[Windows] Correct Sen2Cor Version For L1C S2 Image From 2015


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

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
