Remote sensing reflectance reconstruction to obtain water optical properties from MERIS multispectral satellite images [PDF]

, 2010
We use a multiple regression analysis and a data bank of about 400 reflectance spectra to reconstruct hyperspectral reflectances between 400 and 900 nm with a 5 nm step using only the values known at the wavelengths of the MERIS sensor level 2 data.
