Abstract

Discussed are the basic approaches reported in literature for atmospheric correction
of airborne/spaceborne multispectral (visible to near infrared) images of clear waters
pertaining to open ocean conditions, i.e. case I waters according to Morel 's classifi-
cation. The extent of applicability and inherent limitations of such approaches are
analyzed and the persisting problems identified.

We analyze atmospheric correction problems and procedures arising from specific
spectral properties of water-leaving radiance in the case of inland and coastal waters,
which generally qualm as turbid/ productive waters or case II waters according to the
Morel classification. First, approaches reported in literature for atmospheric correction
of airbag me/spaceborne multispectral images pertaining to such waters are discussed.
Secondly, issues of validity and limits of applicability of the suggested atmospheric
removal procedures are also addressed accounting for natural variability in
concentrations of all optically active components: phytoplankton, suspended minerals,
dissolved organics, etc. Finally, the persisting problems are identified and examined.
