The temporary shutdown was described as being due to "a contractor regime change."
Ahtna, Incorporated, the
Alaska Native corporation serving the region of Alaska where the HAARP site is located, was reportedly in talks to take over the facility administration contract from Marsh Creek, LLC.
In May 2014, the Air Force announced that the HAARP program would be shut down later in 2014.
While experiments ended in the summer of 2014, the complete shutdown and dismantling of the facility was postponed until at least May 2015. In mid-August 2015 control of the facility and its equipment was turned over to the University of Alaska Fairbanks, which is making the facilities available for researchers on a pay-per-use basis.

s, HF receivers, and optical cameras. According to the HAARP team, this will advance the study of basic natural processes that occur in the ionosphere under the natural but much stronger influence of solar interaction. HAARP also enables studies of how the natural ionosphere affects radio signals.
The insights gleaned at HAARP will enable scientists to develop methods to mitigate these effects to improve the reliability or performance of communication and navigation systems which would have a wide range of both civilian and military uses, such as an increased accuracy of GPS navigation and advances in underwater and underground research and applications. This may lead, among other things, to improved methods for submarine communication or an ability to remotely sense and map the mineral content of the terrestrial subsurface, and perhaps underground complexes, of regions or countries. The current facility lacks range to be used in regions like the oil-rich Middle East, according to one of the researchers involved, but the technology could be put on a mobile platform.

Scientists without security clearances, even foreign nationals, were routinely allowed on site, which also continues today.

, the ionosphere is where the atmosphere is thin enough that the Sun's X-rays and UV rays can reach it, but thick enough that there are enough molecules present to absorb those rays. Consequently, the ionosphere consists of a rapid increase in density of free electrons, beginning at 70 km, reaching a peak at ~300 km, and then falling off again as the atmosphere disappears entirely by ~1,000 km. Various aspects of HAARP can study all of the main layers of the ionosphere.
The profile of the ionosphere is highly variable, changing constantly on timescales of minutes, hours, days, seasons, and years. This profile becomes even more complex near Earth's magnetic poles, where the nearly vertical alignment and intensity of Earth's magnetic field can cause physical effects like
the aurora.
The ionosphere is traditionally very difficult to measure. Balloons cannot reach it because the air is too thin, but satellites cannot orbit there because the air is too thick. Hence, most experiments on the ionosphere give only small pieces of information. HAARP approaches the study of the ionosphere by following in the footsteps of an ionospheric heater called

(ERP) of the IRI is limited by more than a factor of 10 at its lower operating frequencies. Much of this is due to higher antenna losses and a less efficient antenna pattern.
The IRI can transmit between 2.7 and 10 MHz, a frequency range that lies above the AM radio broadcast band and well below Citizens' Band frequency allocations. HAARP is licensed to transmit only in certain segments of this frequency range. When the IRI is transmitting, the bandwidth of the transmitted signal is 100 kHz or less. The IRI can transmit in continuous waves (CW) or in pulses as short as 10 microseconds (μs). CW transmission is generally used for ionospheric modification, while transmission in short pulses frequently repeated is used as a radar system. Researchers can run experiments that use both modes of transmission, first modifying the ionosphere for a predetermined amount of time, then measuring the decay of modification effects with pulsed transmissions.

ionospheric heating facilities. This was used for a number of successful scientific experiments and ionospheric exploration campaigns over the years.

, tabled a motion for a resolution on the potential use of military-related resources for environmental strategies. The proposal is referred to the Committee on Foreign Affairs, Security and Defense Policy for substantive consideration. Magda Aelvoet, Belgian MEP and President of the Green Group, becomes convinced that HAARP is a secret weapon system. In 1998, the two MEPs, convinced by Begich's theory that HAARP poses a threat to the environment, decided to write a report in which they interviewed only two people — Begich and Rosalie Bertell, head of a Canadian association which also supports the conspiracy theory of chemtrails — the invited representatives of the United States and NATO did not respond. It is on the basis of these two testimonies alone, in which Begich is described as a doctor without having any qualification, that a report by the European Parliament's Committee on Foreign Affairs, Security and Defense Policy relating to the environment, security and foreign policy takes up these assertions and adopts a resolution indicating that "HAARP (High Frequency Active Auroral Research Project) by virtue of its far-reaching impact on the environment to be a global concern and (the European Parliament) calls for its legal, ecological and ethical implications to be examined by an international independent body before any further research and testing."

'' that weather-control conspiracy theories were "completely uninformed," explaining that "there's absolutely nothing we can do to disturb the Earth's eathersystems. Even though the power HAARP radiates is very large, it's minuscule compared with the power of a lightning flash—and there are 50 to 100 lightning flashes every second. HAARP's intensity is very small." Computer scientist David Naiditch characterizes HAARP as "a magnet for conspiracy theorists," saying that HAARP attracts their attention because, "its purpose seems deeply mysterious to the scientifically uninformed."

of conspiracy theories," and said the popularity of conspiracy theories often overshadows the benefits HAARP may provide to the scientific community. Austin Baird writing in the '' Alaska Dispatch'' said, "What makes HAARP susceptible to conspiracy criticism is simple. The facility doesn't open its doors in the same way as other federally funded research facilities around the country, and it doesn't go to great efforts to explain the importance of its research to the public."
