Radiometric measurement with Trios Ramses system. All Trios measurements averaged over reliable common times. The viewing zenith angle was approx. 45°. The surface reflectance factors rho are only given for 40 or 50°. If rho is to high, there is an overcorrection of Lw and Rrs. For this three methods for correction are applied: constant factor rho, Mobley 1999 and Mobley 2015 (Mobley 1999 related to 50°, Mobley 2015 related to 40°).
