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 xCH4 column data with respect to correlative measurements aquired by an FTIR instrument of the NDACC network. More methane validation results are available at http://mpc-vdaf-server.tropomi.eu/ch4
