The small differences between MSI and OLI equivalent spectral bands need to be adjusted. The OLI spectral bandpasses are used as reference, to which the MSI spectral bands are adjusted. The bandpass adjustment is a linear fit between equivalent spectral bands. The slope and offset coefficients were computed based on 500 hyperspectral spectra selected on 160 globally distributed Hyperion scenes processed to surface reflectance and used to synthesis MSI and OLI bands. MSI’s RSRs correspond to the version v2.0. The spectral differences between MSI onboard Sentinel-2A (S2A) and Sentinel-2B (S2B) are accounted. Note that the S2A CA and Blue bands RSRs correspond to S2B RSRs.

The table below shows coefficients of linear regression used to adjust from Sentinel-2A,B/MSI to Landsat 8/OLI.
