Important Notice:
Following consolidated user feedback, and to streamline the delivery of Sentinel-5P data within the CDSE please be informed that the delivery package (.zip) for Sentinel-5p products downloaded via the CDSE will be changed starting from 5 November 2022. The *.cdl file that is currently within the Sentinel-5p download .zip products is planned to be permanently removed for all Sentinel-5p archive.
Importantly, once the change is implemented, the product download service will provide to users directly the S-5p products in the native format (*.nc) instead of the concatenated *.zip file as currently. This will start with the fresh products and will gradually apply to downloads for the entire S-5p repository as the *cdl is gradually removed.
Removing *.cdl will start on 5 November 2024 and will last several weeks. As a part of this activity all traces and checksums as published via the catalogue and in the traceability service will be recalculated.
The rationale for this change is that the *.cdl content is redundant to internal metadata of the NetCDF file and therefore unnecessary. If needed this file can be re-produced with the ncdump tool which is part of NetCDF package (https://www.unidata.ucar.edu/software/netcdf/). Command to extract NetCDF header into .cdl file:
ncdump –h filename.nc > filename.cdl
Providing direct access to the data through the http download will facilitate online processing e.g. via STAC interfaces.
A follow-up notification will be published once the removal of files is completed.
