Hi,
I’m using S2 Level-1C and European Settlement Map products from 2015 together to train my classification model.
In this case, I’m trying to work on S2A_MSIL1C_20150823T083006_N0204_R021_T36SWH_20150823T083854.SAFE with MTD_MSIL1C.xml file shown below
For the preprocessing step, I tried to use Sen2Cor v2.11 and Sen2Cor v2.9 yet, I got this error message below for the both versions.
Is there any way for me to preprocess this tile or access the correct version of Sen2Cor, since I couldn’t find any other released version?
Dear @gokdumano,
Thank you for you message.
We were able to download the product you mentioned S2A_MSIL1C_20150823T083006_N0204_R021_T36SWH_20150823T083854.SAFE and run a Sen2Cor processing with Sen2Cor version 2.11.
The issue you are facing happens at the very beginning of the process and could be related to a problem of disk space or permission rights where the L2A product is generated.
The correct Sen2Cor log should look like this:
“Sen2Cor. Version: 02.11.00, created: 2022.10.20, supporting Level-1C product version 14.2 - 14.9 started …
Old product version 14.2 detected, - will be updated to 14.6
Processing baseline will also be updated

We hope you find these suggestions useful.

Same problem with me, I noticed that there is no QI_data folder for the 2017 image. While the others that have QI_data folder ran smoothly.
Dear Sen2Cor users,
There are known reasons that can bring to this error in the processing of a Copernicus Sentinel-2 L1C product:
- length of the path to the products (for Windows based Sen2Cor Installation) (See FAQ-6, Long string path in Windows)
- old products that are not compliant with recent Product Specification (See FAQ-14, When processing old S2 products, form 2015 to 2017)
(Sen2Cor Frequently Asked Questions)
However if necessary, feel free to open a new ticket specifying:
- Information on the version of Sen2Cor in use
- Information on the platform (linux, windows)
- Command lines used (e.g. options used, etc. etc.)
- Log that results from running the L1C product on your version of Sen2Cor
- L2A_GIPP.xml file
- L1C product full name (e.g. S2B_MSIL1C_20220304T071159_N0400_R020_T38LRH_20220713T214644.SAFE)
- Any information that may be useful
