Near-Earth Space Weather Today

Radiation belts

This is an artist's conception of the Earth and the inner and outer radiation belts that surround it.

Variations in space weather affect Earth's upper atmosphere (mesosphere, thermosphere, and ionosphere). Space weather also impacts the radiation environment in near-Earth space (magnetosphere, plasmasphere, and radiation belts). Check out the links below to find out about current (or the most recent) space weather conditions in near-Earth space and the upper atmosphere.
