The self-shading measurement error of the upwelling irradiance that is due to the presence of the instrument housing of an optical spectrometer with the irradiance meter located on a sidearm was calculated with a Monte Carlo code. The dependence of the effect on the instrument dimensions, the values of real optical parameters, sea-surface roughness, and Sun zenith angle were all studied to estimate maximum errors for two possible configurations of a proposed new marine spectrophotometer.
