Deployment of spectroradiometer

Deployment of LICOR spectroradiometer allowing the measurement of spectral upwelling and down-welling irradiance. In addition this radiometer is coupled to a natural fluorescence sensor which measures upward radiance at 685 nanometres which is due to phytoplankton sun-induced fluorescence, and reflects in some way its photosynthetic activity. The deployment is performed in coincidence with a satellite overpass.
