Session ID#: 15016

Session Description:
The ionosphere is modified from its ambient conditions by a host of geophysical phenomenon, including the EMP from lightning strokes, quasi-static fields from lightning, thunderstorm-driven gravity waves, solar and space weather disturbances, meteor trails, earthquakes, and more. Many techniques exist to observe these perturbations, including optics, VLF remote sensing, GPS TEC, and HF sounding.

Active and controlled experiments to modify the ionosphere have for decades been a promising complement to observations of natural ionospheric modification, turning the ionosphere into an expansive laboratory. Primary techniques include high power radio waves from HF arrays or other ground sources and high altitude particle releases. Physical phenomena stimulated include electron heating, density irregularities, plasma turbulence, optical emissions, ELF/VLF wave generation, and magnetospheric coupling.

We solicit papers presenting observations, modeling, and/or experiments related to ionospheric modification. Papers may focus on natural or active ionospheric modification, or on comparisons of the underlying physics that drive both.
