The inimitable Weatherlawyer will take a look at Winkipedio's takeon this some time in the not too distant:
From Wikipedia, the free encyclopedia
The
High Frequency Active Auroral Research Program (
HAARP) was initiated as an
ionospheric research program jointly funded by the
US Air Force, the
U.S. Navy, the
University of Alaska Fairbanks, and the
Defense Advanced Research Projects Agency (DARPA).
[1] It was designed and built by
BAE Advanced Technologies
(BAEAT). Its original purpose was to analyze the ionosphere and
investigate the potential for developing ionospheric enhancement
technology for radio communications and surveillance.
[2] As a university-owned facility HAARP is a high-power, high-frequency transmitter used for study of the ionosphere.
The most prominent instrument at HAARP is the Ionospheric Research Instrument (IRI), a high-power
radio frequency transmitter facility operating in the
high frequency (HF) band. The IRI is used to temporarily excite a limited area of the
ionosphere. Other instruments, such as a
VHF and a
UHF radar, a
fluxgate magnetometer, a digisonde (an
ionospheric sounding device), and an induction magnetometer, are used to study the physical processes that occur in the excited region.
Work on the HAARP facility began in 1993. The current working IRI was completed in 2007; its prime contractor was
BAE Systems Advanced Technologies.
[1]
As of 2008, HAARP had incurred around $250 million in tax-funded
construction and operating costs. In May 2014, it was announced that the
HAARP program would be permanently shut down later in the year.
[3] After discussions between the parties, ownership of the facility and its equipment was transferred to the
University of Alaska Fairbanks in August 2015.
[4]
HAARP is a target of
conspiracy theorists, who claim that it is capable of
"weaponizing" weather.
Commentators and scientists say that advocates of this theory are
"uninformed", as claims made fall well outside the abilities of the
facility, if not the scope of natural science.
[5][6]
History
The HAARP program began in 1990. Republican
Ted Stevens, U.S. senator from Alaska, helped win approval for the facility,
[7] whose construction began in 1993.
In early May 2013, HAARP was temporarily shut down, awaiting a change
between contractors to operate the facility. In July 2013, HAARP
program manager James Keeney said, "
Defense Advanced Research Projects Agency (DARPA) is expected on site as a client to finish up some research in fall 2013 and winter 2014."
[8][9] 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.
[10]
In May 2014, the Air Force announced that the HAARP program would be shut down later in 2014.
[3][11]
While experiments ended in the summer of 2014, the complete shutdown
and dismantling of the facility was postponed until at least May 2015.
[12]
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.
[13]
Project overview
The HAARP project directs a 3.6
MW signal, in the 2.8–10
MHz region of the HF (high-frequency) band, into the
ionosphere.
The signal may be pulsed or continuous. Effects of the transmission and
any recovery period can be examined using associated instrumentation,
including VHF and UHF radars, 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.
[14]
The project was originally funded by the
Office of Naval Research and jointly managed by the ONR and
Air Force Research Laboratory,
with principal involvement of the University of Alaska Fairbanks. Many
other US universities and educational institutions were involved in the
development of the project and its instruments, namely the
University of Alaska Fairbanks,
Stanford University,
Penn State University (ARL),
Boston College,
UCLA,
Clemson University,
Dartmouth College,
Cornell University,
Johns Hopkins University,
University of Maryland, College Park,
University of Massachusetts Amherst,
MIT,
Polytechnic Institute of New York University, and the
University of Tulsa.
The project's specifications were developed by the universities, who
continued to play a major role in the design of future research efforts.
According to HAARP's original management, the project strove for
openness, and all activities were logged and publicly available, a
practice which continues under the University of Alaska Fairbanks.
Scientists without security clearances, even foreign nationals, were
routinely allowed on site, which also continues today. HAARP hosts an
open house annually, during which time any civilian can tour the entire
facility. In addition, scientific results obtained using HAARP are
routinely published in major research journals (such as
Geophysical Research Letters, or
Journal of Geophysical Research), written both by university scientists (American and foreign) and by
U.S. Department of Defense research lab scientists..
Research
HAARP's main goal is basic science research in the uppermost portion of the
atmosphere, termed the
ionosphere. Essentially a transition between the atmosphere and the
magnetosphere,
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
EISCAT near
Tromsø,
Norway. There, scientists pioneered exploration of the ionosphere by
perturbing it with radio waves in the 2–10 MHz range, and studying how
the ionosphere reacts. HAARP performs the same functions but with more
power and a more flexible and agile HF beam.
Some of the main scientific findings from HAARP include:
- Generating very low frequency radio waves by modulated heating of the auroral electrojet, useful because generating VLF waves ordinarily requires gigantic antennas
- Generating weak luminous glow (measurable, but below that visible with a naked eye) from absorbing HAARP's signal
- Generating extremely low frequency
waves in the 0.1 Hz range. These are next to impossible to produce any
other way, because the length of an antenna is dictated by the
wavelength of the signal it emits or receives.
- Generating whistler-mode VLF signals that enter the magnetosphere and propagate to the other hemisphere, interacting with Van Allen radiation belt particles along the way
- VLF remote sensing of the heated ionosphere
- Plasma line observations
- Stimulated electron emission observations
- Gyro frequency heating research
- Spread F observations (blurring of ionospheric echoes of radio waves due to irregularities in electron density in the F layer)
- High velocity trace runs
- Airglow observations
- Heating induced scintillation observations
- VLF and ELF generation observations[15]
- Radio observations of meteors
- Polar mesospheric summer echoes (PMSE) have been studied, probing the mesosphere using the IRI as a powerful radar, and with a 28 MHz radar and two VHF radars at 49 MHz and 139 MHz. The presence of multiple radars spanning both HF and VHF
bands allows scientists to make comparative measurements that may
someday lead to an understanding of the processes that form these
elusive phenomena.
- Research into extraterrestrial HF radar echos: the Lunar Echo experiment (2008).[16][17]
- Testing of Spread Spectrum Transmitters (2009)
- Meteor shower impacts on the ionosphere
- Response and recovery of the ionosphere from solar flares and geomagnetic storms
- The effect of ionospheric disturbances on GPS satellite signal quality
- Producing high density plasma clouds in Earth's upper atmosphere[18]
Research conducted at the HAARP facility has allowed the US military
to perfect communications with its fleet of submarines by sending radio
signals over long distances.
[19][20]
Instrumentation and operation
The main instrument at HAARP is the Ionospheric Research Instrument (IRI). This is a high-power, high-frequency
phased array radio
transmitter with a set of 180
antennas, disposed in an array of 12x15 units that occupy a rectangle of about 30–40 acres (12–16 hectares).
[21][22] The IRI is used to temporarily energize a small portion of the
ionosphere. The study of these disturbed volumes yields important information for understanding natural ionospheric processes.
During active ionospheric research, the signal generated by the transmitter system is delivered to the
antenna array
and transmitted in an upward direction. At an altitude between 70 to
350 km (43 to 217 mi) (depending on operating frequency), the signal is
partially absorbed in a small volume several tens of kilometers in
diameter and a few meters thick over the IRI. The intensity of the
HF
signal in the ionosphere is less than 3 µW/cm², tens of thousands of
times less than the Sun's natural electromagnetic radiation reaching the
earth and hundreds of times less than even the normal random variations
in intensity of the Sun's natural
ultraviolet
(UV) energy which creates the ionosphere. The small effects that are
produced, however, can be observed with the sensitive scientific
instruments installed at the HAARP facility, and these observations can
provide information about the dynamics of
plasmas and insight into the processes of solar-terrestrial interactions.
[23]
Each antenna element consists of a crossed
dipole that can be polarized for linear,
ordinary mode (O-mode), or
extraordinary mode (X-mode) transmission and reception.
[24][25]
Each part of the two section crossed dipoles are individually fed from a
specially designed, custom-built transmitter that operates at very low
distortion levels. The
Effective Radiated Power
(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. However, 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.
There are other geophysical instruments for research located at the HAARP facility. Some of them are:
- A fluxgate magnetometer built by the University of Alaska Fairbanks Geophysical Institute, available to chart variations in the Earth's magnetic field. Rapid and sharp changes of the magnetic field may indicate a geomagnetic storm.
- A digisonde
that can provide ionospheric profiles, allowing scientists to choose
appropriate frequencies for IRI operation. The HAARP makes current and
historic digisonde information available online.
- An induction magnetometer, provided by the University of Tokyo, that measures the changing geomagnetic field in the Ultra Low Frequency (ULF) range of 0–5 Hz.
The facility is powered by a set of five (5) 2500 kilowatt generators being driven by EMD 20-645-E4 diesel locomotive engines.
Site
The HAARP site was constructed in three distinct phases:
[27]
Well that was informative.
250 million dollars worth of original purpose analysis of the ionosphere and investigation
of the potential development and ionospheric enhancement technology for radio communications and ...surveillance.
Is that why it was dropped, the enhancement... since when was it
