chaos theory and particle size relevant to SRM

Intricate features in the lifetime and deposition of atmospheric aerosol particles

"To illustrate the concepts in the paper, Haszpra has created an online game, called RePLaT-Chaos, that lets players learn the topic of atmospheric advection by creating and testing their own volcanic eruptions.

Haszpra believes her findings can inform future efforts that have been suggested to use sun-reflecting air particles to counteract climate change. She plans to expand on this work by incorporating historical meteorological data and climate models to better understand how the dispersion of particles might change when the climate changes."

Press release:

Floating air particles following disasters and other geological events can have a lasting impact on life on Earth, and a new model drawing on chaos theory looks to help predict how these particles move, with an eye toward applications for geoengineering. Scientists have developed a model for following particles as they travel around the globe. Using it, she has generated maps that can be used to predict how particles will be dispersed above the world.
