Ocean and land colour imaging instrument flown on Sentinel-3.
The Ocean and Land Colour Instrument is a passive optical push-broom imaging radiometer carried by the Sentinel-3 series for ocean and land colour observation.[1][2] It measures 21 spectral bands at 300 m resolution across all surfaces, with a 1270 km swath for wide-area marine and terrestrial coverage.[1][3] The operational band set is specified across 400-1020 nm; a broader 400-1200 nm instrument coverage statement is also associated with OLCI, so buyers comparing archives should check the exact band table used by each product feed.[3][2] OLCI carries Envisat MERIS heritage and adds bands plus improved signal-to-noise and glint-handling characteristics for modern ocean-colour processing.[1][2] Its demonstrated use includes ocean-colour water-leaving radiance retrieval on Sentinel-3B, making it relevant to chlorophyll, coastal water-quality and cross-mission continuity workflows where moderate-resolution visible/NIR radiometry is the controlling requirement.[1]
