Hyperspectral Radiometer for Global & Diffuse Irradiance

Developer: Peak Design Ltd
Supporting materials
Video: So-Rad and HSP1 installation on MV Armorique
Training guide: HSP1 Quickstart guide

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.

Apply HSP1 data

  • Measurements can be used to improve satellite water quality products by removing or correcting for atmospheric effects, especially in coastal or inland waters.
  • Improving data products from other surface-based instruments (such as other MONOCLE instruments) where a reference is normally too expensive
  • In situations where existing equipment is difficult or impossible to use such as moving platforms, boats, buoys or aircraft.
