VDAf Validation Server

The Sentinel-5p Mission Performance Centre provides an operational validation service relying on the VDAF Automated Validation Server (VDAF-AVS).  This fully automated data analysis system collects correlative measurements from quality-controlled monitoring networks and compares them to Sentinel-5p data using community endorsed protocols.  It outputs a suite of traceable quality indicators enabling users to judge the fitness-for-purpose of the Sentinel-5p data.

The figure below illustrates the automated comparison of Sentinel-5p tropospheric O3 column data (CCD) with respect to correlative measurements acquired by an ozonesonde of the SHADOZ Network. More tropospheric O3 validation results are available at http://mpc-vdaf-server.tropomi.eu/o3-tcl
