Chlorophyll retrieval from CZCS: influence of atmospheric aerosols

Accurate chlorophyll concentration retrieval from satellite data is hampered by the aerosol scattering effects of the intervening atmosphere. The authors present an algorithm which employs a multivariate-optimisation to correct for atmospheric scattering. The method returns a value for chlorophyll concentration as well as a first estimate for aerosol content at pixel resolution. The authors demonstrate the method using in situ data co-located with CZCS data. Results indicate the method yields chlorophyll amounts to within expected uncertainties
