L3B generation error

Biophysical Indicators (L3A) processor
#1

Dear Sen4CAP,

I am trying to generate the L3B products however the system goes always in error and he exit code is 1 with the following message:

Unable to find an HDR or xml file in path /mnt/archive/dwn_def/s2/default/testnld/S2B_MSIL2A_20200810T103629_N0214_R008_T31UFT_20200810T130121.zip. Unable to determine the product metadata file.

I checked and the zip file exist in the location specified.

please note that the site and all the configuration parameters are the NLD sample site provided by the Sen4CAP consortium. the S2 L2A product is a Sen2cor ESA standard product. The same error is given for my site of interest, regardless of which product I use in input.

can you please suggest any resolution?

Thank you,
andrea

Dear Andrea,

If you intend to use the L2A products from SciHub directly you need to modify the file /usr/share/sen2agri/sen2agri-services/config/services.properties and set the following key to true:

SciHubDataSource.Sentinel2.auto.uncompress=true

Unfortunately, you will have to delete from your site the already downloaded products (from downloader_history and product table) and redownload them with this new option (you will have to restart the sen4cap-services after changing the key).
We will consider setting this key by default to true in the config file.

Please let me know if it works for you.

Best regards,
Cosmin

HI Cosmin,

Thank you for you answer.

However, the key you mentioned is not present at all in my services.properties file. There is the key for Sentinel 1 only (SciHubDataSource.Sentinel1.auto.uncompress, which is currently set to false)

Shall I add the key entry under the Sentinel 1 entry?

Thank you,
Andrea

Yes, indeed, you can add it right after the S1 key.
We will add it explicitly in the next version of the services in the services.properties file.
