Satellite-based estimates of downwelling solar radiation in the 400–700 nm range available for photosynthesis at the ocean surface. The data quantifies daily usable light energy in moles of photons per square meter (mol photons m⁻² d⁻¹). This Level-3 binned product is sourced from the OrbView-2 SeaWiFS mission and is used to estimate marine primary production and interpret phytoplankton dynamics.
Satellite-based estimates quantify the daily amount of solar radiation in the 400–700 nm range available for photosynthesis at the ocean surface. The data, expressed in moles of photons per square meter, are produced by OB_CLOUD and were last updated in December 2010. These estimates are used to interpret phytoplankton bloom dynamics and support marine ecosystem models.
