Colony formation in a synchronized Scenedesmus could be controlled by the addition of 0.05% Na3 citrate or 85 μM EDTA to modified Bristol's medium. No unicells were formed; only S. quadricauda-like or S. longispina-type colonies were observed in you

Three-dimensional simulations show the ELF (extremely low frequency) radiation generated by heating the high-latitude D region and modulating the polar electrojet The simulations use a time-varying current perturbation in the D region. The ELF radiat

We report experimental results from the high-power auroral simulation facility showing that the lower D region can be heated so as to produce either a single, narrowband ELF/VLF radiation signal at the modulation frequency or a signal containing the

Three different types of optical phenomena have been observed at high altitude above thunderstorms: an enhanced airglow (“elves”) at roughly ∼90 km; a reddish glow (“sprites”) from 50 to 90 km; and an upward moving, bluish emission (“jets

Electromagnetic pulses (EMP) driven by lightning can cause breakdown of the neutral atmosphere in the lower D-region. Using a computer simulation model, we study the dependence of the breakdown on the pulse strength, the orientation of the lightning

A model for ionospheric density structures at the O+ ion gyroradius induced by the Arecibo heater during the recent El Coqui campaign has been developed. We find that (1) these density structures can be accounted for by the parametric decay of the hi

Large lightning discharges can drive electromagnetic pulses that cause breakdown of the neutral atmosphere between 80 and 95 km leading to order of magnitude increases in the plasma density. The increase in the plasma density leads to increased refle

The propagation of electromagnetic waves parallel to the magnetic field in the nightside Venus ionosphere is presented in a theoretical and numerical analysis. The model assumes a source of electromagnetic radiation in the Venus atmosphere, such as t
