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 %).
Product ID | Stream | Product | Version | Orbits | Bias | Dispersion | Special features |

L2_O3_TCL | OFFL/RPRO | CCD | 02.04.01 02.05.00 |
2867-current | +19 % +3.8 DU |
25 % 4.6 DU |

The graphs below display the latest estimates of TROPOMI tropospheric O3 column data quality 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.
