Since the pioneering paintings of Clarke et a1. (1970) it's been recognized that chlorophyll a (or. extra more often than not. pigments) contained in phytoplankton in near-surface waters produced systematic adaptations within the colour of the sea which can be saw from airplane. As a right away results of this paintings. NASA built the Coastal quarter colour Scanner (CZCS). which was once introduced on Nimbus-G (now Nimbus-7) in October 1978. (A brief description of the CZCS is supplied in Appendix I. ) almost immediately earlier than release. on the IUCRM Colloquium on Passive Radiometry of the sea (June 1978). a operating staff on water colour measurements was once shaped to evaluate water colour distant sensing at the moment. A document (Morel and Gordon. 1980) was once ready which summarized the cutting-edge of the algorithms for atmospheric correction. and phytoplankton pigment and seston retrieval. and which incorporated innovations in regards to the layout of subsequent new release sensors. The water colour consultation of the COSPAR/SCOR/IUCRM Symposium 'Oceanography from area' held in Venice (May 1980. i. e •• within the post-launch interval) supplied the chance for a reassessment of the cutting-edge after having won a few adventure within the research of the preliminary CZCS imagery. Such an review is the aim of this evaluate paper. with a view to start with an overview of the fundamental physics of water colour distant sensing and the basics of atmospheric corrections. the current country of the constituent retrieval and atmospheric correction algorithms will then be significantly assessed.

Austin and Petzold (1981) have developed an algorithm which relates the attenuation coefficients for upwelling radiance and/or irradiance to the ratio of upwelled radiances at two wavelengths.
The seston algorithms in Table 2 must fail. The spectral behavior of Lu(A). and hence radiance ratios. are less significant than the high reflectance which characterizes this kind of waters.
