OLCI observes in 21 narrow spectral bands of the visible and near infrared spectrum at a resolution of 300m, with a swath width of 1270km and five tilted cameras, which are specially optimised to reduce sunglint, the ocean and land colour instrument.
It expands the medium resolution ocean colour measurements collected by Envisat’s MERIS instrument (2002–2012).
Main characteristics
- Swath width: 1270km.
- Push-broom imaging spectrometer with five cameras, mitigation of sunglint contamination by tilting cameras in westerly direction.
- Spatial sampling: 300m @ SSP.
- Spectrum: 21 bands [0.4–1.02]µm.
- Radiometric accuracy: 2% abs, 0.1% rel.
- Launch mass: 153kg.
- Size: 1.3m3.
- Design lifetime: 7.5 years.
