Level 2 Products

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 (NRT) stream, the Offline stream and the Reprocessing stream. NRT data are available within 3 hours after data acquisition and intended for users that need quick access to the data. NRT data may be incomplete and may not have the full data quality. Most data users should use the offline data, available within a few days after acquisition, or the latest version of reprocessed data.

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 is provided in 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. 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]
