About the Work:

The largest distrubances of the terrestrial space environment are typically associated with magnetic storms. The events occur when coronal mass ejections (i.e. when relatively dense material from the some is thrown out into space) and impact on the Earth's magnetic field. These storm events lead to major distortions of the terrestrial magnetic field (which can affect power transmission on Earth), and massive changes in the particles environment around the Earth that can be a signficiant radiation hazard, and lead to the loss of thousands of tonnes of Earth's atmosphere. These events are measured by several NASA spacecraft, and are then modeled in detailed to better understand our terrestrial space environment and how it changes under the influence of variable solar wind conditions. Below are results from one such case study.
