Upcoming changes to Copernicus Sentinel-5P products

13 July 2020

An update of the Copernicus Sentinel-5 Precursor (S5P) operation system is planned in the next weeks, which will impact the following products:

  • L2__O3____
  • L2__O3_TCL
  • L2__CLOUD_
  • L2__HCHO__
  • L2__SO2___

Changes in the algorithms and product format will occur with an updated processor version to 2.1.3.

The main impact on the data products of the processor upgrade is:

  • Improved O3 (NRTI) retrieval at high latitudes
  • Corrected the problem of the sun glint impacting Background correction for HCHO
  • Improvement of reference spectrum selection in SO2 (selection of another zone in case the reference sector is contaminated by a volcanic eruption)
  • CLOUD product improvement: over snow/ice conditions, small cloud fractions, cloud edges
  • qa_value parameter is improved (more reliable) for all products

Documentation addressing the changes is available in the document library as well as sample products.

Detailed information will be provided within the Product Readme Files after the switch to the new operations.
