BackForward Variable: Ocean chlorophyll concentration

Definition
Full name Ocean chlorophyll concentration
Definition Indicator of living phytoplankton biomass, extracted from ocean colour observation. Uncertainty is expressed in mg/m3 for a given concentration of 1 mg/m3 .
Measuring Units mg/m3 Uncertainty Units mg/m3
Horizontal Res Units km Vertical Res Units
Stability Units mg/m3 (Stability /decade)

 

Comment: Requested in both open ocean and coastal zone.
