Electron precipitation

Electron precipitation is an atmospheric phenomenon that occurs when electrons from the solar wind trapped by the EarthÂ’s magnetosphere enters into the EarthÂ’s upper atmosphere (thermosphere). This is caused because of the interactions between electrons and plasma waves.
Electron precipitation causes the aurorae. Recent researches reveal that it is also responsible for the ozone layer depletion in mesosphere (lower than thermosphere) and climate change. Yet, it is still a mystery how it causes ozone depletion. Researchers created computer simulations using European Incoherent Scatter radar to observe the role of electron precipitation in depleting the ozone layer.
