The TROPOMI Level 2 data products that are generated within the Copernicus ground system (or as otherwise noted) are listed in the table below. There are three different data streams: the near-real-time (NRTI) stream, the Offline stream (OFFL) and the Reprocessing (RPRO) stream. NRTI data are available within 3 hours after data acquisition and intended for users that need quick access to the data for operational applications. NRTI data may be incomplete and may not have the full data quality. Most data users should use the offline (OFFL) data, available within a few days after acquisition, or the latest version of reprocessed (RPRO) data. For long-term trend analysis data streams should not be mixed and the user is advised to use the latest version of reprocessed (RPRO) data to ensure uniformity of the data processing.
The data products contain information on the data quality for each TROPOMI ground pixel. It is essential that TROPOMI data users understand and apply the data quality indicators available in the data. Information about these quality fields in the "qa-value" is provided in both the Product Readme File (PRF) and the Product User Manual (PUM). Further information on the retrieval algorithms can be found in the Algorithm Theoretical Basis Document (ATBD). All ATBD, PUM, and Product Readme Files (PRF) are available in the documents section and a simple user guide is also provided. The TROPOMI team strongly encourages users to contact us with any questions on the data. User feedback helps improve the data quality. The latest data version information is provided per product page. Contact can be made via e-mail to EOSupport [at] Copernicus.esa.int.
