File Naming Convention:


  • MMM = the mission ID: S3A = SENTINEL-3A, S3B = SENTINEL-3B, S3_ = Both A and B
  • OL is the data source/consumer (OL = OLCI)
  • L = the processing level
  • TTTTTT = the data Type ID ("EFR___" = TOA radiances at full resolution)
  • yyyymmddThhmmss is the sensing start time
  • YYYYMMDDTHHMMSS is the sensing stop time
  • YYYYMMDDTHHMMSS is the product creation date
  • [instance ID] The field consists of 17 characters, either uppercase letters or digits or underscores "_".
  • GGG identifies the processing center that generated the file
  • [class ID] identifies the class ID for instrument data products with conventional sequence P_XX_NNN, where P is the platform, XX is the timeliness of the workflow, and NNN is the baseline collection
  • .SEN3 is the filename extension
