Specifications and Quality¶
The Sentinel-2 MSI user guide, user handbook, and technical guide provide overview of the products and algorithms within the platform.

Specific to the Level-2A processing, the Level-2 Algorithm Overview provides additional information about Scene Classification (SC) and Atmospheric Correction (S2A2).

The Sentinel-2 MSI data quality reports (DQRs) provide regular updates about the geometric and radiometric performance of the data products.
