The OLCI instrument measures reflected solar radiation from the Earth's surface and clouds simultaneously in 21 spectral bands.
OLCI products are available at two spatial resolutions:
- Full Resolution (FR) at approximately 300 m
- Reduced Resolution (RR) at approximately 1.2 km.
OLCI data is acquired in Full Resolution over Land and Ocean, but Level 1b processing can generate products in FR or RR resolutions, or both. Level 2 processing ingest either FR or RR Level 1b products and generate Level 2 products at the same resolution.
