Validation Contribution

Validation against SHADOZ ozonesonde data confirms that the TROPOMI/S5p OFFL tropospheric O3 (L2_O3_TCL) data product meets mission requirements.
This web article summarizes the results of the validation of the first year of S5P OFFL tropospheric ozone column data products (v01.01.05, v01.01.06 and v01.01.07) against co-located vertically integrated ozonesonde profile data collected by the SHADOZ network. All quality indicators remain within mission requirements during the period 30 April 2018 – 25 April 2019. When compared to the ground-based network, QA-screened S5P data have a positive median bias of 14% or 2.7 DU, and the spread in the intercomparisons is 23% or 4.2 DU. Two types of sampling-related bias patterns can be discerned.
