During the SORTIE field work in Hawaii and San Diego measurements of the upwelling spectral radiance distribution were made using the Nurads radiance distribution. In conjunction with these measurements the VSF was measured using the MASCOT sensor, along with other relevant inherent optical properties. The MASCOT sensor, as with all VSF scattering sensors, measures the volume scattering function for a small measurement volume whereas the VSF sampled by the radiance distribution is from an effectively much larger volume. Agreement between these two implies that there is no measurement scale problem. We will present the results of this comparison study.
