Global distribution of photosynthetically available radiation on the seafloor
International audience A 21 year (1998–2018) continuous monthly data set of the global distribution of light (photosyntheti-cally available radiation, PAR, or irradiance) reaching the seabed is presented. This product uses ocean color andbathymetric data to estimate benthic irradiance, offering crit...
