Description

The evolution of changes in the zonal mean vertical distribution of ozone from the set of models participating in the CCMI-2022 project, using data from the REF-D1 and REF-D2 series of simulations is examined. This work presents the effects of natural variability forcings, focusing on solar cycle effects, as well as ENSO and volcanic eruptions on ozone and temperature profiles using the regression analysis and tools presented in the LOTUS SPARC Project.
Results are compared to satellite-derived for their common periods, as well as to CMIP5 and CMIP6 ESMs with resolved stratosphere and interactive chemistry. An initial comparison between linear and DLM results in the lower stratosphere is also shown.
