Abstract : We present the results of unified geophysical validation of errors bars of individual Level 2 vertical ozone profiles, measured by limb and nadir sensors participating in the Ozone_cci Project: GOMOS,MIPAS, SCIAMACHY, ACE-FTS, OSIRIS, SMR and IASI. This work is a part of Comprehensive Error Characterization Report of Ozone_cci Project. The validation is performed by comparing the squared mean error estimate with variance of a sample derived from the dataset, in a region with low natural variability, for different separation distances. The approach allows simultaneous validation of random component of uncertainty estimates and experimental estimate of the structure functions of ozone variations. In our presentation, we discuss how realistic we find the ozone profile uncertainties for different instruments to be.
