Sentinel-3 OLCI EFR: Ocean and Land Color Instrument Earth Observation Full Resolution (COPERNICUS/S3/OLCI)
The Ocean and Land Color Instrument (OLCI) Earth Observation
Full Resolution (EFR) dataset contains top of atmosphere radiances
at 21 spectral bands with center wavelengths ranging between
0.4μm and 1.02μm at spatial resolution of 300m with
worldwide coverage every ~2 days.
OLCI is one of the instruments
in the ESA/EUMETSAT Sentinel-3 mission for measuring sea-surface
topography, sea- and land-surface temperature, ocean color and
land color with high-end accuracy and reliability to support
ocean forecasting systems, as well as environmental and climate
monitoring.
The Sentinel-3 OLCI instrument is based on the
optomechanical and imaging design of ENVISAT’s MERIS. It is designed
to retrieve the spectral distribution of upwelling radiance just
above the sea surface (the water-leaving radiance).
OLCI observation is performed simultaneously in 21 spectral bands
ranging from the visible to the near-infrared (400 to 1029nm).
