The HSP1 measures the spectrum of downwelling solar radiation, and how this is partitioned between Direct, Diffuse and Global Irradiance. This sensor provides a reference for the colour or spectral distribution of sunlight near the water's surface.
HSP1 can be used to improve the accuracy of other sensors making direct measurements of the reflected light from the water body.
