Why Your Weather Sucks

Stratospheric aerosol injection
From Wikipedia, the free encyclopedia
Stratospheric aerosol injection (SAI) solar geoengineering (or solar radiation modification) to reduce global warming. This would introduce aerosols into the stratosphere to create a cooling effect via global dimming

Ionospheric heater/ NEXRAD
From Wikipedia, the free encyclopedia
An ionospheric heater, or an ionospheric HF pump facility, is a powerful radio wave transmitter with an array of antennas which is used for research of plasma turbulence, the ionosphere, and the upper atmosphere.[1]

Objectives and techniques
These transmitters operate in the high frequency (HF) range (3-30 MHz) at which radio waves are reflected from the ionosphere back to the ground. With such facilities a range of plasma turbulence phenomena can be excited in a semi-controlled fashion from the ground, during conditions when the ionosphere is naturally quiet and not perturbed by for example aurora. This stimulus-response type of research complements passive observations of naturally excited phenomena to learn about the ionosphere and upper atmosphere.
