Absorption Coefficient of Phytoplankton at 443nm (aph in m^-1 at 9km resolution): The absorption coefficient aph represents the fraction of incident light absorbed by phytoplankton organisms. It is an index of variability of the phytoplankton biomass in marine...

Water Transparency (Diffuse attenuation coefficient at 490nm, Kd490 in m^-1 at 9km resolution): The diffuse attenuation coefficient Kd490 measures the light penetration in the water column at the blue-green wavelengths (ca. 490 nm). It represents a good indica...

Monthly anomalies sea surface Chlorophyll-a concentration (in mg.m^-3 (log10) at 2km resolution) derived from the SeaWiFS sensor (Satellite remote sensing Ocean color data): Chlorophyll is a photosynthetic pigment commonly present in all phytoplankton spe...

Monthly climatology bottom layer temperature (degree-C) derived from the different GETM hydrodynamic model implementations for EU regional seas. The bottom layer is defined as the last vertical layer of GETM. It thickness varies with total water depth and with...

Photosynthetically Active Radiation (PAR in Einstein.m^-2.day^-1 at 4km resolution): PAR is defined as the quantum energy flux from the sun in the spectral range 400 to 700 nm, usable in the process of photosynthesis by phytoplankton, benthic algae and seagras...
