Copernicus Sentinel-5 Precursor (S5p), optimisation in the processing of SO2 and HCHO products

16 February 2022

An update of the Copernicus Sentinel-5 Precursor (S5p) operational ground-processing system is planned during 9/03/2022. This includes an optimisation in the processing of Sulfur Dioxide (SO2) and Formaldehyde (HCHO) products, and an update/addition of related metadata:

  • The global attribute "Status_reference_spectrum" has been updated. Previous version could take values "solar" and "earth" while in the new one (version 2.3) it can take "solar" , "nominal_earth" and "fallback_earth"

  • The following additional metadata attributes are included in the background correction part of the products (/PRODUCT/SUPPORT_DATA/INPUT_DATA/BACKGROUND_CORRECTION/):

    • fallback_reference_date

    • fallback_reference_date_difference

    • fallback_aux_bg_source_filename

    • fallback_aux_bg_source_processingMode

    • fallback_l2_source_filename

    • fallback_l2_source_processingMode

    • fallback_l2_source_orbit

    • fallback_l2_source_sensing_time_start

    • fallback_l2_source_sensing_time_end

Sample data are available here.

Detailed information will be provided within the Product Readme File.

Please note that NRT products for data acquired during the downtime period will be not generated. After the successful deployment of the new system, version numbers of the first orbit generated with the new version of the S5P operational processors both, in NRT and OFFL, will be provided.
