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 illustration given hereafter shows the automated comparison of Sentinel-5p tropospheric HCHO column data with respect to correlative measurements acquired by a MAX-DOAS UV/Visible spectrometer of the Network for the Detection of Atmospheric COmposition Change.  More HCHO validation results are available at
