SA006:
RF Ionospheric Modification


Possible Alternate Format: If this session is allocated an oral session, the convener can choose to have lightning style presentations that are quicker and more focused than a traditional session. Learn more


Session ID#: 24758

Session Description:
HAARP and the Arecibo – HF (High frequency) Facility are restarting operations. HAARP is the most powerful and flexible instrument, with sweeping frequencies and multi-beam modes, located at high-latitude. Arecibo has the largest gain, up to 26 dB, with the advantages of being (1) located below a mid-latitude dense ionosphere that does not vanish after sunset, and (2) collocated next to the Arecibo incoherent scatter radar and other sensible radio and optical instrumentation. Radio frequency (RF) ionospheric modification experiments performed at these establishments during the last two years are revealing unique and complex interactions between the powerful HF transmissions and the natural ionosphere. Structured HF-enhanced plasma and ion lines, artificial airglow, radio scintillations are regular features in the data. This session invites experimenters to present results and explore the potential of new operations at the two facilities, as well to potential users to explore the capabilities of the two facilities.
