Short summary
Modelling the response of the atmosphere and its constituents to 11-year solar variations is subject to a certain uncertainty arising from the solar irradiance data set used in the chemistry–climate model (CCM) and the applied CCM itself. This study reveals significant influences from both sources on the variations in the solar response in the stratosphere and mesosphere. However, there are also regions where the random, unexplained part of the variations in the solar response is largest.
