| Abstract: | The successful launch of ENVISAT in March 2002 has
given a great opportunity to understand the changes of
water colour with high spatial resolution. In this study,
the potential of MERIS sensor to describe variations of
optically active substances of Alqueva artificial lake is
investigated. Regular in situ measurements, from May
2004 to July 2005, are used in combination with MERIS
acquisitions. The surface reflectance is derived from
Level 1b MERIS data, using radiative transfer
calculations to account for the atmospheric effects. The
parameterizations obtained are used to map the
concentrations of chlorophyll-a, cyanobacteria and
suspended sediments. The results obtained are |
