Trees!
Trees store lots of environmental and atmospheric data in their trunks. When they get fossilized a lot of that information remains intact.
Also, ice cores. Layers of ice protect previous layers of ice from further contamination, so are a pretty good snapshot of the environment/atmosphere at a given point in time.

Wiki has more detailed information on how Miyake Events are "stored" in trees and ice cores.
