AE22A:
Ionospheric Modification by Lightning, Solar Flux, and Active Experiments I


Session ID#: 8874

Session Description:
The ionosphere is known to be modified from its ambient conditions by several thunderstorm-related phenomena including the EMP and quasi-static fields from lightning, and thunderstorm-driven gravity waves.  Ionospheric modification also results from solar disturbances including flares and eclipses.  Many observational techniques exist, including 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.
