Following the renewal of the ESA S3 Processing Services, the former Land Processing Centre codes "LN1", "LN2" and "LN3" will no longer be used. Instead two new Centre Codes "PS1" and "PS2" will be used to identify the new Processing Services. Nominally "PS1" corresponds to the service performing the systematic processing of "S3-A" data and "PS2" to the service performing the systematic processing of "S3-B" data.

For example:

  • S3A_SL_2_LST____20220323T235901_20220324T000201_20220324T004828_0179_083_216_0540_PS1_O_NR_004.SEN3.zip
  • S3B_OL_1_EFR____20220321T005607_20220321T005907_20220321T091528_0179_064_031_1620_PS2_O_NT_002.SEN3.zip
  • S3B_SR_1_SRA___20220321T001700_20220321T002700_20220321T013919_0599_064_030_____PS2_O_NR_004.SEN3.zip

instead of:

  • S3A_SL_2_LST____20220323T235901_20220324T000201_20220324T023054_0179_083_216_0540_LN2_O_NR_004.SEN3.zip
  • S3B_OL_1_EFR____20220321T005607_20220321T005907_20220322T045220_0179_064_031_1620_LN1_O_NT_002.SEN3.zip
  • S3B_SR_1_SRA___20220321T001700_20220321T002700_20220321T011723_0599_064_030_____LN3_O_NR_004.SEN3.zip

Furthermore, the following information will be updated accordingly:

  • processing centre information present in the product manifest

  • Sentinel-3 file naming convention as:


Product Generating Centre
Consists of 3 characters, either uppercase letters or digits
Generating Centres for the Instrument data products:

LN1 = Land OLCI Processing and Archiving Centre, closed in 2022
LN2 = Land SLSTR and SYN Processing and Archiving Centre, closed in 2022
LN3 = Land Surface Topography Mission Processing and Archiving Centre, closed in 2022
PS1 = Land Processing Service 1 (nominal service for S3A)
PS2 = Land Processing Service 2 (nominal service for S3B)
MAR = Marine Processing and Archiving Centre
