Radiometric Resolution

Radiometric resolution is a measure of the ability of an imaging system to record different levels of brightness or tone. The radiometric resolution of SENTINEL-2 is 12-bit. This gives a potential range of brightness levels from 0 - 4 095.

Naming Convention

https://sentinel.esa.int/web/sentinel/user-guides/sentinel-2-msi/naming-convention

The Mission Identifier (MMM) denotes the satellite and will be either S2A for the SENTINEL-2A instrument or S2B for the SENTINEL-2B instrument.
The File Class (CCCC) may be set to "OPER" for all products generated during the Operations Phase. During Validation or internal testing, other values can be defined.
The File Type (TTTTTTTTTT) consist of the File Category and File Semantic
TTTTTTTTTT = FFFFDDDDDD where:

FFFF = File Category and DDDDDD = Semantic Descriptor.
The File Category comprises 3 characters and an ending underscore "_". This sub-field allows the definition of file groups characterised by related information / configuration information / generated data / usage of the data / etc. The Semantic Descriptor comprises 6 characters. The Semantic Descriptor can be composed of uppercase letters, digits or underscores. The File Type for a product may be "PRD_MSIL0P" for Level-0, "PRD_MSIL1A" for Level-1A, "PRD_MSIL1B" for Level-1B, "PRD_MSIL1C" for Level-1C, "PRD_MSITCI", or for Level-2A; "PRD_USER2A"
The Instance Identifier contains the Site Centre (ssss) and Creation Date in UTC time (yyyymmddThhmmss). The Site Centre denotes the file originator or processing facility. The Site Centre may be set to "MTI_" for Matera CGS, "SGS_" for Svalbard CGS, "MPS_" for Maspalomas CGS, "EPA_" for Madrid PAC, "MPC_" for the MPC/CC centre, "UPA_", for the UK PAC, "EDRS" for the EDRS Exploitation Segment, plus Local Ground Stations ending in "L", and "USER" for L2 products. A combination of additional fields may be included and are distinguished by the leading character:
The Relative Orbit Number (ROOO) where OOO represents the relative orbit number.
The Applicability Time Period: (VyyyymmddThhmmss_YYYYMMDDTHHMMSS) appends the Validity Period Time fields (Start and Stop).
The Product Format (SAFE) indicates that the product is in SENTINEL SAFE format
