Mission Performance Centre

What is the S5P/TROPOMI Mission Performance Centre (MPC)? 

The Sentinel-5 Precursor (S5P) is a single-satellite atmospheric composition mission that is part of the EU Copernicus programme and is a cooperative undertaking between ESA and the Kingdom of the Netherlands. S5P is the platform for the Tropospheric Monitoring Instrument (TROPOMI) payload. The system will deliver a new generation of atmospheric composition data products designed to directly feed downstream services related to atmosphere and climate. The objective of the MPC is to provide an operational service-based solution for:

  • The routine quality control of the operational S5P Level 1 and Level 2 data products;
  • The long-term monitoring of the TROPOMI instrument sensor performance and ageing as well as the S5P operational products;
  • The in-flight calibration and characterisation of the TROPOMI instrument on-board Sentinel-5 Precursor;
  • The validation of the Level-2 data products using external and independent datasets;
  • The maintenance and evolution of the calibration, validation and processing algorithms.


These objectives are being achieved with a team of experts capable of developing, implementing, providing and adapting the service according to the S5P MPC requirements. The MPC is the element within the S5P Ground Segment in charge of covering the following functionalities:

  • Calibration (CAL) – the objective of which is to update on-board and on-ground configuration data in order to meet product quality requirements.
  • Geophysical Validation (VAL) – the objective of which is to assess, by independent means with respect to the methods and tools used for calibration and retrieval, the quality of the generated data products. Validation functions provide feedback to calibration and data processors corrective and perfective maintenance activities.
  • Quality Control (QC) – the objective of which is to routinely monitor the health of the instrument, the detection of instrument degradation and to check if the derived products meet the quality requirements along mission lifetime.
  • Data processors and tools corrective and perfective maintenance (PTM) – the objective of which is to manage the updates of the processors, quality control tools, calibration tools and all auxiliary files in order to meet the product data quality requirements.
  • Communication (COM) – the objective of which is to provide ESA and other stakeholders -including end users - with relevant information on the status, data usage and data quality of the Sentinel-5 Precursor mission.


The MPC, therefore fulfills S5P mission requirements for quality control, calibration, validation and end-to-end system performance monitoring.
