Abstract: Photosynthetically available radiation (PAR) incident at the sea surface penetrates into the water column and drives oceanic primary production. Ecosystem models to estimate phytoplankton biomass and primary production require an estimate of sea surface PAR,… read more here.

Abstract: Instantaneous photosynthetically available radiation (IPAR) at the ocean surface and its vertical profile below the surface play a critical role in models to calculate net primary productivity of marine phytoplankton. In this work, we report… read more here.

Abstract: Biogeochemical (BGC) Argo floats currently measure downwelling planar irradiance (Ed) at three spectral wavelengths (380, 443, and 490 nm) and photosynthetically available radiation (PAR) in the 400-700 nm range. In next-generation floats, replacing the PAR… read more here.
