An update of the Copernicus Sentinel-5 Precursor (S5p) operational ground-processing system is planned by mid-July 2022. This includes changes in the algorithms and product format for all products. The main impact on the data products of the processors upgrade is:
-
L1b Radiance degradation correction (the Irradiance degradation correction was already in place).
-
Usage of a Directional surface Lambertian Equivalent Reflectivity (DLER) database based on TROPOMI data, replacing OMI LER (for NO2 and O3 Profile) and GOME LER (for ALH).
-
CO product:
-
The unit of the column_averaging_kernel has changed from metres to unitless.
-
Inclusion of a priori profiles in the output product.
-
-
AAI product: a new wavelength pair using 335 and 367 nm to perform an aerosol index calculation has been added.
-
Updates of the correction factors to account for the radiance degradation correction of the updated L1b, mainly affecting CLOUD and Ozone Near Real Time (NRT).
-
Updated the CLOUD neural networks for clear-sky and cloudy
More details on the algorithm updates and format changes are available to the user community, together with sample data.
Full detailed information will be provided within the Product Readme Files after the operational switch.
Another news will be published when the precise date for the update is established. 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.
