Based on the combination of SLSTR and OLCI products, SYN is SYN is composed of mainly three Level-2 product types:

• Surface reflectances and aerosol parameters over land projected on OLCI 300 m grid for all SLSTR and OLCI channels (except SLSTR thermal bands; SLSTR 1374 nm band dedicated to Cloud detection and OLCI O2 and Water Vapour absorption bands)
• SPOT continuity products reproducing similar characteristics of the VEGETATION instrument observation. Ensuring the continuity of SPOT VEGETATION missions, its main aim is monitoring land use, its evolution and impact of weather and climate on agricultural activities. SYN is also an essential information source for worldwide food security. It would also be able to add to climate studies by supplying a continuous NDVI time series initiated by AVHRR and VEGETATION.
• Aerosol characteristics over land and sea projected on a 4.5 km resolution grid. The following sections outline SYN's applications. For further information about applications and services available, see:
