Sentinel-3 L1 OLCI
OLCI (Ocean and Land Colour Instrument) Level-1 products feature Top-Of-Atmosphere (TOA) radiometric measurements in 21 spectral bands (400–1020 nm), are radiometrically corrected, calibrated and spectrally characterised. They are ortho-geolocated (latitude and longitude coordinates, altitude) and annotated with satellite position and pointing, landmarks and preliminary pixel classification (e.g. land/water/cloud masks).
OLCI products are generated in two resolutions: FR (Full Resolution 300 m) and RR (Reduced Resolution 1.2 km).
The Level-1 product provides radiances for each pixel in the instrument grid, each view and each OLCI channel, plus annotation data associated with OLCI pixels. The Level-1B products in EO processing mode contain calibrated, ortho-geolocated and spatially re-sampled Top Of Atmosphere (TOA) radiances for the 21 OLCI spectral bands. The associated error estimates are also contained in the measurement data files.
In Full Resolution products (i.e. at native instrument spatial resolution), these parameters are provided for each re-gridded pixel on the product image and for each removed pixel. In Reduced Resolution products (i.e. at a resolution four times coarser), the parameters are only provided on the product grid.
In addition to measurement datasets, annotation datasets provide:
- timestamps for each line of the product grid
- geolocation information for each pixel
- quality flags, concerning surface or cloud identification, invalid or cosmetically filled pixels
- meteorological variables for each tie-point (defined on a specific grid: every 16 pixels for RR and every 64 pixels for FR products)
- geographical information and angles associated with each tie-point
- instrument features and settings needed in further processing such as detector index or OLCI channels, central wavelength and bandwidths.
On this platform the NRT (near real time), STC (short time critical) and NTC (non time critical) products are available.
