Quality Control Activities
Sentinel-5P product quality issues are reported to users in the Product Readme Files (PRF), available in the Products and Algorithm. These files contain information on the overall data quality, changes between product revisions/collections and anomalies affecting the product quality. For Level 2 products, a high-level summary of validation results for every data product type (e.g. NO2, O3, SO2...) is also included.
The TROPOMI Portal for Instrument and Calibration is the system used for monitoring the instrument and its calibration. It provides a wide range of information including engineering and housekeeping data plots, instrument parameters monitoring and trends, life-limited items status, and weekly and monthly quality reports. This portal is primarily used by the Mission Performance Centre experts during their routine quality check activities.
The Level 2 web portal provides information on the TROPOMI Level 2 products quality based on daily statistics performed on different Level 2 parameters. This website is primarily used by the Mission Performance Centre experts during their routine quality check activities.
