Product Global Ocean CDM (09/97-08/00)
Description The CDM data values represent the absorption coefficient due to detrital particulates and colored dissolved organic materials at 440 nm; and are reported in units of m-1. The contribution by the detrital particulates to the total CDM values is considered small.
These data are derived from a global analysis of SeaWiFS ocean color observations. Light absorption due to CDM is derived by decomposing SeaWiFS observations of water-leaving irradiance into the various components of light absorption and backscattering.
