Validation Summary
The Sentinel-5p TROPOMI L2_O3_TCL data (CCD) are in good overall agreement with correlative ground-based measurements (SHADOZ ozonesonde) and with EOS-Aura OMI and Metop-B GOME-2 satellite data. Bias and dispersion estimates meet mission requirements (<25%).

The graphs below display the up-to-date estimates of TROPOMI tropospheric O3 data quality (combining V01 and V02) obtained from comparisons to ozonesonde. Shown are the median value (left) and the dispersion (right, 68% interpercentile) of the absolute difference TROPOMI minus ozonesonde, at each SHADOZ site (marker) in the 20o S - 20o N tropical belt. The blue line and light blue shade indicate the mean value and the standard deviation of the sample of station estimates for the SHADOZ network.
