The Sentinel‐3 Global Land and Ocean Mission is currently in development as part of the European Commission's Copernicus program. The Sentinel‐3 mission plans to launch four satellites each having a design lifetime of 7.5 years starting with Sentinel‐3A in 2015 and Sentinel‐3B satellite to be launched at least 18 months later. Two Sentinel‐3 C and D satellites are in preparation as replacement units for the A and B satellites that collectively provide a 20‐year period of continuous observations. One of the primary instruments carried by the Sentinel‐3 mission is the Ocean and Land Color Imager (OLCI), which is a high accuracy visible near‐infrared pushbroom imaging spectrometer designed to provide continuity of land and ocean colour data following ENVISAT‐ MERIS. Each OLCI instrument has an improved design with respect to the predecessor ENVISAT‐MERIS including a baseline spatial resolution of 300 m over all land and ocean, more spectral bands, a daily revisit time (using two satellites in constellation) and improved signal to noise ratio. The field‐of‐view of OLCI arranged is a way to minimize sun‐glint contamination of ocean scene yet to allow full overlap with the Sea and Land Surface Temperature Radiometer (SLSTR) also flown on‐board Sentinel‐3.

    This chapter commences with a brief summary of the Sentinel‐3 mission requirements, its operations concept and optical products (as such this chapter also serves as introductory for chapter 32 of the same book, where the second optical payload, SLSTR, on board Sentinel‐3 is described). Then the OLCI design and the instrument characteristics are described. Finally, the expected electro‐optical performance prediction and the OLCI calibration activities are summarized.
