Hello @Rosellina
Maybe the differences here contribute?
http://step.esa.int/main/third-party-plugins-2/sen2cor/sen2cor_v2-8/
It is important to know, that the default configuration of the L2A algorithm provided with Sen2Cor version 2.8 is the same configuration as for the L2A “Core” Products processing in Sentinel-2 Ground Segment with L2A processing baseline 02.12. Therefore, no further tuning should be required on user side to get L2A Core Products. In order to generate products compatible with the L2A Core Products it is necessary to set the usage of a Digital Elevation Model to improve Scene Classification and have the activation of ESA-CCI data-package to be downloaded here and installed. The usage of ESA CCI data package for Sen2Cor v2.8 is detailed in the dedicated Software User Manual: S2-PDGS-MPC-L2A-SUM-V2.8.
The only differences between “L2A Toolbox” and L2A Core Products are reported in the following table:
| Category of Difference | Difference | L2A Toolbox | L2A Core Products |
|---|---|---|---|
| Product Format | HTML Folder | No | Yes |
| Manifest | Same Set of Items but arranged in different order | ||
| Product Quality Metadata | Copied from L1C | Generated by L2A On-line Quality Check (OLQC) | |
| Radiometry at Pixel Level | Digital Elevation Model | e.g. SRTM/DEM defined by the users | PlanetDEM |
| JPEG2000 encoding library | Kakadu | OpenJPEG |
