Title: EMIS - MERIS Monthly mean sea surface diffuse attenuation coefficient at 490nm (4km) in m^-1
Point of contact:
Water Transparency (Diffuse attenuation coefficient at 490nm, Kd490 in m^-1 at 4km 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 indicator of water ...
emis.jrc.ec.europa.eu: The Environmental Marine Information System (EMIS) provides information on marine ecosystems and coastal state, using biological and physical variables generated by satellite remote sensing. EMIS allows visualisation and download of Remote Sensing Ocean color data and derived products hosted at the Institute for Environment and Sustainability (IES).
