed by the sponsors (see Appendix A), the workshop was organized to consider the utility of heaters in upper atmospheric research in general, with a specific focus on the High Frequency Active Auroral Research Program (HAARP) transmitter facility, which is located in Gakona, Alaska. The motivations for the workshop were twofold. First, the sponsors of the workshop were aware of the potential—one that became increasingly apparent during the period between project approval by the NRC in late Spring 2012 and the actual workshop in late Spring 2013—for substantial cutbacks in support by the Air Force for the continuing operation of HAARP.2 Second, NSF’s upper atmosphere research section is considering transfer to Gakona, Alaska, of the AMISR (Advanced Modular Incoherent Scatter Radar) re-locatable modular phased-array radar, located at Poker Flat, Alaska (thus, known as PFISR), for joint research campaigns with the HAARP transmitter and ancillary instruments. Although the original statement of task was never revised, the organizers were keenly aware of the increasing interest among the sponsors for focused discussions on the HAARP facility. The workshop agenda and the preponderance of discussions at the workshop reflect these interests.

The workshop agenda and a list of participants are shown in Appendixes B and C, respectively, and biographical information about the workshop organizing committee is shown in Appendix D. While the committee is responsible for the overall quality and accuracy of the report as a record of what transpired at the workshop, the views contained in the report are not necessarily those of all workshop participants, the committee, or the NRC. It should also be recognized that the report summarizes, but does not evaluate critically, the assertions made by participants of the potential utility for high-power, high-frequency transmitters or the HAARP facility. Finally, although the authors of this summary have attempted to provide context for the often highly technical discussions that took place, the summary is not intended to be a primer on heaters in general, HAARP in particular, or current issues in upper atmosphere research.

__________________

1 The use of high-power transmitters, such as the one located at the HAARP facility, to study the upper atmosphere is called “active ionospheric research.”

2 In fact, the HAARP facility ceased operations shortly after the workshop—due to pending contractor changes and an as yet unfunded need to upgrade the diesel power generators per Environmental Protection Agency regulations—and remains closed at the time of this printing.

Opportunities for High-Power, High-Frequency Transmitters to Advance Ionospheric/Thermospheric Research is the summary of a workshop convened by the Space Studies Board of the National Research Council in May 2013. The request for this workshop was informed by the sponsors' awareness of the possibility that tight budgets would result in the Department of Defense's curtailment or even termination1 of support for the High Frequency Active Auroral Research Program (HAARP), which includes the world's highest-power and most capable high-frequency 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.

Research conducted by the ionospheric modifications community - a community that uses high-frequency 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 non-linear plasma physics processes. The workshop provided a forum for information exchange between the comparatively small group of scientists engaged in programs of upper atmospheric research using high-power high-frequency radar transmitters and the larger ionospherethermosphere-magnetosphere research community.

This report examines the state of the art in active ionospheric and thermospheric research; considers the fundamental research areas in ionospheric science that can be addressed using high-power high-frequency-band transmitters; discusses emerging science questions that might benefit from active ionospheric experiments in the sub-auroral zone; and considers ways to combine similar facilities to perform global ionospheric science. The report also examines research opportunities that might arise from the relocation of the AMISR incoherent scatter radar from the Poker Flat Research Facility in Poker Flat, AK to Gakona, AK, the location of the HAARP facility.
