Short summary
We present regional Bayesian composites of ground-based ozone partial column records. Defining coherent regions using a CAMS (Copernicus Atmosphere Monitoring Service) representativeness study, we merge five instrument types using the BASIC (Ball et al., 2017) algorithm, reducing trend uncertainties by 9.4 % compared to a weighted mean. Results confirm upper stratospheric recovery, predominantly negative middle stratospheric trends, while lower stratospheric trends remain mostly non-significant.
