Data Format
Resolution
150 m (goal 100 m)
[Best Resolution: 150m]
Swath
~1400km (similar to OLCI)
[Max Swath: 1400 km]
Accuracy
The combined standard radiometric uncertainty (CRU) of the L1b TOA radiance for all bands shall be ≤ 2% (goal ≤ 1%.)
Max relative uncertainties for water reflectance over ocean: 350 to 400 nm: 0.0057 or 20%, 400 to 600 nm: 0.0020 or 5%, 600 to 710 nm: 0.0007 or 10%
Waveband
All OLCI bands, plus ~200 bands in 340-1020 nm with variable bandwidth (1.25 to 15 nm). Goal of full 340-1020 spectrum at 1.25-nm resolution.
