The SENTINEL-3 SYN User Guide provides a high-level description of the SYN product which relies on the combination of the products of OLCI and SLSTR instruments. It also covers an introduction to relevant application areas, information on data distribution, product formatting and software tools available from ESA.

The categories are:

• Overview
  Gives a brief overview of the SYN heritage in the continuity of the SPOT VEGETATION mission.


• Applications
  Describes the support of the SENTINEL-3 SYN mission to land monitoring and security and climate change monitoring.


• Product Types
  Describes the granularity of SENTINEL-3 SYN products distributed to users: Level-2 SYN (surface reflectance and aerosol parameters over land), Level-2 VGP (TOA reflectances), Level-2 VG1 & V10 (VEGETATION-like products) and the global SYN AOD (Aerosol parameter over land and sea). The Level-1C product is not distributed to users.


• Processing Levels
  Illustrates the processing steps from Level-1 to Level-2, including the global SYN AOD module.
   
• Resolutions and Coverage
  Defines the spatial resolution, the radiometric resolutions and describes the coverage.

• Naming Conventions and Data Formats
  Describes the data naming conventions used and introduces the formatting used for SYN Level-2 products.


• Definitions
  Provides information on the units, notations and product grids used in the acquisition and processing of SYN products.

For an in-depth description of the mission's products and algorithms please refer to the Copernicus Sentinel-3 SYN Technical Guide. The detailed information available in the Technical Guide is intended for users such as academics and industrial software engineers who have previous experience of similar EO missions, and in-depth experience of data manipulation and management.
