Cosmic ray-driven electron-induced reaction theory quantifies spatiotemporal variations in lower-stratospheric ozone and temperature.

ABSTRACT: Cosmic rays (CRs) play an important role in affecting planetary and interstellar climate and environment. Here, we apply the CR-driven electron-induced reaction (CRE) theory of ozone depletion to obtain a quantitative understanding of spatiotemporal variations in Earth's lower-stratospheric ozone (LSO) and temperature, which provide fingerprints for the mechanisms of ozone depletion and examine the impact of nonhalogen greenhouse gases on the ozone layer. We first show from observations that both LSO and temperature display pronounced 11-y cyclic variations over Antarctica and mid-latitudes, while weak (no apparent) cyclic variations over the tropics. These observations are consistent with the prediction by the CRE theory. Second, our no-parameter CRE theoretical calculations give the vert
