QA4EO Atmospheric Composition Uncertainty Field Studies

The main technical objective of QA4EO is the assessment of the uncertainties of the operational level 2 atmospheric composition products derived especially (but not exclusively) from the TROPOMI instrument on board of the Sentinel 5 Precursor (S5p) satellite.
This was achieved by performing collocated airborne and ground based measurements of the respective products during dedicated field studies.
The field studies proposed are:
• Airborne and ground-based campaign 1 and 2 in the German Ruhr area (1.4.1)
• Airborne and ground-based campaign in Romania (2.2)
• COCCON ground based FTIR deployments (2.3)
• Support to the MAGIC campaign
• Support for ACCLIP campaign (D5f-- a summary of the measurements performed during the campaign) 2.5
• Support for HYTES campaign (D5g) 2.6

The purpose of this Final Report is to provide a full description of the field studies and the results from the comparison with S5p data. This includes full documentation of the processing steps followed and results of the analysis The final report contains also a comprehensive introduction of the context, a description of the programme of work and report on the activities performed and the main results achieved.
