Product Types Introduction
The OLCI product types distributed to Users are divided into three main products.
The Level-1 product provides radiances for each pixel in the instrument grid, each view and each OLCI channel, plus annotation data associated to OLCI pixels.
In addition to the Level-1B OLCI product, the SENTINEL-3 SYN product is produced by combining products of OLCI and SLSTR instruments. More information on the SYN product can be found on the Sentinel-3 Synergy User Guide pages.
The level-2 land product provides land and atmospheric geophysical parameters computed for full and Reduced Resolution.
OLCI Level2 Products are:
The Level-2 water product provides water and atmospheric geophysical parameters computed for Full and Reduced Resolution.
Sentinel 3 OLCI products can be associated with different timeliness:
As consequences, OLCI L1/L2 scenes can be found twice, processed in NRT and NTC conditions and including the following suffix "NR" or "NT" in their filename.
The differences between NRT and NTC products are due to auxiliary data : consolidated Orbit files used in NTC processing; Forecast ECMWF Meteorological dataset used in NRT processing instead of analysis ECMWF data in NTC processing.
