Seminar entitled (High Frequency Active Auroral Research Program)

On Thursday, 12/12/2013 Asst. Prof. Dr. Mohammed Najm Abdullah presented a seminar under the title of “High Frequency Active Auroral Research Program” this seminar has concentrated on:
HAARP stands for The High Frequency Active Auroral Research Program, is an American program focused on the study and investigation of upper atmospheric and solar-terrestrial physics and Radio Science. The HAARP program operates a major Arctic ionosphere research facility on an Air Force owned site located in Gakona, Alaska. Principal instruments installed at the HAARP Research Station include a high power, high-frequency (HF) phased array radio transmitter (known as the Ionosphere Research Instrument (IRI),see fig(1), used to stimulate small, well-defined volumes of ionosphere, and a large and diversified suite of modern geophysical research instruments including an HF ionosonde, ELF and VLF receivers, magnetometers, riometers, a UHF diagnostic radar and optical and infrared spectrometers and cameras which are used to observe the complex natural variations of Alaska's ionosphere as well as to detect artificial effects produced by the IRI. Future plans include completion of the UHF radar to allow measurement of electron densities, electron and ion temperatures, and Doppler velocities in the stimulated region and in the natural ionosphere using incoherent scatter techniques.
The seminar has been attended by the department stuff members as well as the postgraduate students.
