Minimize Product Types Introduction

The SYN branch of SENTINEL-3 processing is a synergy of OLCI OL_1_EFR and SLSTR SL_1_RBT products.  

The SYN product types are divided into six main products:

Level 1

SY_2_SYN___

Surface Reflectance and Aerosol parameters over Land

Available

Level 2

SY_2_VGP___

1 km VEGETATION-Like product (~VGT-P) - TOA Reflectance

SY_2_VGK___

Surface reflectance over Land– used as input for VG-S product

SY_2_VG1___

1 km VEGETATION-Like product (~VGT-S1) 1 day synthesis surface reflectance and NDVI

SY_2_V10___

1 km VEGETATION-Like product (~VGT-S10) 10 day synthesis surface reflectance and NDVI

SY_2_AOD___

Global Aerosol parameter over land and sea on super pixel resolution (4.5 km x 4.5 km)

Level-1

NOTE: Level-1 product is not disseminated to Users.

SY_1_MISR is the output of the SYN Level-1 processing. The Level-1 product provides the correspondence grids between OLCI reference channel in the acquisition geometry and the others OLCI and SLSTR channels in their L1B image grids.

Level-2

  • SY_2_SYN : surface reflectances for all SYN channels and aerosol parameters over Land
  • SY_2_VGK : surface reflectance associated with VGT channels and NDVI over land

NOTE: The SY_2_VGK product is the input of the VGT-S software, and are NOT disseminated to Users

  • SY_2_VGP : SPOT continuity products providing TOA reflectances
  • SY_2_VG1 SPOT continuity products providing maximum NDVI value composite received during 1 day
  • SY_2_V10 SPOT continuity products providing maximum NDVI value composite received during 10 days
  • SY_2_AOD Global product over land and sea providing Aerosol optical thickness, surface reflectance and several aerosol characteristics on a wider resolution (4.5 km).

Products labelled as _BW are the Browse products. These products serve to support the Users decisions and analysis of quality and suitability of the User products.
