We now offer the Cool It! card game in our Science Store. Cool It! is the new card game from UCS that teaches kids about the choices we have when it comes to climate change.
This image shows how different types of solar radiation (x-rays to infrared radiation) penetrate into the Earth's atmosphere. It is this solar radiation that ionizes the upper atmosphere, creating the ionosphere.

The Sun's Effect on the Ionosphere

The ionosphere is an invisible region found in the Earth's atmosphere. When the Sun is more active, the ionosphere is thicker.

So things like flares and coronal mass ejections will make the ionosphere thicker!
